Open Source Rust SQL Clients

DBFlux is an open-source, keyboard-first database client built with Rust and GPUI for Windows, macOS, and Linux. It provides a unified workspace for relational databases, NoSQL systems, and cloud data services. Supported backends include PostgreSQL, MySQL, SQLite, MongoDB, Redis, DynamoDB, SQL Server, and others. A multi-tab SQL editor offers syntax highlighting, query execution, and persistent sessions. Users can browse schemas, inspect records, filter tables, and edit supported data types. Integrated dashboards, charts, and database metrics help visualize information. Connection options include SSH tunneling, TLS, and AWS authentication. A fuzzy-search command palette, scripting hooks, audit tools, and extensible RPC drivers support efficient database administration and development.

DBDelve is a free, open-source database client designed for fast, resource-efficient data management. Built with Rust and GPUI, it provides a native interface without Electron or Java dependencies. The application supports PostgreSQL, MySQL, MariaDB, SQLite, MongoDB, Redis, SQL Server, and other database engines. Users can browse large tables, execute SQL queries, and modify records through an interactive editor. It provides schema-aware autocompletion, query execution plans, and customizable column layouts. Database connections can be organized into projects with configurable access permissions. Additional capabilities include SSH tunneling, data importing, and importing connections from other database tools. Available for Windows, macOS, and Linux, DBDelve focuses on responsive database exploration.

BarSQL is a free, open-source desktop SQL client for PostgreSQL, MySQL, MariaDB, SQL Server, ClickHouse, Turso/libSQL and SQLite. It's a native app written in Rust and drawn on the GPU, with no account, no cloud and no telemetry. Everything it keeps lives in one portable folder next to the app. Features include schema-aware autocomplete, multiple cursors, an editable results grid, quick charts, a query plan viewer, ER diagrams, a table structure editor, schema compare with sync scripts, CSV import, export, SSH tunnels, a read-only mode, and an MCP server so AI assistants can query the databases you allow.

Turso is an in-process SQL database written in Rust and designed to stay compatible with SQLite. It supports SQLite’s SQL dialect, file formats, and C API while adding newer database capabilities. The project is currently in beta, so it is best used with care and proper backups for production data. Turso includes support for concurrent writes through MVCC, change data capture, and faster schema management. It offers bindings and integrations across languages such as Rust, JavaScript, Go, Python, Java, .NET, and WebAssembly. The database also includes vector support, asynchronous Linux I/O with io_uring, and a built-in MCP server that lets AI assistants inspect and modify databases through structured tools.
