Ognom
Blocks writes to MongoDB connections you mark as production, free and open source
Ognom is a free, open-source MongoDB client built on Tauri and Rust that lets you mark a connection as production — once marked, it opens read-only every time, enforced at the API layer so no shell command, shortcut, or $out stage can write around it. It also diffs two collections by _id with a field-level view and one-click sync, and can copy whole collections, indexes included, between servers in streamed batches. Credentials are AES-256-GCM encrypted, with no telemetry, no account, and no AI features — 'everything is a query, a table, a document or an index.'
What holds up
- +Production connections open read-only by default, enforced at the API layer — no shortcut bypasses it
- +Free and open source under MIT, with no account, sign-in, or telemetry
- +Diffs two collections by _id with a field-level view, then lets you sync or delete strays selectively
- +Credentials are AES-256-GCM encrypted, with an option to move the key into your OS keychain
Mind the limits
- −MongoDB only — no support for Postgres, MySQL, or other databases
