Google Workspace vs Nextcloud Hub: when each option fits
Google Workspace fits organizations that want a managed suite with little platform work, that accept Google's data regions for their residency rules, and that rely heavily on Gmail and Google Calendar. Nextcloud Hub fits organizations that need files, browser-based editing and collaboration on infrastructure they control, and that already have or will add a separate mail platform. Nextcloud Hub does not replace Gmail on its own, so a move away from Google usually means pairing it with a mail and calendar platform such as OX App Suite and confirming that design before you commit. The decision turns on four questions: where your data must physically reside, what your mail and calendar needs look like, whether your team is willing to run the platform, and how much real-time co-editing of Word, Excel and PowerPoint files matters day to day.
Start with data location. If a regulator or customer contract requires specific regions or on-premises control, check which Workspace edition and region options satisfy that requirement in writing, then compare them with a deployment in your own cloud account or data center. Next, map mail. Confirm which mailboxes, shared mailboxes, delegation rules and calendar sharing patterns you rely on, and whether your mail platform can carry them without losing history. Ask your mail vendor and your Nextcloud partner to show that design on a test tenant before any cutover.
Operating effort is the factor most often underestimated. A self-hosted Nextcloud instance needs regular upgrades, backups before each upgrade, and a plan for third-party apps, and Nextcloud requires that you move one major version at a time. Nextcloud GmbH's paid Standard, Premium and Ultimate subscriptions add support and maintenance terms, which you should weigh against in-house staffing. For editing, confirm how Collabora Online handles the Office formats and co-editing behavior your users depend on, and test it with real documents rather than assuming parity with Google Docs. If your team has little capacity to run servers, a managed or partner-run deployment may fit better than a purely internal one.
Which option fits which scenario
This table matches common buying situations to the platform that usually fits better, with the condition that makes each advantage matter. Read it against your own constraints, then confirm the open items for your environment before choosing. Most teams find that the deciding factors are operating capacity, data location and how much Gmail and Calendar depend on Google's service.
| Scenario | Better fit | Why |
|---|---|---|
| No appetite to run servers and no data residency rule | Google Workspace | Google operates the infrastructure, upgrades and backups. Self-hosting only pays off when someone on your team owns patching, backup testing and Nextcloud major upgrades. |
| Regulated buyer that must keep files in its own data center | Nextcloud Hub | Files and metadata stay in infrastructure you control. Confirm that your required controls and evidence can be produced from your own environment, and that your auditor accepts it. |
| Team leaving for license cost reasons | Depends on scale | Nextcloud Server is free to self-host, but Enterprise subscriptions, hosting and staff time recur. Compare total cost by component, and check whether your edition or data region requirements drive the Workspace price. |
| Company that relies on Gmail and Calendar for mail | Google Workspace | Nextcloud Hub does not replace Gmail on its own. Mail usually needs a separate groupware product such as OX App Suite, so plan a second system and a second migration before you move. |
| Team mostly editing Office files | Either, with Collabora Online | Collabora Online edits .docx, .xlsx and .pptx inside Nextcloud. Test co-editing and formatting fidelity with your own documents, since Google Docs native files need conversion. |
| Organization needing offline or air-gapped operation | Nextcloud Hub | Self-hosted Nextcloud runs without a public cloud dependency once installed. Confirm that every component you add, including the office editor, mail and updates, can also be delivered into the isolated network. |
How editing and mail needs change the choice
Google Docs, Sheets and Slides give knowledge workers browser co-editing with comments and suggestions in the same file, and most users never have to think about a server behind it. Nextcloud Hub handles file storage and sharing, and browser editing comes from Collabora Online, which integrates with Nextcloud. You run that office service yourself, so editing quality depends on your deployment and your support arrangements.
- Native in Google Workspace: browser co-editing, comments and suggestions with no separate editing server to operate.
- Nextcloud Hub with Collabora Online: co-editing of documents stored in Nextcloud, opened from the file browser.
- Edition choice: Collabora Online is licensed under the Mozilla Public License 2.0, and CODE is the free development edition. The enterprise edition adds support, SLAs and signed security updates, which is a recurring cost to weigh against your own operating capacity.
- Concurrent edit test: have several users edit the same document at once, then check cursors, comment threads and recovery after a dropped network connection.
- Daily feature test: confirm that the comment, suggestion and version features your teams use every day behave the same way under simultaneous edits.
Check whether these everyday editing workflows work for your heaviest users before you decide, because co-editing is the feature people will notice first after a move.
Mail-heavy teams depend on fast search across large mailboxes, delegated access, shared calendars and reliable mobile sync. Google Workspace delivers these inside one service. Nextcloud Hub covers file sharing, calendar and contacts, but a company domain's email and groupware usually needs a dedicated platform. OX App Suite from Open-Xchange provides email, calendar, documents, drive and tasks, and it can be deployed on premises. Dovecot is part of the Open-Xchange product line.
- Native in Google Workspace: Gmail search, shared calendars and mobile sync from one managed service.
- Nextcloud Hub: calendar and contacts alongside file sharing; confirm whether its mail client and calendar sharing meet your needs.
- Separate groupware platform: OX App Suite is the option to evaluate for email, calendar and tasks on your own servers.
- Export and import: the admin Data Export can write Gmail and Calendar data as zip files to Cloud Storage, and per-user Takeout is also available. Confirm which formats your target platform imports.
- Mail test: search large mailboxes, check delegated mailbox access, free and busy visibility for shared calendars, mobile sync, and spam filtering and deliverability.
Ask each team to list the mailbox and calendar behaviors it would miss most, then test those behaviors on the target platform before committing.
Teams that exchange .docx, .xlsx and .pptx files with customers, regulators or partners need the round trip to keep formatting, comments and tracked changes intact. Google Workspace converts Office files into its native formats on import and converts them again when files leave. Nextcloud Hub with Collabora Online edits Microsoft formats including .docx, .xlsx and .pptx in place, and ODF is its native format. The fidelity of each conversion is what you need to test, not the feature list.
- Native in Google Workspace: Office files open as Google formats, and exporting back to Office is a conversion step that should be sampled.
- Nextcloud Hub with Collabora Online: editing Office files where they are stored, without converting them first.
- Round trip test: use a set of your own files with tracked changes, comments, headers, footers, charts and embedded objects, then compare the output with the original.
- Macros and add-ins: list the VBA macros and add-ins your teams depend on and confirm whether the target editing environment runs them.
- Version history: confirm that Office files keep version history in Nextcloud and that co-editing works on the original Office files.
Select a sample from the most sensitive workflows, including files your auditors or customers review, and run each one through the full round trip before you decide.
How Google Workspace and Nextcloud Hub compare on capabilities
This table sets Google Workspace against Nextcloud Hub with open-source components across the capabilities that usually decide a move. Read each row as a question to confirm in your own environment, since editions, limits and add-ons change. The main takeaway is that Nextcloud covers files, browser editing and identity well, but mail and calendar need a separate platform.
| Capability | Google Workspace | Nextcloud Hub with open-source components |
|---|---|---|
| Real-time document editing | Native co-editing in Docs, Sheets and Slides with comments and version history in the browser | Collabora Online (MPL 2.0) edits .docx, .xlsx and .pptx inside Nextcloud. Confirm co-editing, comments and format fidelity with your own documents before committing |
| File storage and sync | Drive with shared drives and desktop sync client, managed centrally by administrators | Nextcloud Files with desktop and mobile clients on your own servers. Confirm sync behavior for large folders and shared-folder permissions in a pilot |
| Mail and calendar | Gmail and Google Calendar are part of the suite | Not included in Nextcloud Hub. Mail and calendar need a separate platform such as OX App Suite or grommunio. Confirm the mail platform, its migration path and deliverability plan separately |
| Sharing and permissions | Sharing controls set by administrators and users, with domain-level policies | Share links, user and group shares and folder permissions on the server. Confirm how external sharing and expiry policies map to your governance rules |
| Storage limits and quotas | Limits and pooled storage depend on the Workspace edition purchased | Limited by your own disks and object storage. Confirm per-user quotas, backup capacity and growth planning with your infrastructure team |
| Encryption options | Encryption at rest and in transit by default. Client-side encryption is tied to specific higher editions | Encryption in transit is set by your web server and TLS configuration. Server-side and end-to-end options vary by app, so confirm each feature against current documentation |
| Admin controls | Central console with audit logs, policy settings and data export tooling | Administrator settings, apps and user management in the server, with the Data Export and retention processes built by you. Confirm audit logging needs with your assessor |
| Identity integration via LDAP, OpenID Connect and SAML | Native Google sign-in, with SSO to external identity providers through supported connectors | LDAP and Active Directory users log in with directory credentials. OpenID Connect and SAML backends are documented. Confirm the chosen backend against your identity provider |
| Operating effort | Vendor runs the service, patches and backups. Your team manages users, policies and data | Your team or a partner runs upgrades, backups and monitoring. Major releases must be applied one at a time, and Nextcloud 35 is supported until September 2027 |
Where the data lives and who holds the keys
Google Workspace and Nextcloud Hub differ mainly in who operates the infrastructure, who can reach the encryption keys and who must produce evidence for an assessor. The cards below walk through those decisions in the order a review board usually raises them.
Data location and hosting model
Google Workspace stores data in Google-managed cloud infrastructure, and the regions available depend on your edition and contract. Nextcloud Hub can run in your own cloud account, your data center or an air-gapped network, or through Nextcloud One managed hosting, which Nextcloud sells to organizations under 100 users. A self-hosted deployment matters when a regulator or internal policy requires named locations, restricted administrator access or no external processor. Ask Google which regions and editions apply to your tenant, and confirm the hosting location of any Nextcloud managed plan in writing.
Encryption at rest and in transit
Both platforms encrypt data in transit with TLS and protect stored data, but the details differ. In a self-hosted Nextcloud deployment, you choose the disk, database and object storage encryption, and you decide where certificates are issued and stored. Check whether your Google edition includes the client-side encryption features you need, since these are edition-dependent. Document the encryption configuration for each data store, including backups, so the evidence matches the running system.
Who controls the encryption keys
The key question is whether your organization, or only the provider, can read stored content. With Google Workspace, key management follows the edition and features you buy, and the provider operates the underlying key infrastructure. With self-hosted Nextcloud, your team holds the server keys, database credentials and backup keys, and loses them only through its own process failures. Decide who may hold, rotate and recover each key, and write that process down before go-live. Confirm with Google exactly which keys are customer-managed for your edition.
Identity and directory integration
Most regulated buyers need one sign-in path for staff, with access removed when someone leaves. Google Workspace uses Google accounts as its identity source, with its own admin console and SSO options. Nextcloud can connect to LDAP and Active Directory so directory users appear in Nextcloud and sign in with their directory credentials, and it also documents OpenID Connect and SAML backends. Map your joiner, mover and leaver process to each option, and test deprovisioning, because a disabled directory account should lose access in Nextcloud too.
Compliance readiness and evidence
A self-hosted Nextcloud deployment moves control operation, logging and evidence collection to your team, which is where most audit questions land. DeployOpen plans, configures and documents controls and prepares the evidence an assessment will ask for. Independent auditors and certification bodies issue the reports and attestations, and DeployOpen does not. Before choosing a path, ask your assessor which frameworks and control evidence apply, and whether Google's existing assurance documentation already covers the scope you need.
Who runs the platform, day to day
Google operates the service, patches it and handles availability, so your team mainly administers accounts and sharing. With self-hosted Nextcloud, your team or a partner owns the server, database, updates, backups and monitoring. Nextcloud requires upgrades one major version at a time with a backup before each, so the operating model should name an owner for that cycle. Nextcloud GmbH's Standard, Premium and Ultimate subscriptions add vendor support and maintenance terms, and you should confirm which support levels your operations model requires.
What drives the cost of each side
On the Google Workspace side, the recurring cost is a per-user subscription, and the edition a buyer chooses sets which controls are available. Data regions and client-side encryption are not universal features; whether they are offered depends on the edition, so the first step is to confirm in writing which edition covers each control the organization needs and what the per-user price is for that edition in the buyer's own contract. Ask the reseller or Google account team to itemize seats, add-ons and any storage pooling, and to state whether a higher edition is required for data region selection or client-side encryption. Those requirements, not the base seat count, are usually what pushes the total up.
On the Nextcloud Hub side, the software itself is free to self-host under the AGPL, so the costs are infrastructure and people. Recurring items include compute and storage, database hosting (MariaDB, PostgreSQL or MySQL, as listed in the system requirements), PHP and web server operations, the Collabora Online server if browser editing is needed, the mail platform, backup storage and the staff or partner hours for patching and upgrades. Nextcloud must be upgraded one major version at a time, which makes upgrade hours a recurring line. An optional Nextcloud Enterprise subscription adds support and extra features. Its list prices on the pricing page start at 71.29 euros per user per year for Standard, 104.99 euros for Premium and 204.75 euros for Ultimate, for 100 or more users, with a 100-user minimum. Confirm with Nextcloud whether these figures still apply and what discounts or minimums apply to the organization.
One-time costs include the migration, design, integration with identity, the mail platform setup and testing, and the first hardening pass. Recurring costs include subscriptions, hosting, backup retention, monitoring, upgrades and support. When requesting a quote, ask for each item separately: the scope and deliverables in writing, who performs the Collabora, mail and storage work, the expected support tier and response times, the upgrade approach for each major release, who owns backup restore testing, and what happens to data exported from Google if the migration is paused. A quote that lumps infrastructure, licensing and labour together makes the comparison with the Google subscription impossible to check.
What leaving Google Workspace involves
The sequence turns a Google Workspace estate into a documented, tested Nextcloud Hub environment with mail and calendar moved, sharing rebuilt and users cut over with a known rollback path. Each step ends with a check the team can sign off.
Inventory data, sharing and integrations
The Google Workspace administrator and data owners list what the organization actually holds: Gmail and Calendar accounts, Drive folders and shared drives, native Docs, Sheets and Slides files, Chat spaces, and third-party apps connected through OAuth. They also record who shares what with whom, including external links and groups. The step is done when every data set has an owner, a size estimate taken from the admin console, and a decision to migrate, archive or delete it.
Plan the export window and retention
The team confirms with the Google Workspace admin that the account used for the Data Export meets the at-least-30-day age requirement, and reviews the edition and license terms that apply. Exports typically take about 72 hours and can take up to 14 days, and the default Cloud Storage bucket is deleted after 60 days, so the plan sets a copy-out date before that deletion. The output is a written schedule that names who downloads each archive and where it is stored.
Run the admin export or per-user Takeout
A super administrator runs the Data Export tool to write Gmail, Drive, Chat and Calendar data as zip files into a Cloud Storage bucket, and the team copies the archives to controlled storage before the bucket expires. Where administrators allow it, individual users can also run Google Takeout for their own data, which covers items such as personal Drive files and calendars. The step is complete when checksums or file counts match the inventory and every archive is stored in a location the organization controls.
Convert native Google files
Google Docs, Sheets and Slides are not stored as Office or OpenDocument files, so the team converts them to formats that Collabora Online can open and edit inside Nextcloud. The team samples documents with comments, tracked changes, complex tables and embedded charts to see what survives conversion and records the known gaps. The step is done when a reviewed sample of each file type opens correctly in the target editor and the owners have accepted the differences.
Import mail, calendars and contacts
Gmail content is moved into the chosen mail platform, such as OX App Suite, using the import method that platform supports, and calendars and contacts are converted to the formats it accepts. Mail routing, MX records, spam filtering and deliverability are reviewed before any production mailbox receives traffic. The step is finished when test mailboxes show complete folders, correct timestamps, working calendar invitations and passing message delivery checks.
Rebuild identity, groups and sharing
Users, groups and shared folder permissions are recreated in the new environment, normally by connecting Nextcloud to the organization's LDAP or Active Directory, or to an OpenID Connect or SAML provider, so that logins follow existing directory accounts. Shared drives and link-sharing rules are mapped to folders and permissions, and external shares are reviewed one by one. The output is a permission map signed off by data owners, with every access grant traceable to a group.
Pilot with a user group and set the operating plan
A small pilot group works in the new environment for a defined period, reporting conversion issues, sync problems and missing sharing. The operating plan is written at the same time: Nextcloud releases a new major version every four months and supports each for one year, and administrators must upgrade one major version at a time, back up before every upgrade and disable third-party apps until they are confirmed compatible. The step ends when the pilot defects are closed and the upgrade runbook has been tested on a copy.
Run cutover and decommission Google Workspace
The team moves all remaining users, switches DNS and mail routing, updates links in documentation and mobile devices, and freezes writes to Google Workspace for the final sync. After a hold period set by the organization, Google services are disabled, the exported archives are retained under the records policy, and the account is closed. Completion is shown by a cutover log, a clean post-cutover audit of mail flow and access, and a signed decommission record.
Questions buyers ask before moving off Google Workspace
How much effort does running Nextcloud Hub take, and what skills does the team need?
Running Nextcloud Hub is an ongoing operations job, not a one-time install. The effort depends on how many users you have, how many integrations and third-party apps you enable, and how strict your availability and backup targets are. Nextcloud itself is written mainly in PHP and JavaScript/TypeScript, so the team needs working knowledge of a Linux web stack, a supported database such as MariaDB or PostgreSQL, PHP-FPM with Apache or nginx, backups, certificates and directory integration. Nextcloud All-in-One is the official installation method and bundles caching, PostgreSQL, backups and antivirus, which lowers the setup burden. Confirm with your own platform team how they will own patching, monitoring and on-call before you commit to a design.
Can our team do the Google Workspace migration itself, or do we need outside help?
A team with Linux, database and identity skills can often do the platform build in-house, but the migration work is where outside help usually pays off. The work includes running the admin Data Export or per-user Takeout, converting native Docs, Sheets and Slides files, importing mail and calendars into a groupware system, mapping sharing links and permissions, and testing with pilot users. Google's Data Export requires a super administrator account at least 30 days old and delivers zip files into a Cloud Storage bucket, so someone must own that step and the download. DeployOpen plans, implements, integrates, hardens and documents self-hosted platforms in your own infrastructure, typically under a fixed scope agreed in writing. Ask for a written scope listing each data type, the cutover approach and the acceptance tests.
How long does a migration from Google Workspace take?
Duration depends mainly on data volume and on how long Google's export takes to run, plus the time your team needs for testing and cutover. Google states that Data Export exports typically take about 72 hours but can take up to 14 days, and that the default bucket is deleted after 60 days, so the download window is a planning constraint. Mail volume, the number of shared drives, the count of native Google files that need conversion, and how many users must be trained all extend the timeline. Treat any single number as a starting point and confirm the phases, dependencies and acceptance criteria in the written scope before you schedule a cutover date.
Does Nextcloud replace Gmail and Google Calendar on its own?
No. Nextcloud Hub covers files, sharing, Talk and document collaboration with Collabora Online, but it does not replace Gmail as a mail service. Most teams that move off Google pair Nextcloud with a groupware system such as OX App Suite for email, calendar, contacts and tasks, then connect both through single sign-on and a shared directory. Open-Xchange offers OX App Suite on premises, in a public cloud or as the managed OX Cloud service, and Dovecot is part of its product line. Mail deliverability, spam filtering, mobile sync and calendar sharing need their own design and testing, so plan them as a separate workstream with its own owner.
What does Nextcloud Enterprise add, and when does the subscription matter?
Nextcloud Hub is free to self-host under the AGPL, so the software itself carries no license fee. Nextcloud GmbH sells Standard, Premium and Ultimate subscriptions that add support, additional features and maintenance. According to Nextcloud's pricing page, Standard includes one year of maintenance, Premium adds a maintenance lifecycle of five or more years plus clustered instance support, and Ultimate adds support up to 24/7 with response times down to one hour. The enterprise tiers are sold with a 100-user minimum. The subscription matters most when you need contractual support, a longer maintenance window, or clustering. Ask Nextcloud for current quotes, since list prices can change.
How do Nextcloud upgrades work, and why can they not skip major versions?
Nextcloud publishes a new major version every four months and supports each for one year through monthly maintenance releases. Nextcloud does not allow skipping major releases during upgrades, so administrators must move one major version at a time. Each step requires a backup before the upgrade and disabling third-party apps until their compatibility is confirmed. The sequence matters because database migrations and app compatibility are tested per version. Plan a recurring upgrade window, maintain a staging instance, and check the release schedule so your current version stays inside its support period. Confirm the upgrade path and rollback approach in your scope.
Does DeployOpen issue compliance certificates for our Nextcloud deployment?
No. DeployOpen prepares systems, controls and evidence for compliance assessments, but it does not issue audit reports, attestations or certifications. Independent auditors and certification bodies perform those assessments. In practice, DeployOpen can help you document configuration, access controls, backup and logging evidence, and the hardening steps behind them, so your auditor has material to review. Ask the auditor which evidence they need before scoping the work, and confirm in writing which controls DeployOpen will prepare.
