Install ERRase
From zero to your first AI-fixed error in about two minutes.
Run the CLI
npx errase
Run this from your project root. ERRase automatically uses the current directory as the project path and boots a local WebSocket server on port 7891. Keep it running while you develop.
Install the Chrome Extension
ERRase is now on the Chrome Web Store — one click to install, no developer mode required.
Add to Chrome →Get a free Groq API key
https://console.groq.com
ERRase uses Groq's openai/gpt-oss-120b model for AI fix generation. Groq's free tier is generous enough for daily dev use — no credit card needed.
Add your key to the extension
Click the ERRase icon in Chrome → paste your Groq API key → click Save. The key is stored locally in your browser and never sent to ERRase servers.
Break something
Open your app, activate ERRase from the popup, and trigger a runtime error. ERRase detects it, maps it to your source file, and shows an AI-generated fix in the overlay. Click Apply Fix — done.
Requirements
- Node.js 18+— for the CLI
- Google Chrome— Chromium-based browsers work too
- React + Vite or webpack project— Next.js/Turbopack not yet supported
- Groq API key— free at console.groq.com
Known Limitations
Turbopack's source maps are sparse around HMR/refresh boilerplate, which can cause the CLI to confidently misattribute an error to the wrong file. This is a known, diagnosed issue — not a silent failure — and is why Next.js isn't supported yet. Separately, most AI-generated fixes are guard-clause-level patches rather than true root-cause rewrites, so always review the diff before clicking Apply.
