Fosta Studio is a database client written in Rust: lightweight, fast, with an installer of only 9 MB. An app that replaces dozens of tools you are currently using to work with databases.

• Integrates AI agent: understands your database structure, writes and explains queries, uses your API key (OpenAI, Claude, Gemini, Ollama…). Supports MCP for Claude Code, Cursor queries databases securely, every write command must be approved by you.
• Multiple workspaces: each project or client has its own separate space, with its own connection and security rules. The Production workspace is read-only by default, preventing accidental modifications to real data.
• Automatic tunneling: SSH tunnel and port-forward are declared once, automatically activated when connecting, automatically deactivated when not in use.
• One app for 11 databases: MySQL, PostgreSQL, SQL Server, MongoDB, Redis, Elasticsearch, ClickHouse, Oracle…

Free, open-source (GPL-3.0), no account required, no data collection. Runs on Windows; macOS and Linux can use the web version via Docker.
