Mongrel is a desktop database systems workbench that unifies 30+ database engines, terminals, file transfer, containers, Kubernetes, and an API client in one native app for Windows, macOS, and Linux.
Query PostgreSQL, MySQL, MongoDB, SQL Server, Oracle, Redis, ClickHouse, Snowflake, BigQuery, and more in native SQL or engine dialects. Edit data inline, drill through foreign keys, run EXPLAIN plans, design schemas on a visual ER canvas, sync data between databases, and schedule encrypted backups. Built-in SSH/Mosh/Telnet/Serial terminals, SFTP/SCP file transfer, Docker and Podman management, Kubernetes operations, and an HTTP/GraphQL/WebSocket/gRPC client replace a stack of tools.
An opt-in AI assistant supports OpenAI-compatible, Anthropic, and Gemini providers, with keys in your OS keychain and writes always approval-gated. Mongrel is local-first: your queries, data, and logs never leave your machine. All plans include every feature; start with a 7-day trial, no card required.
