Free uptime checks from a global monitoring network.
NOT REALLY
why this verdict
Keep it — OpenAI has not replaced it
OpenAI's version overlaps, but does not finish the dev tools job, so this one is still worth keeping open.
- A named launch, not a vibe named, unlinked
- Nothing a model produces can watch your site from outside it. OpenAI, January 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 1 of 2 listed replacements have a usable free tier: Better Stack.
- What the call is worth nothing to cancel
- No paid entry tier tracked, so there is no subscription to cancel.

The backstory
UptimeRobot is the first monitor almost every indie project gets, because the free tier covers fifty checks and takes a minute to set up. External vantage points and an SMS at 3am are physical infrastructure — the definition of something AI cannot substitute for.
