Description
Asking an AI chatbot to "write me a SQL query" is easy, but pasting its answer straight into a production database is risky — the AI doesn't actually know your schema and can quietly get a query wrong. Widen tries to close that gap for people working directly with PostgreSQL: it's a native Mac app that discovers your actual database schema, then uses that to generate SQL from a plain-English question and checks the query is valid before you run it.
Widen is a native Swift macOS application built specifically as a Postgres GUI. Its text-to-SQL agent automatically discovers your database schema and generates SELECT, INSERT, UPDATE, or DELETE queries from natural-language questions, verifying each query against your actual PostgreSQL instance before execution rather than trusting the model blindly. On macOS 26 and later it can run the AI on-device; otherwise it uses cloud mode with your own API key. It's MIT-licensed, free, requires no account, has no backend server, and does no analytics tracking — everything runs locally against your database.
💬 Our review
The short version: Widen is a genuinely differentiated tool in a crowded field of Postgres GUIs, because the query-verification step means it's checking its own AI-generated SQL against your real schema before letting you run it — most "AI SQL assistant" features bolted onto other tools skip that step entirely.
Against DBeaver, DataGrip and pgAdmin — all mature, feature-rich, cross-platform database clients — Widen is narrower by design: it's Postgres-only, macOS-only, and built natively in Swift rather than as an Electron app, which typically means better performance and lower memory use on the platforms it does support. The privacy story (no account, no backend, no tracking, optional fully on-device AI) is a real advantage for developers wary of sending schema or query data to a cloud service. The trade-off is platform lock-in: if your team isn't all-Mac or you need MySQL/Oracle/SQL Server support, Widen simply isn't an option. Worth adopting if you're a Mac-based Postgres developer who wants AI-assisted query writing without the privacy trade-offs of cloud-only tools.
