Comparison

UptimeSignal vs httpstat.us

httpstat.us is a tiny service that returns any HTTP status you ask for. Useful for testing error handling. UptimeSignal does the same — and then monitors the endpoints you actually care about in production.

What httpstat.us is great for

httpstat.us solves one problem well: you need a URL that returns a specific HTTP status so you can test how your client handles it. It's a fixture, not a service you monitor.

Simple URLs — httpstat.us/418 returns 418, every time
Delays — httpstat.us/200?sleep=5000 sleeps 5s before responding
No signup — Hit the URL and you're done

Where UptimeSignal fits

Same test endpoints, hosted on a real CDN

We host the same kind of status-code fixtures at api.uptimesignal.io/test/200, /test/404, /test/500, and more. Running on Cloudflare Workers, so the latency is consistently low and they're never "down for maintenance."

Monitor what you actually ship

httpstat.us is for testing your code. UptimeSignal is for watching your production APIs. Add your real health endpoints, get pinged every minute (Pro) or five (free), and receive an email the moment something breaks.

Free tier you can actually use

25 monitors free, commercial use allowed, no credit card required. Once you've tested your retry logic against our test endpoints, point a real monitor at your prod API and forget about it.

Status pages from the same dashboard

Once you're monitoring your APIs, publishing a status page is one click. Free, unlimited, with a custom domain on Pro.

When to use httpstat.us

You just need a URL that returns a specific status code, fast
You're writing unit/integration tests for HTTP client behavior
You need controllable response delays for timeout testing

When to use UptimeSignal

You want test endpoints and production monitoring in one place
You need to be alerted when your API actually breaks, not just simulate breakage
You want a status page customers can subscribe to
You're tired of bookmarking a third-party test URL — host them on a tool you're already logged into
