Show HN: Deeb – a lightweight embedded JSON database written in Rust

I’ve been working on Deeb — a tiny embedded database that stores your data as JSON files and behaves like an ACID-ish transactional database. It’s written in Rust and designed for small apps, side projects, experiments, or dev tools where spinning up Postgres or Mongo is overkill.

It’s inspired by the flexibility of MongoDB and the simplicity of SQLite, but stores everything in plain JSON. That means you can open, inspect, and edit your data manually — or use the API to query and mutate it with transactions, associations, and nested queries.

I just launched a new docs site and opened up a Discord community for discussion/feedback.

Some of the early use cases people have shown interest in: • Local-first apps • Simple tooling dashboards • Quick mock APIs • Portable experiment storage • Drop-in database for internal dev tools

Would love to hear your thoughts — critiques welcome. Always looking to make this thing sharper.
