An open-source CMS

Finally, a CMS that gets out of your way.

Modern PHP. Flat-file flexibility. Ready for the AI era. No plugin headache.

Get started Star on GitHub MIT, free forever

Powering documentation, marketing pages, and content-driven apps for teams who value clean code.

What you get

Six things Pushword does well.

AI-native editing: Flat-file mode lets Cursor, Claude, and Copilot edit your Markdown directly — and a REST API takes it further, letting agents drive a live site.
Cutting-edge stack: PHP 8.4, Symfony 8, Doctrine 3, Tailwind 4. Modern features, strict typing, PHPStan enforced.
SEO-first design: Built by an SEO consultant. Meta, schema, dead-link detection, internal linking, OpenGraph: all built in.
Multi-site and i18n native: No WPML. No plugins. Multiple sites and languages live in the core.
Deploy anywhere: Static generation is built in. GitHub Pages, Netlify, Vercel, or any PHP host.
Page versioning: Track changes, compare versions side by side, restore with confidence. Full history.

Beyond flat-file

Flat files were only the start.

Flat files let an AI edit Markdown on your laptop. But your content lives on a live, multi-site instance — so we built a REST API that mirrors the whole admin (pages, media, redirections, even dead-link scans) and is designed, field by field, for agents to drive. Point Claude Code at it and editors run advanced content operations in plain language, straight to production — safely.

Self-describing: GET /api/docs returns a live OpenAPI 3.1 spec built from the controllers themselves. An agent discovers every route and field before it authenticates — no docs to ship, never out of date.
Token-efficient edits: PATCH takes anchored find/replace, so an agent sends only the slice it changed — not the whole page. Each anchor must match exactly once, or the write is refused: a loud error beats a silent wrong edit.
Safe concurrency: Every page carries a revision; writes send If-Match. An agent and a human can't clobber each other — a stale write returns 409 with the fresh page to rebase on.
Nothing ships by accident: Edits stage as drafts while the live site keeps serving. ROLE_EDITOR gates every token, and the Version extension diffs each revision before you publish.

One anchored edit — not the whole page

PATCH /api/page/example.com/pricing

{ "edits": [
    { "find": "From 90€", "replace": "From 120€" }
] }

In production today

Real brand sites are edited entirely through this API. Marketing teams open Claude Code, type what they want in plain French or English, and every save syncs to production with optimistic locking — always staged as a draft until a human publishes.
