Monitor the experience, not only the server.
HTTP status matters, but so do broken links, JavaScript errors, failed requests, mobile issues, SSL, DNS and the buttons customers actually depend on.
A website can be online and still be broken.
Most uptime tools answer one question: did the server respond? We built Did Anything Break? around the question that actually matters to a website owner: does the website still work?
Explain what changed.
An alert should give you context. We keep a timeline, diagnostic data and recovery state so you can understand the incident instead of opening five tools.
Keep the product understandable.
Monitoring software does not need to feel like an enterprise control panel. The goal is a product a small team can open, understand and trust immediately.
