Why Jam SQL Studio's Free Tier Stands Out
Get professional SQL development features without paying a cent or creating an account.
Unlimited Connections, All Engines
Connect to SQL Server, PostgreSQL, MySQL, MariaDB, and SQLite with no connection limits. Full IntelliSense and query execution for every database engine — no artificial restrictions in the free tier.
Free AI Agent Support
The only free SQL client with built-in AI agent support. The MCP server works with Claude Desktop, Claude Code, GitHub Copilot, and other AI tools — included in the free tier.
Free Charting
Create bar, line, pie, area, and scatter charts directly from query results. Export as SVG or PNG. Most competitors charge extra for charting features.
Cross-Platform, No Java Required
Works natively on Mac, Windows, and Linux. Unlike DBeaver, there's no Java runtime to install. Fast startup times and low memory usage across all platforms.
