Sentry Has a Free Error Tracking Platform — Find and Fix Bugs Before Users Report Them

#debugging #monitoring #devtools #javascript

Sentry is the industry-standard error tracking platform for developers.

What You Get for Free

  • 5,000 errors/month — free developer tier
  • Stack traces — with source maps, deobfuscation
  • Breadcrumbs — what happened before the error (clicks, API calls, console logs)
  • Session replay — video replay of what the user did
  • Performance — transaction tracing, slow query detection
  • Release tracking — which deploy introduced the bug
  • Alerts — Slack, email, PagerDuty notifications
  • SDKs — JavaScript, Python, Go, Ruby, Java, .NET, iOS, Android, and 90+ more
  • Self-hosted — free, unlimited events

Quick Start 

npm install @sentry/node
Enter fullscreen mode Exit fullscreen mode 
import * as Sentry from "@sentry/node";

Sentry.init({
  dsn: "https://your-key@sentry.io/project",
  tracesSampleRate: 0.1,
});

// Errors are captured automatically
// Or capture manually:
try {
  riskyOperation();
} catch (e) {
  Sentry.captureException(e);
}
Enter fullscreen mode Exit fullscreen mode

Why Every Production App Needs It

Console.log debugging doesn't work in production:

  • Real stack traces — not "undefined is not a function"
  • User context — know WHO was affected
  • Release correlation — know WHICH deploy broke it
  • Breadcrumbs — know WHAT happened before the crash

A SaaS app had a bug reported by 3 users — but Sentry showed it was actually affecting 450 users who silently churned. The breadcrumbs revealed a race condition in the checkout flow that only happened on slow 3G connections.
