Best for: Experienced PHP/Magento developers building deep, code-level extensions for enterprise and B2B merchants.

Overview

Magento Marketplace (now under Adobe Commerce) distributes PHP-based extensions and themes for Magento Open Source and Adobe Commerce Cloud. Extensions integrate deeply with Magento's module system rather than a hosted API surface, making it one of the more code-intensive ecosystems to build for.

How to build & ship

  1. 1Register as a developer in the Adobe Commerce Marketplace Developer Portal
  2. 2Build the extension as a Composer-packaged PHP module following Adobe Commerce coding standards
  3. 3Integrate via service contracts/APIs and add tests (e.g. MFTF) for quality and compatibility
  4. 4Package the extension and submit it through the Extension Quality Program (EQP)
  5. 5Pass automated code/malware/plagiarism scans plus manual engineer QA, then publish
