No. Download, install, and use — no signup required.
Your database data and credentials stay on your machine — DataZen runs no cloud service, so nothing passes through our servers. Only when you use AI features are schema and query context sent to the AI provider you configure (OpenAI / Anthropic / DeepSeek / custom endpoint).
Yes, bring your own key. Regular database queries and browsing work without one.
Yes. DataZen is GPLv3-licensed: internal business use is fine. If you distribute DataZen itself or a modified version, you must make the corresponding source available under GPLv3. See the GPLv3 license for embedding/redistribution details.
PostgreSQL, MySQL / MariaDB, SQLite, and Redis are built in. Additional databases (Presto, Trino, ClickHouse, and more) are available via plugins.
Yes — .deb, .rpm, and AppImage for x86_64.
Yes. You can check for updates or toggle auto-update in Settings.
Yes. All database queries and browsing work fully offline. AI features require an internet connection to your configured provider, but the app itself never phones home.
Click "New Connection" in the sidebar, choose your database type, and enter host / port / credentials. DataZen supports SSL, SSH tunnels, and multi-database sessions for PostgreSQL and MySQL.
Connection configs can be exported and imported, but DataZen is a local desktop app — there is no cloud sync or team server. For shared access, use the built-in MCP server to expose databases to AI agents.
