OpenMage, also known as OpenMage LTS or MageLTS, is a community-maintained, backward-compatible fork of Magento 1 Community Edition (Magento CE).

The project was created to continue the development and maintenance of Magento 1 after its official end of life. It provides an upgrade path for existing Magento 1 stores while preserving the familiar Magento 1 architecture, extensions, themes, and administration interface.

OpenMage continues to receive:

  • security fixes and vulnerability patches;
  • bug fixes and stability improvements;
  • support for modern PHP versions;
  • performance and compatibility improvements;
  • community-maintained updates to the original Magento 1 codebase.

LTS stands for Long Term Support.

For stores still running Magento 1, migrating to OpenMage is usually a significantly smaller change than migrating to Magento 2 because the existing Magento 1 codebase can largely be retained. However, custom extensions, themes, core modifications, and compatibility with newer PHP versions should be reviewed before upgrading.

We can upgrade Magento 1.x stores to the latest stable OpenMage LTS release, including compatibility checks for installed extensions, custom code, themes, and PHP versions. Select OpenMage LTS in our upgrade or patch installation request form.
