Show HN: Vaultbase – a self-hosted back end in a single binary

An independent developer released Vaultbase, an MIT-licensed self-hosted backend that runs from a single binary and bundles a database with a REST API, sign-in, realtime, files, server-side hooks and jobs on SQLite or Postgres. The project has shipped 80 releases since May 2026 and is backed by more than 2,800 tests, though it remains pre-1.0 and has not had an outside security audit; the developer said security reviews are run with Claude and that Claude also assisted with the codebase, documentation and fact-checking. A demo is available at demo.vaultbase.sh and resets every hour.

One binary to run and you have a full backend at your fingertips: a database with a REST API, sign-in, realtime, files, server-side hooks and jobs, on SQLite or Postgres. It's MIT licensed. You can try the demo at https://demo.vaultbase.sh (the login is filled in, and it resets every hour). I built it to ship fast. I always tend to write the same logic for any new project, whether it's a side project or a small to medium project for a client. I wanted something my friends and I could work with fast, try new things with, and that's easy to use. Then it became something I really wanted to work on and make as complete as I can for any type of backend. As of writing this post it has 80 releases since May this year and is backed by more than 2,800 tests. I also run security reviews with Claude and fix what they find. It hasn't had an outside audit yet. It was built with the help of Claude, from the codebase to the documentation and fact-checking it against the code. Claude helped speed up the pace, find bugs, and write tests. Vaultbase is pre-1.0, so expect some bugs and issues here and there. I'm working hard to fix each and every one of them. Thank you for taking the time to read this. I'd really appreciate any feedback, even if you didn't like Vaultbase. The demo is yours to try, and it's two commands to run locally.
