Poltergeist The ghost that keeps your builds fresh 👻
A universal file watcher with auto-rebuild for any language or build system
Poltergeist is an AI-friendly universal file-watcher that auto-detects any project and rebuilds them as soon as a file has been changed. Think npm run dev for native apps, with automatic configuration, notifications and a smart build queue. It stands on the shoulders of giants and fills the glue layer that's been missing.
Works on macOS, Linux, and Windows. Available as a standalone binary (no Node.js required) or npm package.
