What is Widen?
Widen is a free, open-source native macOS Postgres GUI with AI agents that convert natural language questions into SQL. The agents search your schema, draft SQL, and verify it against PostgreSQL before execution, supporting both on-device (macOS 26+) and cloud modes via OpenRouter.
Widen pricing
Pricing model: Freemium
Free and MIT-licensed. Only potential cost is your own OpenRouter API key for cloud mode.
Widen pros
- Text-to-SQL with automatic verification against PostgreSQL before execution
- Completely free and open-source (MIT license) with privacy-first design—on-device mode keeps all data locally
- No backend, no account required, no analytics tracking
- Cloud mode supports any frontier model via your own OpenRouter API key
Widen cons
- Early release: no table-structure editor, plain table results only, no SQL syntax highlighting
- On-device mode requires macOS 26+ with Apple Silicon and Apple Intelligence; limited to SELECT queries
- PostgreSQL only—no MySQL or SQLite support yet
- Query results don't persist across restarts (though SQL transcripts are saved)
Frequently asked questions about Widen
Is it really free?
Yes, Widen is free and MIT-licensed. The only cost is if you use cloud mode with your own OpenRouter API key.
Does my data leave my Mac?
On-device mode keeps everything local with only network connection to Postgres. Cloud mode sends your question and relevant schema (never results) to your chosen model provider. Results always stay on your Mac.
How do the SQL agents work?
Agents search your schema for relevant tables, inspect columns and joins, draft SQL, and verify it against PostgreSQL in a read-only transaction before showing it. If it fails, the agent gets one repair attempt, then stops.
Can the AI modify my database?
Yes, it runs SELECT, INSERT, UPDATE and DELETE. Review generated SQL before running it. Table structure editing isn't implemented yet.
