WEBSITE & API MONITORING

Know before your customers do

We check your site around the clock and email you the moment it stops answering — with the status code, the response time and how long it has been down.

About us

Monitor what matters

Website Onlines exists to answer one question quickly and honestly: is it up? Every alert names what failed, when it started and what the response actually was, so the first minute is spent fixing rather than diagnosing.

A check has to fail twice in a row before anyone is emailed, so a single blip stays quiet. When it recovers, you get one message with the total downtime — and nothing else.
