Full Monaco editor for any cell — JSON / XML / SQL auto-detected, live validation, F11 fullscreen.

Schema-aware SQL editor — Ctrl+Enter to run, per-statement CodeLens, history that survives restarts.

_{Settings → MCP — point Claude Code, Claude Desktop, Cursor, or any MCP client at your real schema.}

Full feature list

• Multi-driver connection manager, each with a per-driver dialog and the right defaults.
• Schema explorer — tree of databases → tables/views/collections → columns (type badges, PK indicators) and indexes.
• Data browser — paginated, sortable, filterable grid (TanStack Table); inline edits routed through the backend with PK-based safety.
• View editor — create, edit, rename, drop, with a live preview grid and read-only DDL pane.
• Server-side security panel — read users/roles and privileges straight from the server, for every driver.
• Saved queries — a local library with name, description, tags.
• Multi-window — pop a connection's workspace, or a single tab, into its own OS window.
• Ten themes with a light/dark pair each, plus a visual colour editor grouped by surfaces/actions/status/borders.
• Resizable layout — horizontal and vertical splits, restored across restarts.

How it compares

No two of these tools are chasing the same thing, and all four below are genuinely good at what they do (DBeaver and HeidiSQL are two of the reasons HuginnDB looks the way it does — see Acknowledgements). Checked against each project's own docs/pricing pages as of writing (August 2026) — double-check the vendor's site for anything that's moved since.

Architecture

HuginnDB is split into two cooperating processes: a Tauri webview (React + TypeScript + Zustand + TanStack Table + Monaco) that never opens a database connection itself, and a Rust backend that owns every sqlx/mongodb/tiberius pool and resolves passwords from the OS keychain at the moment of use. The frontend calls a thin typed wrapper around Tauri's invoke and renders whatever the backend returns — connection strings never reach the webview. Full map of the code layout in CONTRIBUTING.md.

Tech stack: Tauri 2, React 18 + TypeScript (strict) + Vite, Tailwind + shadcn-style Radix primitives, Zustand, TanStack Table v8, self-hosted Monaco (no CDN), Rust with sqlx (Postgres/MySQL/SQLite), mongodb, tiberius (SQL Server), keyring, tokio.

Security model — single-user desktop tool; threat model is a curious local user or a hostile database operator, not a remote attacker. Full detail in SECURITY.md.

Prerequisites

Always use pnpm. Do not invoke npm or yarn — the lockfile is pnpm-only.

Windows — Visual Studio Build Tools 2022 (Desktop development with C++):

winget install --id Microsoft.VisualStudio.2022.BuildTools -e --override "--add Microsoft.VisualStudio.Workload.VCTools --includeRecommended --quiet --wait"

WebView2 is preinstalled on Windows 11; on Windows 10 install the Evergreen Bootstrapper.

Linux:

sudo apt install -y \
  libwebkit2gtk-4.1-dev build-essential curl wget file \
  libxdo-dev libssl-dev libayatana-appindicator3-dev \
  librsvg2-dev libsoup-3.0-dev libsecret-1-dev

Equivalent packages exist on Fedora, Arch, and Alpine — see the Tauri prerequisites.

macOS — xcode-select --install. Not a primary target yet; build should work, please file an issue if not.

git clone https://github.com/Alexfp28/huginnDB.git
cd huginnDB
pnpm install
pnpm tauri:dev          # dev mode with HMR — first run takes 5-10 min (Cargo compiles all drivers from scratch)
# or
pnpm tauri:build        # release bundle in src-tauri/target/release/bundle/
