Built for the hard part of MongoDB

Not another row viewer. mongoui works on debugging, optimizing, and cleaning.

Smart Scan

One click runs a full health pass — indexes, storage, duplicates, schema — and surfaces exactly what needs attention. Green when you're clear, specific when you're not.

Query Optimizer

Real explain() data, read back to you in plain English. See COLLSCANs, documents examined vs. returned, and the precise index that fixes it.

Safe Cleanup

Every cleanup is a dry-run first: see the exact before/after counts, then apply behind a gate. Snapshots mean any applied change can be undone with one click.

Index & Storage insight

See which indexes earn their keep and which just cost writes, plus where storage actually goes — collection by collection, with reclaimable space called out.

Duplicate finder

Define what “the same” means for your data and mongoui groups the duplicates, shows you the clusters, and lets you resolve them safely — never a blind delete.

Schema doctor

Sample a collection and get a clear read on field shapes, type drift, and missing fields — the mismatches that quietly break queries, found before they bite.

Full documents stay on your machine.

The engine talks directly to MongoDB. Full documents and MongoDB credentials are never sent to mongoui. AI starts in Local mode; explicit AI actions send only the disclosed authored and structural context directly to your selected provider, without a mongoui proxy.
