As answered by people managing IsDown.app and SecurityBot.dev.
IsDown.app's answer
IsDown monitors official vendor status pages directly, not just crowdsourced reports. This means alerts include real incident context: what broke, which components are affected, and real-time resolution status. Not just "something is down." Combined with crowdsourced early detection signals, IsDown can catch outages before vendors acknowledge them. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported. Every team monitoring cloud services already has uptime tools that ping their own URLs. IsDown tells you what is happening with the third-party services your stack depends on, before your users feel it.
IsDown.app's answer
Three reasons:
IsDown.app's answer
IsDown is built for IT managers, DevOps engineers, and SREs at companies that rely on multiple cloud and SaaS services, which means any team running on cloud infrastructure. The core audiences are DevOps and SRE teams who are on-call and need to know instantly when a third-party service causes an incident; IT managers responsible for vendor oversight and SLA compliance; MSPs and agencies managing cloud infrastructure for multiple clients; and engineering teams who want to stop wasting time debugging problems that turn out to be vendor outages. Customers span SaaS companies, schools, DevOps agencies, and enterprise IT teams across industries.
SecurityBot.dev's answer:
SecurityBot is used by a mix of established tech companies and indie entrepreneurs.
IsDown.app's answer
IsDown was built out of frustration at 4 AM. Nuno Tomas, the founder, was on-call when a PagerDuty alert woke him up. After 30 minutes of debugging, he realised the problem was not his code. It was the cloud provider. They had posted an outage on their status page, but nobody on the team was watching it. That night, he decided there had to be a better way. He built the first version of IsDown so his team would never be the last to know about a vendor outage. Founded in 2020, IsDown has since grown to monitor 6,000+ services, perform over 1 billion status checks, detect 520,000+ outages, and send 5.2 million+ notifications. The same problem Nuno solved for his team that night is now solved for IT, DevOps, and engineering teams around the world.

He originally built SecurityBot.dev to monitor his own products, and it worked so well that he subsequently released it for wider use.
IsDown.app's answer
