HostTracker
Website and uptime monitoring from 300+ locations with phone call, SMS and Slack alerts.
HostTracker is an external website monitoring service that checks websites, servers and APIs from outside your own network around the clock. Failures are re-checked from other locations before an alert is raised, helping distinguish a real outage from a single bad route. Checks run from over 300 checkpoints worldwide on around 460 distributed agent machines, and the service has been operating since 2004.
It offers 14 monitor types, including HTTPS uptime, ping, TCP port, API, browser transaction, page speed, web content, database query, SNMP, DNS blacklist, domain expiry, SSL certificate expiry and Google Web Risk. Alerts can be sent through 15 channels such as email, SMS, voice call, webhook, Slack, Teams, PagerDuty, Telegram and Discord. Public status pages, scheduled reports, a REST API with SDKs, a CLI, a Terraform provider and an MCP server for AI assistants are also available.
HostTracker is aimed at people managing multiple sites, including web agencies, hosting resellers and webmasters. It is packaged with a free 30-day trial requiring no credit card, a limited free plan, and paid editions that differ by monitor count and check frequency, with plans starting from a single monitor.
