AlchemyCMS: open-source CMS

About AlchemyCMS

Alchemy is an open-source CMS engine written in Ruby on Rails, built around a component-based approach to web content. It can be used as a traditional server-side rendered CMS or as a headless CMS, and it plugs into existing Rails applications as an engine.

Features listed by the project include templating that separates content from markup, a RESTful API, an admin interface with live preview, multi-language and multi-domain support, page versioning, SEO-friendly URLs, user access control, a built-in contact form mailer, attachments and downloads, on-the-fly image cropping and resizing, flexible caching, and extension through Rails engines.

AlchemyCMS is licensed under BSD-3-Clause and can be hosted on any server that supports Ruby on Rails, a SQL database and ImageMagick. A public demo is available, and the project maintains stable branches matched to different Rails versions, with the main branch intended for development rather than production.
