About HetrixTools
HetrixTools monitors the uptime of websites and servers from up to 12 locations and alerts you when an outage is detected. It also watches SSL certificates, domain expiration and nameserver changes, and can publish status pages.
A server agent for Linux, Windows, macOS and shared hosting collects metrics, and the blacklist monitor checks whether your IPs or domains are listed, which affects email deliverability. Alerts go to 20+ integrations, including Slack, Discord, Telegram, ntfy and PagerDuty. The free tier includes 15 uptime monitors and 32 blacklist monitors.
