Three to know

The ones we get asked about most.

A few tools on 1tt.dev have outgrown their category. These are the big ones — built as full studios for work you'd otherwise bounce between several apps to do.

Data · SQL

Database Studio

A full Postgres client in the browser. Connect, run queries, browse schemas, inspect rows, tunnel through the CLI to prod — no desktop install, no driver hell, no accidental writes to prod.
