Uptime checks
Check whether a monitored website responds successfully and identify availability interruptions.
Know when your website is up.
PulseWatch is a lightweight website monitoring project focused on availability checks, response-time visibility, and a readable history of service incidents.
Check a website instantly
Enter a public HTTPS address to verify its DNS and test its HTTPS connection. Results appear here without adding it to the monitor list.
Quick checks are one-time browser tests, not continuous monitoring. Some sites hide HTTP status codes from browsers through CORS; PulseWatch will show that limitation rather than guess.
Clear visibility into website health
The project is being designed around the essential signals that help developers understand whether a website is reachable and how it is responding.
Response-time tracking
Record request duration to help reveal slow responses and performance changes over time.
Incident history
Keep a chronological record of detected outages and recoveries for easier troubleshooting.
Built for a lightweight workflow
PulseWatch checks a curated list of public websites on a five-minute schedule using GitHub Actions. Community members can request additional sites for review through the Add a website page.
Monitoring is best-effort and is not an uptime SLA. Community-submitted websites are reviewed before they are added. Check history begins when monitoring starts; past uptime is not inferred.
