How to browse and query a database from the terminal with Masume

Open a database in a keyboard-driven client and run SQL with completion and query plans.

Short answer: Run brew install masumedb/tap/masume; then run masume ./notes.db for a SQLite file, or masume postgres://[email protected]:5432/shop for a URL; Press ? to see the keys and Ctrl+K to open the command palette. All steps.

Who it is forA developer or analyst who needs to look at tables and run queries on a database without opening a GUI tool.

The problemSwitching between a browser tool, a shell, and docs slows down quick checks on a database.

The outcomeYou connect to a database, browse its objects, and run a query with results shown in a grid.

What you need first

  • A terminal on macOS, Linux, or Windows
  • A database you can reach, or a local SQLite file
  • One install method: Homebrew, npm, Go 1.27 or later, or a release package

Steps

  1. Run brew install masumedb/tap/masume
  2. Run masume ./notes.db for a SQLite file, or masume postgres://[email protected]:5432/shop for a URL
  3. Press ? to see the keys and Ctrl+K to open the command palette
  4. Write a query in the editor and run it, then sort or filter the grid

Prompt for your agent

In the masume repo, open the database at <target> with `masume <target>` and run `select count(*) from <table>`. Expected output: a single row with a count. Verify the count matches the table size reported by the database.

Caveat. The README lists the supported engines, but a given engine may have limits; check docs/engines.md before relying on a specific feature.
