Cell inspection first
Open any cell into a full Monaco editor with auto-detected JSON / XML / SQL highlighting, format, live validation and F11 fullscreen. Not a popup with a textarea in it.

Features
A narrower scope than the IDE-style DB clients.
Most database GUIs are heavyweight Java suites or web dashboards that fight you the moment you open a JSON blob. HuginnDB picks a handful of things to do well, and the list stops there.
A real SQL editor
Schema-aware autocomplete, per-statement Run CodeLens, query history per connection that survives restarts, saved queries with tags. Ctrl+Enter and go.
Ctrl+Enterrun
Keyboard-first, minimal chrome
Dark by default. No nested toolbars, no popup soup. The shortcuts you already use in your text editor work here too, and the command palette covers the rest.
Ctrl+Kpalette
Credentials in the OS keychain
Passwords never touch disk in plaintext. Windows Credential Manager, libsecret on Linux, Keychain on macOS. The frontend never sees the connection string.

Multi-driver, one UI
PostgreSQL, MySQL, SQLite, MongoDB and SQL Server — each with its own connection dialog and the right defaults. Driver-specific quirks stay out of the way.

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