Download BsonJet
BsonJet is a desktop MongoDB client from Letsnet s.r.o. for Windows, macOS and Linux. It moves values, documents, collections and databases between servers using raw BSON with indexes. Network drops do not restart transfers. Backups are mongodump-compatible and can be encrypted with AES-256.
The application shows replica set health with live charts and renders sub-documents as table rows. A mongosh-compatible shell, an AI assistant on the user's own key and one-click connection import from Compass, Studio 3T, Robo 3T, NoSQLBooster, DataGrip, DbGate and DBeaver are included.
BsonJet stays responsive on large collections and databases with tens of thousands of collections. Personal use is free with the full version and no registration. A one-time Pro license for work covers every update of the major version. The program is written in C# on .NET.
