OpenMage in 2026: The Honest State of Magento 1's Community Fork

What OpenMage actually is

OpenMage LTS is a fork of Magento CE 1.9 that the community picked up when Adobe walked away. The supported 20.0.x line is based on Magento 1.9.4.5 and saw its initial release on June 28, 2020, two days before official EOL. There is also a 19.4.x line dating to December 9, 2019, though the project strongly encourages everyone to follow the latest release. The code lives at github.com/OpenMage/magento-lts and the project site is openmage.org.

The important part for store owners: this is not a rewrite. OpenMage uses the same database schema, the same theme system, the same extension format, and the same admin panel as Magento 1. If your team knows Magento 1, they know OpenMage. If you bought extensions for Magento 1, most of them install on OpenMage the same way they always did. The fork's job is to keep that familiar platform patched, compatible with modern PHP, and free of the security holes that make abandoned software dangerous.

I was skeptical in 2020. Community forks of dead commercial software usually fizzle within two years. This one did not: commit activity runs right through July 2026, and the release history backs that up.

Release velocity: what shipped in the last nine months

Talk is cheap with volunteer projects, so look at the actual releases. Three landed in the last nine months, and none of them are token version bumps.

v20.16.0 (November 1, 2025)

Brought a custom admin URL security feature (a big deal for a platform that bots probe at /admin all day), a TinyMCE upgrade, and PHP 8.4+ compatibility fixes. Getting a 2008-era codebase to behave on PHP 8.4 is unglamorous work, and exactly the work that keeps stores off unsupported PHP.

v20.17.0 (April 18, 2026)

Five security fixes in one release, in the deserialization, file upload, and path traversal areas. Those three categories are precisely where Magento 1 sites get owned in the wild, so this is the fork earning its keep. The release also continued the migration off the abandoned Zend libraries onto modern alternatives (Monolog for logging, Symfony Validator for validation) and added .env file support, which makes multi-environment deployments far less painful.

v20.18.0 (May 4, 2026)

The current release as I write this. Three more security fixes: a reflected XSS in Data Flow profiles, an open redirect via the unvalidated uenc parameter, and a weak API session ID. On the feature side: native AVIF image support via GD on PHP 8.1+, the FedEx shipping backend rewritten from the end-of-life SOAP API to REST, a PSR logger, Zend_Captcha replaced with laminas/captcha, and a slow-query optimization in SalesRule's getActiveAttributes. Plus the usual bug fixes.

The modernization arc: this is not life support

There is a difference between a project that keeps a corpse warm and a project that modernizes. Reading the last few releases together, OpenMage is clearly in the second category, and the pattern is consistent.

PHP. Stock Magento 1 tops out around PHP 7.2, a version that has been dead for years. OpenMage moved its minimum to PHP 8.1 during the v20.14/20.15 era in 2024 and is actively fixing PHP 8.4+ compatibility. That single fact changes the hosting conversation completely: you can run OpenMage on a current, supported PHP with current performance characteristics, instead of pinning an EOL PHP build and hoping your host keeps offering it.

Libraries. Magento 1 was built on Zend Framework 1, which is long dead upstream. OpenMage has been systematically swapping those pieces out: Monolog and a PSR logger for logging, Symfony Validator for validation, laminas/captcha replacing Zend_Captcha. This is the boring structural work that determines whether the platform is still viable in 2030, because you cannot ship security fixes forever on top of libraries nobody maintains.

The outside world. Carriers and services retire old APIs whether your platform is maintained or not. FedEx killed its SOAP web services; OpenMage v20.18 ships a REST backend. Stock Magento 1 users simply lose FedEx rates. The same logic applies to image formats: AVIF support landed because modern sites need modern formats for Core Web Vitals, and no one at Adobe is going to add it to a platform they EOL'd in 2020.

What "supported" actually means here

Now the honest part, because nobody should read this and conclude OpenMage is equivalent to a vendor-backed platform.

OpenMage is maintained by volunteers. There is no SLA, no company to call when something breaks at 2am, no contractual patch timeline, no certification program. "Supported" means: an active repository, maintainers who review and merge fixes, security issues that get triaged and patched, and versioned releases you can pin. More than dead software gets, less than a commercial support contract.

For contrast: Adobe moved Magento 2 to a new security cadence in July 2026, isolated out-of-band patches per issue, with the first bulletin (APSB26-73) published on July 14, 2026. There is a vendor with a process and a legal name attached. OpenMage's process is public GitHub collaboration. Both produce patches. Only one gives you someone to point at contractually.

The practical mitigation for the no-SLA reality is the same as for any open source dependency: pin your versions, test upgrades on staging, and have a developer relationship (in-house or freelance) so patches actually get applied. The releases existing does not protect you. Applying them does.

The security reality for stores still on stock Magento 1

If you are on original, unpatched Magento 1 in 2026, here is your situation without any softening.

Your platform last received a vendor patch in June 2020. Every vulnerability found since then, including the classes of issues OpenMage fixed this year (deserialization, file upload, path traversal, XSS, open redirects, weak session IDs), exists in your codebase with no fix coming, ever. Magento 1 has been a documented card-skimming target for years: attackers know the stack, they have automated tooling for it, and abandoned stores are exactly the soft targets that tooling was built for.

Then there is PCI. I am not a QSA and this is not compliance advice, but the defensibility question is simple. When your acquirer asks how you handle security patching, "we apply the fork's releases, currently v20.18.0" is an answer. "No patches have existed since 2020" is an admission. After a breach, that difference decides whether you look negligent.

Many stores in this position have been lucky rather than safe, and owners usually find out which one they were when a customer's bank starts asking questions.

OpenMage, or Magento 2? An honest decision framework

OpenMage being alive does not mean it is right for everyone. Here is how the three realistic positions compare.

Stay on (or move to) OpenMage if: your store works, your margins do not justify a five-figure replatform, your customizations are deep and stable, and what you need is security patches and modern PHP rather than new capabilities. Plenty of profitable niche stores fit this description, and for them OpenMage buys years of safe operation at a fraction of replatform cost.

Replatform to Magento 2 if: you need things Magento 1's architecture will never do well (modern headless frontends, current checkout and payment ecosystems, actively developed extensions), you are growing into complexity, or you want a vendor-backed platform for compliance and procurement reasons. That is a bigger project, and I have written up how it actually works on my Magento 1 to 2 migration page. Be aware that Magento 2 has its own version treadmill: 2.4.6 reaches end of life in August 2026, and I covered what 2.4.6 stores should do about it separately. You are choosing ongoing upgrade work, not permanent peace.

What a Magento 1 to OpenMage migration actually involves

People hear "migration" and picture the Magento 1 to 2 ordeal: data migration tools, theme rebuilds, extension repurchases. An OpenMage migration is nothing like that. It is a core swap.

Your database stays exactly as it is. Same schema, same products, same customers, same order history, no data migration step at all. Your theme carries over because the theme system is unchanged. Most third-party extensions keep working because the extension format is unchanged. The real engineering effort is PHP compatibility: old local modules and crusty third-party code were written for PHP 5.x or 7.x, and getting them clean on PHP 8.1+ is where the hours go. Deprecated constructs, dynamic properties, that custom shipping module someone wrote in 2014.

My process, which I have productized as a fixed-price Magento 1 to OpenMage migration service, runs staging-first: build a staging copy on OpenMage and PHP 8.x, fix every compatibility issue there, test checkout and admin flows end to end, then cut over. Typical timeline is 2 to 3 weeks, the fixed fee starts at $2,499, and it includes 30 days of post-launch support because the long tail of PHP compatibility issues always includes one or two that only surface under real traffic.

After cutover, staying current is the easy part: OpenMage releases are drop-in upgrades within the 20.x line, and applying them is a routine maintenance task rather than a project.
