Magento 2 is Adobe's open-source PHP e-commerce platform, now officially called Magento Open Source. It's the self-hosted tier below Adobe Commerce — suitable for developers who need full control over a mature, feature-complete storefront without the enterprise licensing cost.
The module system is genuinely well-designed: each module is self-contained with its own DI config, routes, schema declarations, and i18n, which makes large teams manageable. The declarative schema approach (db_schema.xml) is a real improvement over the old install/upgrade script chaos. MFTF (Magento Functional Testing Framework) gives you a structured way to write browser-level acceptance tests, which most PHP e-commerce platforms don't bother with. The contributor process is unusually disciplined for an OSS project — automated PHPCS gates, named maintainers, and a structured PR template.
The DI container and plugin (interceptor) system are notoriously slow — a cold page load hits hundreds of generated proxy and interceptor classes before serving anything. Adobe has been systematically defunding the open-source edition since the Commerce acquisition: features land in Commerce first (sometimes only), and the open-source roadmap is opaque at best. The CLA requirement (Adobe CLA, not a standard OSL-3.0 contributor agreement) is a turnoff for serious contributors who don't want to sign IP rights over to a corporation. Local development is genuinely painful — the recommended stack involves Docker, Varnish, Redis, Elasticsearch or OpenSearch, and a specific PHP version, and getting all of that running without composer conflicts is a rite of passage, not a quick start.
