What it watches
https://api.yourapp.com
Any public URL. Checks status codes, follows redirects, and measures response latency. If it answers 2xx, it's up.
db.internal:5432
Verify any TCP service — databases, SSH, Redis, internal APIs, custom ports. Protocol-agnostic. If the port responds, it's up.
play.yourserver.gg
Speaks the Minecraft handshake for Java and Bedrock. Detects whether a server is actually running — not just whether a port is open.
curl uptimeduty.com/h/abc
Cron and scheduled jobs ping us when they finish. If the ping doesn't arrive on time, you hear about it.
How it works
URL, TCP port, Minecraft server, or heartbeat. Takes about 10 seconds.
Protocol-aware checks every minute, from our servers. Nothing to install or maintain.
Email, Slack, Discord, or webhook — the moment it goes down, and again when it recovers.
Public status pages
It flips red the instant a monitor goes down. No manual toggling during incidents — because nobody wants to log into a dashboard at 3am to update a status page.

Why is this free?
We built UptimeDuty to monitor our client apps at SeventhSky.id. The servers are running either way.
Yes, we'll charge someday. But right now we care more about building the right thing than building a business. Early adopters shape what this becomes — and they keep the free tier, forever. No fine print.
Why not Uptime Kuma?
But: a VPS to maintain, OS updates, Docker config, and — the killer — it goes down when your server goes down.
UptimeDuty is $0 and takes 30 seconds to set up. Your call.
