TabEngine

TabEngine is a desktop guitar tab player for Windows, macOS, and Linux. Drop in a Guitar Pro file (GP3, GP4, GP5, or GPX) and it renders synced tablature and standard notation, powered by the alphaTab engine. It includes a real mixer with per-track volume, mute, solo, and pan; loop sections; a metronome; and tempo shifting for slowing down tricky parts. Everything works fully offline once you have a file loaded, and if you don't have one locally, TabEngine can search and pull tabs directly from Songsterr without leaving the app. It was built as a direct reaction to Songsterr locking previously free, client-side-only features behind a paywall. TabEngine is licensed under GPLv3, meaning it's free now and permanently — no premium tier, no paywalled updates — and any derivative work has to stay free too. The app is built with Svelte 4 + TypeScript on the frontend (rendering/audio via alphaTab) and Rust via Tauri 2 on the backend, so it ships as a lightweight native app rather than an Electron bundle. Note: This is an early-stage/solo project — functional but still rough in places, and prebuilt binaries are unsigned (so Windows SmartScreen and macOS Gatekeeper will flag it on first run).
