Your users won't report bugs — they'll just leave. Error monitoring catches problems so you can fix them before anyone notices.
Bugs happen, even in production. Without monitoring, you won't know something is broken until someone complains — and most people never complain, they just leave.
Most errors happen without anyone telling you. A broken checkout could lose you sales for days.
Error monitoring tells you the exact page, button, and line where things went wrong.
Get an email or Slack notification the moment something breaks, not days later.
See if errors are increasing after a new release so you can roll back quickly.
It's simpler than you think. Here's the basic idea:
Tell your AI tool to add an error monitoring service. It adds a small piece of tracking to your project.
When something breaks on your site, the tool automatically catches the error and sends a report.
You receive an alert (email, Slack, etc.) with details about what went wrong and where.
The report shows you exactly which page and feature broke, so you can tell your AI tool to fix it.
Pick one that fits your needs. Sentry is the most popular choice for most projects.
Error Tracking
The most popular error monitoring tool. Catches errors, shows stack traces, groups duplicates, and alerts you instantly. Generous free tier.
Best all-around choice. Start here if you're unsure.
Session Replay + Errors
Records user sessions so you can replay exactly what happened before an error. Like a DVR for your website. Great for debugging tricky issues.
Best when you need to see exactly what the user did.
Built-in Error Tracking
If you deploy on Vercel, you get basic error logging in your dashboard. Shows runtime errors, function failures, and deployment issues.
Good starting point if you're already on Vercel.
Full-Stack Monitoring
Session replay, error monitoring, and logging in one tool. Open source with a nice UI. Good alternative to LogRocket.
Uptime + Logging
Combines uptime monitoring, error logging, and incident management. Beautiful status pages. Great for knowing when your site goes down.
Just tell your AI tool which service you want, and it will handle the installation and configuration.
Add Sentry error monitoring
"Add Sentry error monitoring to my Next.js project. Set it up to capture both client-side and server-side errors. Include the Sentry configuration file and add the error boundary wrapper. Use my Sentry DSN from my environment variables."
Add LogRocket session replay
"Add LogRocket to my Next.js project for session recording and error tracking. Initialize it in my root layout and configure it to record user sessions. Make sure it identifies logged-in users by their email."
Set up basic error tracking
"Add a global error handler to my Next.js project that catches unhandled errors and logs them. Create a custom error page (error.tsx) that shows a friendly message to users when something goes wrong, and a not-found page (not-found.tsx) for 404 errors."
Make your error handling user-friendly and effective.
Create friendly error pages instead of showing scary technical messages. A nice 404 page with a link home is much better than a blank white screen.
Tell your AI tool to add error boundaries. These catch errors in one part of your page without crashing the entire site.
Configure notifications so you get alerted when new errors appear. Email is fine to start. Slack or Discord integrations are even better.
After pushing an update, check your error monitoring dashboard. New errors that appear right after a deploy are usually caused by that deploy.
Uptime monitoring checks if your website is online every few minutes. If it goes down, you get alerted immediately instead of finding out from angry users.
Uptime + Status Pages
Monitors your site every 30 seconds. Beautiful public status pages to show users your uptime. Alerts via email, Slack, SMS, and phone calls.
Simple Uptime Monitoring
Simple and reliable. Checks your site every 5 minutes on the free plan. Get alerts when your site goes down and back up. Monitors up to 50 sites for free.
Copy-paste these prompts into your AI tool to apply what you just learned.
SET UP SENTRY ERROR TRACKING
"Set up Sentry error tracking in my Next.js app. I want to catch client errors, server errors, and unhandled promise rejections."
DIAGNOSE A RECURRING ERROR
"My Sentry dashboard shows this error happening frequently: [paste error]. Help me find the root cause and fix it."
Quick start:Add Sentry for error tracking and UptimeRobot for uptime monitoring. Both are free, and together they cover the basics. Tell your AI tool to set them up and you'll be done in minutes.
