What it is

DataZen is a free, open-source desktop workspace for database querying, analysis, visualization, and automation. It includes PostgreSQL, MySQL/MariaDB, SQLite, and Redis support by default; optional drivers cover MongoDB, ClickHouse, DuckDB, SQL Server, and other databases. Its SQL editor offers schema-aware autocomplete, syntax highlighting, multi-statement execution, query history, favorites, and configurable result limits. Results can be displayed as line, bar, pie, scatter, or area charts and exported as PNG or SVG. DataZen also supports SQL backups, row-level synchronization, transfers between different database types, and controlled schema deployment. YAML workflows can combine queries, AI steps, conditions, and loops across connections. AI can use OpenAI, Anthropic, DeepSeek, Ollama, or custom compatible endpoints; the app also provides an MCP server and client. Database browsing and queries work offline, but AI requires an internet connection. Passwords are encrypted with AES-256-GCM, and there is no cloud sync or team server. The Free plan is free.
