# How to Monitor Replit Uptime

> Replit is a browser-based development and hosting platform where you can build and deploy web apps, APIs, bots, and AI agents, with Deployments for production hosting and Agent for AI-assisted building.

## Why Monitor Replit?

Replit makes deploying as easy as clicking a button, which means a lot of real, user-facing apps now run there — Discord bots, AI agents, internal tools, and APIs. But a Replit Deployment can still go down: a crash loop after a bad push, an out-of-memory restart, a hit usage limit, or a dependency that fails to install on redeploy. Replit doesn't tell you when your specific deployment stops answering. If people or other systems depend on it, an external monitor is what catches the outage before they do.

## What to Monitor

- `your-app.replit.app` — Your Deployment's URL — catches crash loops, OOM restarts, and failed redeploys
- `your-app.replit.app/health` — A health endpoint that confirms the app and its dependencies are actually responding
- `yourcustomdomain.com` — Your linked custom domain, if used — catches SSL and domain-linking failures

## What You Should Actually Do

1. Monitor your Deployment URL (your-app.replit.app) for a real 200 response so crash loops and failed redeploys are caught immediately
2. Expose and monitor a /health endpoint that checks your app's dependencies, not just that the process is alive
3. After every deploy, rely on monitoring to confirm the new version is actually serving — a successful build is not a working app
4. Monitor any linked custom domain separately to catch SSL and domain-linking issues
5. Track response times to spot memory pressure or approaching usage limits before they cause a restart

## Replit's Official Status Page

Replit publishes real-time status at https://status.replit.com. Your own monitor complements it by catching connection-level issues, often before the status page updates.

## Takeaway

Replit removed the friction from deploying, but it didn't remove the ways a deployment can fail — crash loops, out-of-memory restarts, hit limits, and broken redeploys all happen without a peep. For any Replit app that real people or systems depend on, an external monitor checking for a genuine response is what turns silent downtime into a 60-second alert.

## Frequently Asked Questions

### Does Replit notify me when my deployment goes down?

Not for your specific app. Replit's status page covers platform-wide incidents, but it won't tell you when your individual Deployment is crash-looping, restarting, or returning errors. That requires an external monitor pointed at your URL.

### Why did my Replit deployment stop responding?

Common causes include a crash loop after a bad push, an out-of-memory restart, a hit usage or resource limit, or a dependency that fails to install on redeploy. Most happen silently, so monitoring is how you find out.

### Can I monitor a Replit-hosted bot or AI agent?

Yes. Have the bot or agent expose a simple HTTP health endpoint and monitor that URL. If it stops returning a healthy response, you get an instant alert — far better than learning from users that the bot went quiet.

### How is this different from status.replit.com?

status.replit.com reports incidents affecting the Replit platform overall. It says nothing about your specific deployment crashing, restarting, or hitting a limit. Only a monitor on your app's URL catches your own downtime.
