Caelo

Any AI can build a homepage. Caelo is the open-source CMS for everything after. Point at your site in Live Edit and say what to change, or drive it from Claude Code over MCP. Every page is built from your own design system, so page fifty matches page one. The AI works in a draft, Lighthouse checks changes to how pages look, and by default only a person can publish. Visitors get static HTML, with no admin login on your public site. Bring your current site along. Self-hosted, free, MPL 2.0.
