fastgrid

fastgrid

A fast, stable, cross-platform database client written in Rust on GPUI Kit, with a built-in MCP server so external AI agents can query your databases safely.

Status: pre-alpha. SQLite, PostgreSQL, MySQL/MariaDB and SQL Server work end to end (browse, edit, structure, import/export, MCP), and M8 (polish and release) is in progress. See docs/roadmap.md and the docs index.

Goals

• Interaction modeled on TablePlus: tabs, schema tree, inline-editable grid, command palette.
• Features aiming at dbx-level coverage: SQL editor, structure editing, import/export.
• Performance and stability first: virtualized grid, streamed results, cancellable queries.
• MCP for external agents: fastgrid-cli mcp --stdio (and loopback HTTP), read-only by default, audited.
• macOS, Windows, Linux. Apache-2.0, free.

Phase 1 databases: SQLite, PostgreSQL, MySQL/MariaDB and SQL Server. All engines plug in through one driver abstraction (docs/driver-abstraction.md).

Layout

Crate	Role
fg-core	Domain types (connection, value, error). No IO.
fg-driver	Driver / Session traits + SQLite, PostgreSQL, MySQL/MariaDB, SQL Server
fg-crypto	Envelope encryption, password-protected files (no IO)
fg-store	Encrypted local store (connections, history, ...), migrations, backup/sync primitives
fg-sql	Statement splitting and classification, completion
fg-service	Pools, query tasks, metadata cache, policy; shared by GUI and MCP
fg-mcp	MCP server (stdio + local HTTP)
fg-cli	Headless binary fastgrid-cli
fg-app	GPUI desktop app fastgrid
