R5. Uptime monitoring

What this page helps you do​

Add a basic way to notice downtime quickly.

Why it matters​

You cannot fix downtime fast if you only learn about it from angry messages.

You should already have​

  • a deployed app

Skip this page if​

  • the app is not online yet

What to do​

  • choose a simple uptime check
  • monitor the main public route or health endpoint
  • send alerts somewhere you will actually see

Start with one public check on the main app URL.

Common mistakes​

  • checking the wrong URL
  • setting up alerts in a place nobody watches
  • thinking “it rarely goes down” means you do not need monitoring

Next step​

Go to R6. Error tracking.

Advanced notes​

TODO for contributors: add a list of beginner-friendly uptime tools with plain-language tradeoffs.
