errpulse

The error monitoring tool that runs with one command. Catch every error — frontend and backend — in a real-time dashboard. Zero config. Zero cost. One npx command.

Quick Start

npx errpulse
# => ErrPulse running at http://localhost:3800

Then add the SDKs to your app:

npm install @errpulse/node   # Backend: Node.js, Express, Next.js
npm install @errpulse/react  # Frontend: React

// Backend — zero-config auto-capture
import "@errpulse/node";

// Frontend — wrap your app
import { ErrPulseProvider } from "@errpulse/react";

<ErrPulseProvider endpoint="http://localhost:3800">
  <App />
</ErrPulseProvider>;

Open http://localhost:3800 — see all errors in real-time.
