Widen

About Widen

Widen is a free, open-source, native macOS Postgres GUI whose text-to-SQL is built around verification rather than generation. The usual approach dumps an entire schema into one prompt and hopes; Widen's agents instead search the schema, call only the tables they need, draft the SQL with an explanation and a confidence score, and then verify it against PostgreSQL before it ever reaches your editor. If the statement does not parse, the agent gets exactly one repair attempt and then stops — a deliberate bound that prevents the failure mode where an agent burns tokens looping on a query it cannot fix. Nothing runs without review: generated SQL lands in an editable editor with a review-before-run step, so the model proposes and you execute. The AI can run on-device on macOS 26 and later, or against a cloud model, and no account is required either way. It is written in Swift as a genuine native app rather than an Electron shell, ships as a 15 MB download, and is MIT licensed with the source on GitHub. For anyone who wants a fast Postgres client and is wary of pasting their production schema into a chat window, the combination of local execution, schema-search rather than schema-dump, and pre-run verification is a much more careful design than the category norm.
