Is Magento Open Source Still Actively Developed and Supported?

Yes, Magento Open Source is still being developed and patched. It runs on the same core codebase as Adobe Commerce, so when Adobe ships a new 2.4.x release, both editions get it at the same time. The difference is how long that support lasts and who can still get patches once a version ages out.

How Magento Open Source support actually works

Adobe treats Open Source and Commerce as two editions of one product. New features, security fixes, and version releases land in both at the same time. Adobe 2.4.9 released in May 2026 as the current long-term supported line, and 2.4.8 remains the more common upgrade target for stores still on older 2.4.x versions.

The catch is duration. Adobe’s standard policy gives each 2.4.x release three years of full support from its general availability date. After that, Adobe Commerce customers can still get patches for a period beyond that window. Open Source merchants cannot. A store still running Magento Open Source 2.4.5, for example, has been without official security patches since that version’s support window closed, while Adobe Commerce customers on the same version continued receiving them.

That gap is the main practical difference between the two editions when it comes to “supported.” Feature-wise they are the same product. Patch-wise, staying current on Open Source matters more, since there is no paid fallback once a version ages out.

Mage-OS: a support path independent of Adobe

Mage-OS is a separate, community-governed fork of Magento Open Source. It exists specifically to give the open-source side of the platform a future that doesn’t depend on Adobe’s commercial roadmap. Mage-OS tracks compatibility with the Magento ecosystem and ships its own releases, including PHP 8.5 support in its 2.3.0 release from May 2026. For merchants who want to stay on an actively maintained open-source Magento codebase without an Adobe contract, Mage-OS is a credible option, not just a fallback.

What this means for your store

If your store is on a currently supported 2.4.x version, Magento Open Source is being actively developed and patched right along with Adobe Commerce. The risk shows up when a store is left on an old version past its three-year window. At that point it stops getting official patches, regardless of edition, and PCI DSS compliance becomes the immediate concern for anyone processing card payments. Keeping track of where your specific version sits in Adobe’s support timeline is worth doing on a regular basis, not just when something breaks. Our Magento development team handles version audits and upgrades for stores in exactly this position.

The short version: Magento Open Source is not abandoned or frozen. It is actively maintained, shares Adobe’s release cycle, and now has Mage-OS as an independent alternative. The thing to actually watch is your specific version’s support end date, not the edition itself.
