Step by step

Evaluate MQLens with a real task

  1. Connect to a test database

    Set up your connection and check authentication, TLS, and SSH requirements before moving any production work.

  2. Run a familiar query

    Browse the result, build an aggregation, and inspect an explain plan. Compare usability with the tool you already know.

  3. Check your requirements

    Start with a test database and recreate the connection settings in MQLens. Check your authentication, TLS and SSH setup, then validate your saved queries. Automatic import of Robo 3T connection profiles is not advertised.
