A Claude-native CMS for static sites. Fork of Pages CMS.

interleaved.app — hosted version, free to use.

Human edits content on their phone. Claude revises templates and styling. Both work on the same git repo, interleaved.

• Schema inference — drop markdown files in a folder, start editing. No .pages.yml required (still supported as opt-in override)
• External media storage — user uploads go to R2/S3/local with RIAPI/Imageflow query-string transforms. Theme assets stay in git
• Mobile-first UI — fixed bottom toolbar (avoids OS selection bubble), card-based content list, camera-to-upload pipeline
• Claude Code friendly — all content is plain markdown + YAML frontmatter. Zero proprietary formats. MCP server for media library access
• First-class source editing — CodeMirror is a peer of the rich text editor, not hidden behind a toggle

• GitHub App model for repo access
• PostgreSQL + Drizzle ORM (deploy on Railway, etc.)
• Next.js + React + shadcn/ui + TipTap + CodeMirror
• MIT license

• Node.js 20+
• PostgreSQL
• A GitHub App
