What is it?

Éclair CMS is a small content management system written in plain PHP 8.1+, with no database, no Composer dependencies and no plugin ecosystem. Content is stored as protected files, and public pages are served from a static cache, so it runs on ordinary Apache or LiteSpeed shared hosting. The project is aimed at freelancers, craftspeople and small businesses that want a fast, low-maintenance website.

The CMS includes SEO features such as real-time page scoring, JSON-LD structured data, sitemaps with hreflang, RSS and 301 redirects, along with GEO features for AI answer engines: llms.txt, a Markdown version of each page, and per-bot robots policies. An optional product mode links each item to a Stripe, PayPal or Revolut Business payment link rather than running a cart. An AI assistant can draft articles and images using the user's own Claude or ChatGPT API keys, and an MCP connector lets Claude or ChatGPT work on the site with the user's subscription, with publishing and deletion kept under manual control.

The project is licensed under AGPL-3.0, and updates are signed with Ed25519 and verified before installation.
