ErrPulseError monitoring that runs with one command

Zero-config, local-first error tracking for Node.js and React applications

⚡

One Command

Run npx errpulse and you have a full error monitoring server with a real-time dashboard. No accounts, no config files, no cloud.

🎯

Catches Everything

Uncaught exceptions, unhandled rejections, HTTP errors, React crashes, failed fetches, console.error, memory warnings — all captured automatically.

📊

Real-Time Dashboard

Health score, error timeline, filterable error list, plain-English explanations, stack trace viewer, and HTTP request log — all updating live via WebSocket.

🏗️

Multi-Project Support

Track errors from multiple apps in one place. Each SDK sends a projectId, and the dashboard filters all views per project.
