One editor card per stage, 24 operators with starter snippets. Disable a stage, run to any point, and see doc counts, drop-off and timing per stage.
MongoDB,
beautifully.
The free, open-source client that knows when a connection is production.
01
Native and light
A Rust core and your OS webview. A tiny binary that starts fast and stays out of the way.
02
Private by design
No account, no sign-in, no telemetry. Your queries go to your server and nowhere else.
03
Encrypted at rest
Credentials are AES-256-GCM encrypted; one toggle moves the key into your OS keychain.
04
No AI, no fluff
A focused console for developers. Everything is a query, a table, a document or an index.
The console
Powerful where it counts,
quiet everywhere else.
Ognom 2.0 is a complete redesign on one token contract. Five things it does that your current client probably does not - each one exactly as it ships.
01 Safety
Knows what production is.
Mark a connection as production and it opens read-only, every time. The block is enforced in one place - the API layer - so no menu, shortcut, shell statement or $out stage can write around it.
- Edit mode is an explicit, session-scoped switch in the status bar - and Ognom asks first
- A red tag on the rail keeps the blast radius visible at all times
- A plain read-only mode for browsing any server without fear
02 Data tools
Diff two collections.
Then sync them.
Compare any collection against another database - or another server - by _id, with a live progress bar. Every bucket counted, every changed field shown side by side.
- Copy missing documents to the target, overwrite changed ones, or delete strays - each behind its own confirmation
- Changed rows expand into a field-level diff table
- The diff re-runs automatically after every sync
03 Data tools
Move a collection anywhere.
Copy a collection to another database or any open connection - staging to local, cluster to cluster - streamed in batches with live progress. Bring the indexes along with one checkbox.
- An optional filter copies matching documents only
- Target database is free text - new databases are allowed
- Cancel any time; Ognom reports exactly how far it got
- One-click duplicate in the same database, with a safe _backup default
04 Safety
Destructive actions are slow on purpose.
Dropping a collection states exactly what it removes, requires typing the collection's name, and offers a BSON dump first. If you cancel the backup, the drop is cancelled too.
- Multi-document deletes offer an optional JSON export first
- Bulk delete refuses an empty filter outright - it will not wipe a collection by accident
- Affected-count previews with sample _ids before every bulk write
05 Querying
A query never hides its cost.
Matched count, timing and the winning plan sit right above the input. And the dock is a real editor: multi-line, auto-closing, with completions sampled from your actual schema.
- Find, Aggregate and Shell share one transport
- /regex/i, new Date() and ObjectId() literals just work
- Explain names the index a collection scan is begging for - one click creates it
- Save a query with its sort and projection, per collection
Appearance
Eight themes. Three densities.
One token contract.
A theme is one CSS block of the same 30 tokens - surfaces, hairlines, text, accent, semantics, syntax. Nothing in the component layer knows which theme is on. This very console is live - press a swatch.
Plus a ninth option: Follow OS. In the app, ⌘⇧T cycles themes and density is a separate axis.
And the rest
Everything is a query, a table,
a document or an index.
A real shell
mongosh-flavoured syntax with history and completions. Unbounded finds are capped, updates require operator documents - guard rails, not training wheels.
Schema analysis
Sample up to 10,000 documents: types per field, mixed-type percentages, example values and a coverage bar for every path.
Indexes that confess
Unused indexes get called out with zero-ops stats. Six create templates from compound to TTL, with a live preview of the exact createIndex call.
Import and export
JSON, NDJSON, CSV and mongodump-compatible BSON, streamed with live progress and cancel. Export honours the current filter and sort.
Find anything
⌘K jumps to any collection, database, connection or action. Fuzzy matching, live pills, open in a new tab with ⌘⏎.
Workspaces
Every connection is a colour-tagged tile on the rail. Keep several live at once; each remembers its tabs, picker and query state between launches.
Server operations
Live currentOp with kill, a per-database profiler with COLLSCAN pills, and 2-second server metrics. Missing privileges degrade into plain-English notices.
Interface builder
Turn a sampled schema into TypeScript interfaces or Zod schemas. Split nested objects into their own interfaces, pick ObjectId or string per field, and copy the result.
