Document-first
Store, query, and stream JSON documents without running a separate server. JSONVault keeps everything in inspectable files inside your repository.
Powerful tooling
Schemas, hooks, SQL with joins, migrations, a durable change log, and a CLI come included. No plugins required.
Ready for production
Field-level encryption, TTL indexes, partitioned storage, and transactions make it easy to build reliable workflows.
What does a JSONVault app look like?
A few lines let you open a database, attach a schema, and run queries using either filter objects or SQL with joins.

JSONVault keeps data in human-readable JSON, so snapshots, migrations, and audits all live alongside your application. No server to manage, no hidden state.
