Magento Open Source vs Adobe Commerce: what really differs

Sources: magento/magento2 on GitHub, B2B documentation, Google Tag Manager, 2.4.3 release notes, Upgrade Compatibility Tool, lifecycle policy and the October 2026 security bulletin. This is not Adobe’s full feature list. Check any feature you rely on against the current documents, because the boundary moves: the 2.4.9 notes say the clearCart GraphQL mutation, previously Commerce-only, is now in Open Source too.

• You sell to consumers, with no need for company accounts, negotiated quotes or shared catalogs.
• You have developers who can own the platform, including applying security patches by hand each month.
• Extensions cover your gaps at a total cost you have actually added up, including their upkeep.
• You are comfortable with no published Adobe support dates for your edition, and with community channels for help.

The saving is real, but the operating work moves to you. An unpatched store is a poor way to save a licence fee, so budget for someone to read each bulletin. If the shop is smaller and the budget is tight, it is also fair to ask whether Magento is the right platform at all. Our Bagisto vs Magento post looks at one option on Laravel.

• Native B2B matters: a company structure, approvals, quotes and buyer-specific catalogs.
• You want Adobe’s support, with the published dates and on-call support the lifecycle policy describes.
• You want Adobe to run the platform, on Commerce on Cloud or on the Cloud Service.
• You would otherwise pay for several extensions and their upgrades to get the same features.

Don’t decide on feature count alone. Name the three features your revenue depends on, and check how each is delivered in each product. Then price the licence with Adobe, and compare it against the build and upkeep of the alternative.

The technical foundations carry over: modules, plugins, observers and the service contract layer. A version decision is also similar, and the stack tables in our version and support matrix are a sensible starting point for planning either, with the caveat that Adobe’s lifecycle page doesn’t mention Open Source. For either product, a version move needs the same care, which is covered in what an upgrade involves.
