Mature, git-based; heavier setup, dated DX. JustJSON takes a different path: your content is plain JSON in your own repo — no account, no server, no API key — and you start in one command.
| Tool | Account | Server / DB | API key | Local-first | Typed output | Best for |
|---|---|---|---|---|---|---|
| JustJSON Local, file-based — needs no backend at all. | None | None — files on disk | None | Always (fully local) | types.ts + Astro collections | Devs who want content with zero backend |
| Decap (Netlify CMS) Mature, git-based; heavier setup, dated DX. | None (git) — needs auth setup | None, but an OAuth broker is required | Git provider auth | Partial | No | Existing Netlify / git sites |
A fair-use summary of publicly documented behaviour, compiled 2026. Decap (Netlify CMS) is a solid project — tell us if anything reads wrong. See the full comparison across all of them.
