Define once
Fields drive TypeScript inference, validation, editor controls, and canonical files.
Files-first CMS for Next.js
Typed content, plain files.
Pith gives Next.js a typed content layer and an editor — content stays in your repository.
pnpm add @pith-cms/cli@latest pnpm pith init
What it does
The useful parts. Nothing hidden.
Keep files portable
Use ordered JSON or Markdown frontmatter. Change storage without changing content.
Edit with a boundary
Protect mutations, require revisions, preview unsaved work, and surface conflicts.
Publish your way
Write to a persistent volume, commit directly to GitHub, or create a pull request.
Pith editor
Write where your content lives.

Description
A Pith site.
A typed content editor that reads and writes directly to your repository files. Define collections once — the editor generates the form. No database, no migration, no external service.
Pith CLI
Scaffold and manage from the terminal.
$ pnpm pith init
✓ Scaffolded pith.config.ts, src/lib/pith.ts, editor routes
✓ Installed dependencies
$ pnpm pith collection add
> Collection name: posts
> Fields: title, slug, publishedAt, body
✓ Added "Posts" collection and created content/posts/
$ pnpm pith content check
✓ All content entries are valid.
Scaffold a new project, define collections interactively, and validate every entry against your schema — all from the terminal. No running services, no dashboards, just real files.
