Show HN: SonicJS – open-source headless CMS built on Cloudflare Workers
I built SonicJS because I wanted a headless CMS that runs natively on edge infrastructure without managing servers.
Key details:
- Runs on Cloudflare Workers (free tier works)
- Uses D1 (SQLite) for storage
- Built with Hono.js and Drizzle ORM
- REST and GraphQL APIs
- Admin UI included
- TypeScript throughout
The main goal was keeping it lightweight - the whole thing is under 150KB. No cold starts since it's on edge.
Been working on this for a while and recently added AI-assisted content schema generation which has been fun to experiment with.
Happy to answer questions about the architecture or Cloudflare Workers gotchas.
