Monghoul

v1.14.1 · 38 MB · Windows, macOS, Linux

Query and manage MongoDB from one workspace

Suggestions from your own data, related documents one click away after a scan, and query plans that name the index a slow query needs. Each part below shows the real screen. Most of it is free; charts, cluster monitoring, user management and AI access need Pro.
