Discover Micromegas CMS,
an open-source, reliable
content management system
Micromegas CMS is a completely free PHP framework and content management system. It's designed for small to medium-scale projects, with a focus on simplicity rather than a "jack-of-all-trades" approach.
It offers a clean starting point for websites and small web-app projects: it provides a solid, secure foundation while making very few assumptions about front-end design and technology. Micromegas is a modern framework, but it takes a "classic" client-server approach rather than a "JS webapp" one. Not every website is Facebook or Google... in fact, most aren't!
What makes Micromegas CMS different?
😊
Easy to use, accessible
The Micromegas CMS interface is designed to be easy for most people to use. It's clean and modern, with a focus on usability. Most users won't need any training — and they might like it even more if they're coming from a bigger CMS where they only ever used 10% of the features and were annoyed by the rest.

Friendly code, for and by humans
The simplicity of Micromegas CMS makes for a gentle learning curve. Its clean structure, based on tried-and-true design patterns, is easy to dive into — for experienced and new developers alike. The vast majority of the code was written by humans to be read by humans, no code generation or vibe-coding here!
🌱
An unbloated, eco-designed foundation
Micromegas CMS has a lean, solid foundation, avoiding the sometimes counter-productive "jack-of-all-trades" approach of other solutions. This allows the core code to be maintained for years with minimal oversight. It's also very small: less than 20 MB of code, unminified and uncompressed, with all dependencies included!
✨
Completely free
Micromegas CMS is completely free: you can modify it, copy it, or even resell it, with no intellectual-property restrictions or agreements. It's also very easy to tinker with, and it doesn't rely on any external services — which makes it ideal in an agency setting.
🤖
AI-ready
Micromegas CMS is ready to be augmented with AI, if you want it to be! This includes (optional) integration for Claude, DeepL and InpentAI... and all the abstraction needed so adding a new provider is trivial. Also, Micromegas CMS small codebase is perfect for AI agents to dive in!
🚀
Host anywhere
Micromegas CMS's self-contained architecture makes it easy to host and deploy. Any PHP 8.3+/MySQL hosting service will likely do the job! The lean architecture also translate to minimal requirements in term of disk space or memory needed.
