Sentry Has a Free Error Tracking Platform — Know About Bugs Before Your Users Report Them

#devops #webdev #monitoring #opensource

A production app crashed at 2 AM. Nobody knew until customers complained on Monday. The error? A null pointer in a rarely-used code path.

Sentry catches every error, crash, and performance issue in real-time. Stack traces, user context, release tracking - know what broke and why.

What Sentry Offers for Free (Developer Plan)

  • 5,000 Errors/Month - Track errors across all projects
  • 10,000 Performance Events - Monitor transaction performance
  • 1 User - Perfect for solo developers
  • All Platforms - JavaScript, Python, Go, Ruby, Java, PHP, .NET, mobile
  • Stack Traces - Full stack traces with source maps
  • Release Tracking - Associate errors with deployments
  • Alerts - Email, Slack, PagerDuty notifications
  • Session Replay - See what user did before crash

Quick Start 

npm install @sentry/node
Enter fullscreen mode Exit fullscreen mode 
import * as Sentry from '@sentry/node'
Sentry.init({ dsn: 'https://your-dsn@sentry.io/123' })
// That's it. Errors are automatically captured.
