About IsDown.app and SourceForge

In their own words, as submitted to SaaSHub.

IsDown was built out of frustration at 4 AM. Nuno Tomas, founder and on-call engineer, spent 30 minutes debugging an alert before realising the cloud provider had an outage posted on their status page, but nobody was watching it. That night, he decided there had to be a better way. Today, IsDown...

Questions & Answers

As answered by people managing IsDown.app and SourceForge.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

IsDown.app's answer

Three reasons:

  1. Coverage: 6,000+ services monitored. If your vendor has a status page, IsDown monitors it.
  2. Speed and context: Alerts go out within seconds of an incident, with full context including affected components, official vendor description, and real-time updates. Not just a notification that something is wrong.
  3. IsDown does not replace your existing tools, it completes them. UptimeRobot and Pingdom tell you your own services are down. IsDown tells you which of your third-party vendors caused it, and exactly what is happening on their end. Setup takes 5 minutes. No engineering required.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Who are some of the biggest customers of your product?

IsDown.app's answer

IsDown is used by IT, DevOps, and engineering teams across SaaS companies, MSPs, DevOps agencies, schools, and enterprise IT departments.

Which are the primary technologies used for building your product?

IsDown.app's answer

IsDown is a web-based SaaS application. The core product runs on modern cloud infrastructure with multi-region monitoring across US, EU, and Asia to ensure reliable status checks and fast alert delivery worldwide. IsDown integrates directly with Slack, PagerDuty, Datadog, Microsoft Teams, Incident.io, FireHydrant, Grafana, Rootly, Zendesk, and more, connecting alerts to wherever your team already works. For teams using AI assistants, IsDown offers an MCP (Model Context Protocol) Server that allows querying IsDown data directly from AI tools like Claude or ChatGPT.
