Full MongoDB power at $0.
A free Studio 3T alternative.
Studio 3T is a commercial, Java-based MongoDB GUI that demands a paid subscription. MQLens gives you the same professional depth — aggregation pipelines with visual explain plans, every auth mechanism, TLS/SSH/SOCKS5, bulk edit, schema analysis, GridFS, an embedded mongosh, and an AI query assistant — for $0. No subscription, no licence key, no Electron. Native Tauri/Rust, 14 MB, Apache-2.0, free forever.
