Adobe Commerce vs Mage-OS

Adobe Commerce is a paid edition with a commercial license, and its price depends on your ordering document with Adobe, so ask Adobe for your own figures. Mage-OS is free software under OSL-3.0, so it carries no license fee. The real comparison is the components around the software: hosting, extensions, developers, security monitoring and upgrades. With Adobe Commerce, the license and any cloud hosting are billed by Adobe. With Mage-OS, you pay the providers and people who run the store yourself, and those costs do not disappear just because the software is free.

The main one-time costs are the initial migration, store setup, theme and integration work, and testing of extensions on staging. These are typically project fees for an implementation partner or your own staff time. Recurring costs include servers or cloud infrastructure, managed database and search services, CDN and full-page caching, extension subscriptions, monitoring, backups and the people who apply patches and upgrades. Recurring costs usually outweigh the one-time migration over the life of the store, so model both over several years.

Several factors move the total:

• Catalog size, order volume and traffic peaks, which set the size of your hosting and search capacity.
• Number and type of extensions, since paid extensions carry their own license and renewal fees.
• Customizations and how many modules you maintain against each upstream release.
• Compliance scope, such as PCI DSS 4.0 work, which adds logging, testing and evidence collection.
• Your patch cadence, because security releases such as Mage-OS 3.5.0 and 3.6.0 need to be tested and deployed quickly.

Reducing custom code and choosing well-maintained extensions usually lowers the recurring figure most.

You do. Mage-OS publishes security releases that port Adobe's patches, but someone on your side or a contracted partner must watch for releases, test them against your extensions and theme, and deploy them to production. Budget for security monitoring, vulnerability scanning and on-call coverage for incidents. Ask any partner for the scope of patch windows, staging test coverage and emergency response, and whether that work is a retainer or billed per release. Mage-OS also recommends testing third-party extensions on staging first, which adds effort each cycle.

Adobe Commerce customers typically pay Adobe for support and cloud operations, and still need in-house or partner developers for customization. A self-hosted Mage-OS store moves more operational responsibility to you, including server administration, database tuning, search and cache configuration and upgrades. Whether you need a larger internal team depends on how much of that you already do. Ask for the number of roles, their skills and their share of time, and whether the engagement covers handover and documentation so your staff can take over later.

Ask for a written scope that lists each deliverable separately: environment setup, the migration script run on staging, extension compatibility testing, theme and integration work, data migration, performance testing, cutover and the documented rollback. Request assumptions about catalog size, extension count and custom modules, and ask what is excluded. Also ask for ongoing support terms, patch response, backup and restore testing, and how changes after go-live are priced. DeployOpen plans and implements these engagements under fixed-scope agreements, with ongoing support and testing available as retainers, and quotes follow from the written scope.

Your team can do it if it already has Magento or PHP operations experience, Composer skills and a tested deployment pipeline. Mage-OS publishes a migration guide that requires Composer 2.10.2 or newer and a Magento 2.4.8 or later starting point, and it documents a rollback to Magento Open Source. The risk lies in the tasks that are easy to underestimate: extension compatibility, security patch cycles, and performance under peak load. Assess those honestly against your staff's capacity before deciding, and consider a partner for the first migration with a plan to take over operations afterward.

Several items often go missing from early comparisons:

• Extension licenses and renewals, including modules that replace Adobe Commerce features such as B2B.
• Staging environments, which need hosting and maintenance of their own.
• Search, cache and queue services, such as OpenSearch, Redis or Valkey and RabbitMQ.
• Backup storage, disaster recovery testing and monitoring tools.
• Time spent by developers on upgrades between Mage-OS releases and Magento 2.4.x versions.

Add each to your model, and ask Adobe, your extension vendors and any partner to confirm current prices and terms in writing.

The effort depends mostly on how far the store has drifted from Magento Open Source. A move to Mage-OS starts with stepping down to Magento Open Source and removing Commerce-only modules, because the migration guide expects the store to be on Magento Open Source 2.4.8 or later with Composer 2.10.2 or newer. Effort rises with the number of custom modules, the number of third-party extensions that touch checkout, pricing or customer accounts, the amount of paid B2B functionality in use, and whether the store has its own Varnish or Fastly cache rules. Ask for a written inventory of Commerce-only features, extensions and customizations before accepting any estimate, because that inventory is what the rest of the effort is built on.

A team with experienced Magento developers can run the migration itself, because the Mage-OS migration guide is documented end to end and includes a rollback. The work that tends to need outside depth is the extension review, the removal of Commerce-only modules and the cache and search configuration on self-managed infrastructure. Be honest about your bench: check whether someone can own the Composer packages, the staging environment, the database restore plan and the post-cutover monitoring. If those roles are thin, a fixed-scope engagement with written deliverables can cover the gaps without handing over the store.

We do not publish a duration, and no timeline should be accepted until the scope is written. The timeline is set by the size of the inventory, the number of extensions that need replacing or retesting, the complexity of the B2B and pricing logic, the quality of the staging environment and how many release cycles the team needs to validate. Your own Adobe Commerce renewal or support dates also set a practical deadline, which the lifecycle policy and release schedule document, so confirm those dates with Adobe before planning. Ask any provider for a phased plan with milestones and acceptance criteria in writing.

Most of the delay in a store migration comes from client inputs, not from the platform. You need a staging environment that matches production closely enough to test checkout, tax, shipping and payment flows, plus a recent and sanitized copy of the data. You also need a named owner for each extension and customization who can confirm expected behavior, and someone who can approve test cases and sign off on each phase. Mage-OS advises testing third-party extensions on staging first, because its guide says compatibility should continue with little or no change but does not guarantee it. Ask your provider to list every input they need, with an owner and a due point, before work starts.

Mage-OS ports Adobe's security fixes rather than writing its own, so its patches follow Adobe's bulletins and are published after them. The Mage-OS release notes show this pattern: the 3.5.0 emergency release ported Adobe's hotfix for CVE-2026-75650, and 3.6.0 ported Adobe's October isolated patch APSB26-153. Mage-OS also lists faster security patch cycles among its additions over upstream, but you should measure that yourself by comparing the Mage-OS release date with the Adobe bulletin date for each advisory you care about. Adobe's own release schedule states that security patches ship at least annually for all supported lines, so your patch process should not assume a fixed interval.

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. Mage-OS lists PCI DSS 4.0 compliance work among its additions over upstream, but that does not make your store compliant, because compliance depends on your configuration, your payment flows and your assessor's findings. Ask your qualified assessor which evidence they expect, and we can help build the configuration, logging and change records that support that review.

DeployOpen plans, implements, customizes, integrates, hardens, backs up, upgrades, documents and supports self-hosted open-source platforms inside your own infrastructure, and most engagements are fixed-scope with scope, deliverables and timelines agreed in writing before work starts. Ongoing support, upgrades and continuous testing are available as retainers. We do not publish a price list, and a quote follows from the written scope. When you request one, ask for the components separately: discovery and inventory, migration build, extension work, testing, cutover, documentation and any retainer for patching and upgrades.
