Data Peek is a lightweight, keyboard-first SQL database client for Windows, macOS, and Linux. It connects to PostgreSQL, MySQL, SQL Server, SQLite, and ClickHouse databases through a streamlined interface. Its Monaco editor provides schema-aware autocompletion, saved queries, and reusable SQL notebooks. Users can edit records, inspect relationships, import datasets, and export query results in multiple formats. Watch Mode continuously refreshes read-only queries, while Time Machine compares historical results. Performance tools visualize execution plans, identify slow queries, and diagnose schema problems. An AI assistant generates SQL from natural language and integrates with external coding agents through MCP. Credentials remain protected by the operating system's keychain, with no mandatory account or telemetry.
