Why HuginnDB

Made for people
who never leave
the keyboard.

Most database GUIs are heavyweight Java IDEs or web dashboards that fight you the moment you need to read a 50 KB JSON blob inside a column. HuginnDB picks a narrower scope and does it properly. Everything below is in the shipped app.

  • Keyboard-first

    Minimal chrome, no nested toolbars, no popup soup. Run a query with Ctrl+Enter and keep typing.

    Ctrl+Enter

  • A real SQL editor

    Monaco — the editor from VS Code, self-hosted with no CDN — with schema-aware autocomplete, a per-statement Run CodeLens and history that survives restarts.

    Autocomplete

  • Monaco in every cell

    Pop any cell into a full editor with JSON, XML and SQL auto-detected, format and beautify, live JSON validation and an F11 fullscreen toggle.

  • Built-in MCP server

    A headless stdio server so AI agents can browse schemas and run queries against your real databases. Read-only by default; writes are opt-in per connection and audited.

  • Credentials in the keychain

    Passwords go to the OS keychain — Windows Credential Manager or libsecret. The on-disk profile holds only host, port, database, username and an SSL toggle.

  • Five engines, one UI

    PostgreSQL, MySQL, SQLite, MongoDB and SQL Server, each with a per-driver connection dialog, side by side in the same app.

    5 drivers

  • Visual ALTER TABLE

    Add, rename and drop columns, change types, edit primary keys, foreign keys and indexes — previewed as the exact DDL that will run before it runs.

  • Native, not a browser tab

    Rust and Tauri 2 under the hood. The frontend never opens a database connection; every pool lives in the Rust process, and passwords resolve from the keychain at the moment of use.

    Rust + Tauri 2

  • Themes that stay yours

    Five built-in presets plus a visual colour editor. Editing a preset forks it into a new custom theme, so the originals stay pristine.

What is not done yet

The project is stable and has followed SemVer since 1.0, but a comparison page that only flatters itself is marketing. These are the current gaps, straight from the repo:

  • macOS builds are unverified — there is no published macOS binary, only build-from-source.
  • Windows binaries are not code-signed yet, so SmartScreen shows a warning on first launch.
  • No automated frontend tests yet.
  • No arm64 build, no .rpm, and no Flatpak, Snap or AUR packaging.
