Which open-source runbook automation tool fits your operations team?
An operations team shortlisting open-source runbook automation tools should start with the shape of its work, not a feature grid. Rundeck fits teams that want self-service jobs run across a defined set of nodes, with access control, scheduling and logging around each job. StackStorm fits teams that want the platform to act when something happens, such as a sensor watching an external system, a rule matching the event to an action and a remediation running with an audit trail. AWX fits teams that already standardized on Ansible playbooks and want a web UI, REST API and task engine to run them. The choice is about workflow shape and the effort to operate the tool, not a feature race, because all three can run automation but they expect different starting points.
Rundeck's advantage matters most when operators need to run approved jobs without shell access to every server. Its Open Source edition is Apache-2.0 licensed, and its system requirements list a Java 17 runtime and an external database such as PostgreSQL or MySQL. Confirm with your own team that the embedded H2 default is replaced before any production use, since the documentation does not consider it safe for production. StackStorm's advantage matters when remediation must start from an event. Its sensors, triggers, actions and rules are deployed as packs, and its services depend on MongoDB and RabbitMQ, so plan for that stack and for the Kubernetes beta blueprint if you need high availability.
AWX's advantage matters only if your playbooks already live in Ansible and your team is comfortable on Kubernetes through the AWX Operator, which the project recommends for installation. Before committing, read the ansible/awx README, which states that the last release was published on July 2, 2024 and that releases are paused during a large-scale refactoring. Ask the project for its current plans and check the AWX releases page yourself. Whichever tool you pick, price the operating work of maintaining the database, upgrades, access rules and job content in your own environment, because that effort, more than licensing, usually decides the outcome.
Which open-source runbook automation tool suits which scenario
This table maps common operations scenarios to Rundeck, StackStorm and Ansible AWX, with the supplied fact behind each recommendation. Read it to find the tool whose architecture matches your main workload, then check the notes on AWX maintenance before you commit.
| Scenario | Best fit | Why |
|---|---|---|
| Self-service jobs for on-call and support staff | Rundeck | Its web console, access control and scheduling let non-engineers run approved jobs against a defined set of nodes, and it reaches Linux and Unix nodes over SSH with public-key authentication. |
| Event-driven remediation from monitoring alerts | StackStorm | Sensors watch external systems and fire triggers, and rules map those triggers to actions or workflows, which is the model built for responding to events rather than waiting for a person to click run. |
| Existing Ansible playbook estate | Ansible AWX | AWX provides a web UI, REST API and task engine built on Ansible, so existing playbooks carry over. Confirm its maintenance status first, since its last release was July 2, 2024. |
| Kubernetes-first platform team | Ansible AWX or StackStorm (confirm) | AWX is installed through the Apache-2.0 AWX Operator, which suits a cluster-native workflow. StackStorm publishes a beta Helm chart for an HA cluster on Kubernetes, so validate both against your own platform standards. |
| Small number of scheduled jobs | Rundeck | Rundeck Open Source is free for teams writing and running jobs at small scale, but its embedded H2 default is not considered safe for production, so plan an external database such as PostgreSQL from day one. |
| Mixed estate with SSH nodes and third-party event sources | Rundeck or StackStorm | Rundeck covers node execution with a resource model, while StackStorm's packs of integrations cover event-triggered actions. Confirm the specific integrations you need in the pack catalog. |
How Rundeck, StackStorm and Ansible AWX each work and how they are licensed
All three tools are open source under permissive licenses, but they solve different problems: self-service jobs, event-driven remediation, or an Ansible control plane. The cards below set out the core model, latest supplied release and one caveat for each, so you can check fit before comparing operating effort.
Rundeck open source
Rundeck is a runbook automation service with a web console, command line tools and a web API for running jobs across a set of nodes. Its open source edition is licensed under the Apache Software License 2.0, and the documentation describes it as free for teams that write and run jobs at small scale. The caveat is the default install, which uses the embedded H2 database, not considered safe for production. Plan for an external database and confirm how node access over SSH with public-key authentication will be managed.
Rundeck commercial offering
Runbook Automation, formerly Rundeck Enterprise and Process Automation, is PagerDuty's commercial product built on open source Rundeck. It is offered as Runbook Automation Self-Hosted and as SaaS, and it is not open source. The open source edition and the commercial offering share a codebase lineage, but paid features and support are sold separately. Before you standardize, ask PagerDuty which capabilities are included in each option and what the support terms are for your environment.
StackStorm event-driven model
StackStorm is an integration and automation platform licensed under Apache-2.0 that focuses on actions taken in response to events. Sensors are Python plugins that watch external systems and fire triggers, actions carry out outbound work such as SSH, HTTP or Docker, and rules map triggers to actions or workflows. Content is deployed in packs and shared through the StackStorm Exchange, which the repository describes as about 160 integration packs. The caveat is that every pack is code you must review, test and maintain.
StackStorm platform dependencies
StackStorm is built from loosely coupled microservices that communicate over a message bus and expose a REST API, CLI and web UI. Its services use MongoDB for storage and RabbitMQ for messaging, so an installation carries two stateful dependencies alongside the platform itself. A Helm chart for a high availability cluster on Kubernetes is available as a beta blueprint. Confirm that your team can operate MongoDB and RabbitMQ and that a beta blueprint meets your availability requirements before choosing this path.
AWX on Ansible
AWX provides a web-based user interface, a REST API and a task engine built on top of Ansible. Its repository is licensed under Apache-2.0, and it is one of the upstream projects for Red Hat Ansible Automation Platform, which is a commercial product and not open source. The AWX README states that releases are paused during a large-scale refactoring, and the last release is dated July 2, 2024. Check the current state of the refactoring and the upstream roadmap before adopting AWX for new long-term work.
AWX installation path
Since version 18.0, the AWX Operator is the preferred way to install AWX, and it is an Apache-2.0 Kubernetes operator built with the Operator SDK and Ansible. The Docker-based install is recommended only for development and test and has no official published release. The operator's latest supplied release, 2.19.1, matches the pause in AWX releases. Your platform team needs Kubernetes skills and must decide how to patch and upgrade the operator and AWX together, since the project is not shipping regular releases.
How the capabilities of Rundeck, StackStorm and AWX differ
This table compares licensing, architecture, storage and messaging, databases, Kubernetes install paths, access control, audit trails and commercial editions for Rundeck, StackStorm and AWX. Read each row against your own operating model, because the three tools answer different needs: self-service jobs, event-driven remediation, or an Ansible control plane. Where the supplied facts stop, the cell tells you what to confirm with the vendor or in a test install.
| Capability | Rundeck | StackStorm | AWX |
|---|---|---|---|
| License | Apache-2.0 for Rundeck Open Source | Apache-2.0 | Apache-2.0 for the AWX repository |
| Latest supplied release | v6.2.1, published September 9, 2026, with 6.3.0 release candidates following | v3.9.0, published January 12, 2026 | AWX 24.6.1, published July 2, 2024; releases are paused during a large-scale refactoring |
| Architecture | Single web console and API service that runs automation across a set of nodes | Loosely coupled microservices that communicate over a message bus and scale horizontally | Web UI, REST API and task engine built on Ansible, with a refactoring toward a pluggable, service-oriented design under way |
| Metadata store and messaging | Relational database for job and project data; confirm the messaging model for your version | MongoDB for storage and RabbitMQ for messaging | Confirm the current database and messaging components in the release you deploy |
| Supported databases | MariaDB 10.11.6 or later, MySQL 8.0.35 or 8.4 or later, PostgreSQL 15.5 or later, SQL Server 2022, Oracle 19c or later | Not covered by the supplied facts; confirm with the StackStorm documentation for your version | Confirm with the AWX Operator and README for the release you deploy |
| Embedded default database | H2 is the default in a basic install, and the documentation says it is not considered safe for production | Not covered by the supplied facts; confirm before planning a production install | Not covered by the supplied facts; confirm with the install guide |
| Kubernetes install path | Confirm the supported container or Kubernetes packaging with PagerDuty for your target platform | A Helm chart for a StackStorm HA cluster on Kubernetes is available as a beta blueprint | AWX Operator is the preferred install since version 18.0; the Docker-based install is for development and test only |
| Authentication and RBAC | Access control is listed; integrations cover external sources for authentication, and SSH nodes use public-key authentication | RBAC is in open source since version 3.4, including role assignment from LDAP group membership | Confirm the authentication sources and role model in the AWX documentation for your release |
| Audit trail | Logging is listed in the documentation; confirm the audit detail and export options for your version | Records every manual or automated action execution and can ship it to LogStash, Splunk, statsd or syslog | Confirm the job event and audit export options for your release |
| Commercial edition | Runbook Automation, offered as self-hosted and SaaS, built on open source Rundeck | Not covered by the supplied facts; confirm any paid offering with the vendor | Upstream project for Red Hat Ansible Automation Platform; confirm the packaging and support terms with Red Hat |
What open source and commercial editions change for each runbook tool
The license decides more than the feature list for this group, so start there. Rundeck Open Source is licensed under the Apache Software License 2.0, and the Rundeck documentation describes it as free for teams that write and run Rundeck jobs at small scale. That phrase is the boundary to test. A team that runs a few dozen jobs for one operations group sits inside it, while a platform team serving many business units should ask PagerDuty in writing where its use falls and what the paid tier adds. Runbook Automation, formerly Rundeck Enterprise and Process Automation, is PagerDuty's commercial offering built on open source Rundeck, available as Runbook Automation Self-Hosted or as SaaS. Confirm which of these fits your data residency rules before you pilot, because the deployment choice changes who operates the database and the console.
StackStorm is Apache-2.0 licensed, and its role-based access control was once an enterprise feature. It was donated to the Linux Foundation and has been available in open source since version 3.4, including role assignment from LDAP group membership. For a security or operations lead, this means you can test approval boundaries and group-based permissions without a paid edition, but you should still verify that the RBAC model covers your separation of duties before relying on it. AWX is Apache-2.0 licensed and serves as one of the upstream projects for Red Hat Ansible Automation Platform. Its open-source releases are paused, with the README pointing to a refactoring effort, so the commercial platform is where subscribed support and ongoing releases are most likely to be found. Ask Red Hat which product versions it supports and how upgrades from upstream AWX map to the subscription.
When you talk to any vendor, ask specific questions about support, paid features and renewal terms before signing. Ask which features are in the community code and which are gated, including audit export, SSO, approval workflows and high availability. Ask what the support window is for each version line, how security patches reach you, and whether renewals change price or scope mid-term. Ask for the exit path too: whether job definitions, credentials and audit history can be exported in open formats if you change tools. Get every answer in writing as part of the quote, since DeployOpen does not publish prices and each engagement follows from its agreed scope.
What running each runbook tool takes day to day
Rundeck runs as a single Java application backed by a relational database, so day-to-day work centers on the database and the server that hosts the console. The default install uses the embedded H2 database, which the Rundeck documentation says is not considered safe for production because it is not resilient if Rundeck is not shut down gracefully. Moving to an external database is therefore an early decision, not a later one.
- Database choice: The supported options listed in the system requirements are MariaDB 10.11.6 or later, MySQL 8.0.35 or 8.4 or later, PostgreSQL 15.5 or later, SQL Server 2022 and Oracle 19c or later. Your team will own backups, patching and failover for whichever one you pick.
- Java runtime: Plan for a Java 17 runtime and keep it current with your security baseline.
- Node access: Linux and Unix nodes are reached over SSH with public-key authentication, so key rotation and node inventory are recurring tasks.
- Job and project upkeep: Job definitions, schedules and option lists change as runbooks change, and someone must review them.
- Upgrade cadence: Rundeck v6.2.1 was published on September 9, 2026, with 6.3.0 release candidates following, so budget time for regular minor upgrades.
Before you commit, ask your Rundeck partner or PagerDuty to confirm the database sizing, backup approach and upgrade path for your node count and job volume.
StackStorm is a set of loosely coupled services that communicate over a message bus, so operating it means running and monitoring several components, not one application. The documentation for its high availability setup names MongoDB for storage and RabbitMQ for messaging, and a Helm chart for a StackStorm HA cluster on Kubernetes is available as a beta blueprint. Expect the platform team to own the data stores and the message bus alongside StackStorm itself.
- Service set: The API, auth, sensor, rules engine, workflow engine and action runner services each need monitoring, scaling and log collection.
- MongoDB and RabbitMQ: Both are stateful dependencies with their own backup, upgrade and failover procedures.
- Sensors: Each sensor is a Python plugin that watches an external system, so the number of sensors drives both load and the code you maintain.
- Pack and rule maintenance: Integrations, rules and workflows ship as packs stored as code. Pack versions, rule changes and Exchange content need review like any other code change.
- Audit shipping: Execution audit trails can go to LogStash, Splunk, statsd or syslog, so the log pipeline becomes part of the operating model.
Role-based access control is available in open source since version 3.4, including role assignment from LDAP group membership. Ask your StackStorm partner to confirm how your directory groups map to roles before rollout.
AWX is a Kubernetes-oriented control plane for Ansible, and its operating model depends on the AWX Operator. Since version 18.0 the AWX Operator is the preferred install method, and the Docker-based install is recommended only for development and test and has no official published release. Day-to-day work therefore centers on a Kubernetes cluster, the operator and the database behind AWX.
- Operator upkeep: The AWX Operator is an Apache-2.0 Kubernetes operator built with the Operator SDK and Ansible. Track its releases and upgrade the operator and AWX together.
- Paused release line: The AWX README states that the last release was published on July 2, 2024, and that releases are paused during a large-scale refactoring. AWX 24.6.1 is the latest release on the GitHub releases page, and AWX Operator 2.19.1 was published on the same date.
- Installation changes: The README links community posts on a pluggable, service-oriented architecture and on upcoming changes to Operator installation methods, so plan for change in how AWX is deployed.
- Playbook volume: Playbook count, inventory size and job frequency drive load on the control plane and the execution environments.
- Kubernetes familiarity: Your team needs cluster administration skills for upgrades, storage and networking.
Confirm with the Ansible project or your Red Hat contact what support path exists for AWX itself, since the public release line is paused.
How to choose and pilot an open-source runbook automation tool
This sequence turns a shortlist of Rundeck, StackStorm and Ansible AWX into a documented choice, backed by a pilot that tests the database, access control and audit trail you would run in production.
Inventory your highest-value runbooks by trigger type
The operations lead and two or three on-call engineers list the runbooks that consume the most time or carry the most risk, then tag each one as manual, scheduled or event-driven. A runbook that a monitoring alert should start points toward StackStorm's sensor and rule model, while a runbook an operator starts from a console or on a timetable points toward Rundeck's job model. Done means a ranked list with one trigger type per runbook and the target nodes each one touches.
Map each runbook to the three candidate tools
The platform team takes the ranked list and records, for each runbook, whether Rundeck, StackStorm or AWX covers it natively, through a plugin or integration, or needs custom code. Ansible playbooks already in use map directly to AWX, which is built on Ansible. Done means a grid where every runbook has a fit rating for each tool and a short note on the gap, so the team can see where one tool covers most of the work and where two tools would be needed.
Confirm license and maintenance status for each tool
The procurement lead and the security architect check each candidate's license and current release activity against the supplied release records: Rundeck Open Source under Apache-2.0 with a 6.x line, StackStorm under Apache-2.0 with a 3.x release, and AWX under Apache-2.0 with its releases paused since July 2, 2024. They also confirm which features sit in the commercial edition, such as Runbook Automation, and which are in the open-source build. Done means a written note per tool covering license, last release, paused or active status and any feature that depends on a paid edition.
Pilot on non-production nodes with the production database
The platform engineer deploys each shortlisted tool in a non-production environment and runs a representative set of jobs against a small, non-production node set reached over the same protocols production uses, such as SSH with public-key authentication. The pilot uses the same database engine you plan to run in production, because Rundeck's embedded H2 default is not considered safe for production. Done means a log of successful and failed job runs, recorded database settings, and a note on any node that could not be reached.
Test authentication and RBAC against your directory
The identity engineer connects each pilot to the directory your staff use, then tests that group membership maps to the right roles. For StackStorm, this includes confirming role assignment from LDAP group membership on the open-source build, and for Rundeck and AWX, that job and project permissions hold for users in each group. Test a user who should be denied, not only users who should succeed. Done means a signed-off access matrix that lists each group, the role it receives and the test result.
Review audit output and upgrade path with security
The security team reviews the audit trail each tool produces for a sample of manual and automated runs, checks that it can be shipped to your log platform, and confirms who can change jobs or rules. The platform lead then records the upgrade path, including the supported database versions and how minor and major releases are applied. Done means a sign-off that the audit records meet your retention needs, plus a written quote request. Ask the vendor or partner for the written scope, the supported database versions, the upgrade process, the support window for each release line and the deliverables for installation, hardening and documentation.
What do teams ask before running or hiring help for runbook automation?
How much effort does it take to run Rundeck, StackStorm or AWX yourself?
Running any of the three is an ongoing operations job, and the effort differs by platform. Rundeck needs a Java 17 runtime and an external database for production, since the embedded H2 database is not considered safe for production, so a team must maintain the server, the database and upgrades. StackStorm is built from several microservices that depend on MongoDB and RabbitMQ, which adds components to patch and monitor. AWX is installed through the AWX Operator on Kubernetes, so the team needs cluster skills. Confirm your team's Kubernetes, database and messaging experience before choosing.
Can an operations team self-host one of these tools without outside help?
Yes, if the team already runs the supporting stack and can own it after go-live. Rundeck is the lightest of the three to start with, because its open source edition runs with a web console, CLI and API and you can begin with a small set of jobs. StackStorm and AWX need more platform skills, and their open source paths carry extra design decisions around packs, message buses, clusters and access control. Plan for an internal owner for upgrades, backups and credentials even if outside help handles the build.
What drives the cost of implementing runbook automation?
The main cost drivers are the number of integrations, the number of nodes the jobs reach, the access model and the audit requirements. Each integration or external system needs a job or action written, tested and reviewed. Node count affects how much inventory and SSH key management you must design. Role-based access control, approval steps, database choice and audit log shipping add design and testing work. Software licensing for the open source tools is free under Apache-2.0, so most cost is labor, infrastructure and any paid edition or support you add. Ask any provider for a quote that lists each integration, node group, access role and log destination separately.
How long does a runbook automation pilot take?
A pilot usually covers a small set of runbooks against a limited group of nodes, and its length depends on how many runbooks, integrations and approval paths it includes. No researched duration is available for these tools, so the timeline should come from a written scope agreed before work starts. A useful pilot tests one or two high-frequency runbooks end to end, including credentials, logging and rollback. Ask for the pilot's exit criteria, such as which jobs must run successfully and which audit records must be produced, before agreeing on a schedule.
What must our team supply before a runbook automation project starts?
The team must supply the runbook inventory, a credentials policy and the approval rules, because automation cannot be designed without them. Inventory means the list of manual procedures, their owners, frequency, target nodes and risk. The credentials policy defines how SSH keys, API tokens and vault secrets are issued and rotated. Approvals define which actions need a second person and which can run unattended. Also provide a test environment, identity provider details for group-based roles, and the logging system that will receive audit records.
What should we do about AWX's paused releases?
Treat AWX as a platform with an uncertain release path and confirm its status before committing. The AWX README states that the last release was published on July 2, 2024 and that releases are paused during a large-scale refactoring, and the AWX Operator's latest release matches that date. The Docker-based install is recommended only for development and test, so production teams should plan around the AWX Operator. Ask whether you need an Ansible control plane specifically, and if so, review Red Hat Ansible Automation Platform, which the README names as a downstream product built on AWX. Keep your playbooks portable so a move stays low-cost.
When is a paid edition or outside support worth reviewing?
Review a paid edition or support when you need features that the open source path does not provide, or when the operations team cannot carry the upkeep alone. For Rundeck, PagerDuty's Runbook Automation offering is built on the open source Rundeck and is offered self-hosted or as SaaS, so compare its terms against your access and support needs. For StackStorm, role-based access control is available in open source since version 3.4, so check whether your requirements go beyond it. Outside support fits well when you need an implementation, hardening, backups, upgrades or documented runbook controls on a fixed scope. DeployOpen plans, implements, hardens, backs up, upgrades and documents self-hosted platforms in your infrastructure, and most engagements are fixed-scope with written deliverables.
What is the cost of switching runbook tools later?
Switching cost depends mostly on how your jobs, rules and playbooks are stored and how many access and audit integrations depend on them. Rundeck jobs, StackStorm packs and AWX playbooks each use their own structures, so migrated content will need rewriting or adapting. Keep the runbook logic in version-controlled files, document credentials and approvals outside the tool, and record the audit trail in a central system. Ask any vendor or partner to estimate migration effort against your actual job count before deciding.
How DeployOpen scopes and delivers runbook automation work
DeployOpen plans, implements, integrates, hardens, documents and supports self-hosted open-source platforms inside your own infrastructure, so the runbook platform you choose runs in your cloud accounts, data centers or air-gapped network. Engagements start with a written scope that fixes deliverables and timelines before any work begins.
How we scope
- Agree which runbooks, target node groups and operator roles the written scope covers before work starts.
- Confirm the authentication source, such as directory groups, and how access control maps to each role.
- Record the database, network path to nodes and SSH key handling that the chosen platform will need.
How we build
- Install the selected platform in your environment, with a production database rather than the embedded default.
- Build job definitions, option passing, scheduling and error handling against the runbooks in scope.
- Test remediation actions and audit logging against your change and incident procedures before go-live.
How we hand over
- Deliver configuration, job inventory, access model and runbook documentation as part of the agreed deliverables.
- Walk your operations and security staff through backup, upgrade and rollback steps for the platform.
- Provide evidence of configuration and access controls that your compliance team can use in assessments.
How we support
- Offer ongoing support, upgrades and continuous testing as a retainer, priced separately from the initial scope.
- Plan platform upgrades against the vendor release activity you confirm for your chosen edition.
- Ask for a written quote that lists scope, deliverables, timelines and any retainer terms before you commit.
