What is HostTracker
HostTracker is a website, server and API monitoring service. It runs uptime, performance, blacklist, certificate and other checks against the targets you configure - from 300+ checkpoints around the world plus HostTracker’s own internal network - and notifies you the moment something changes.
What you can monitor
Section titled “What you can monitor”HostTracker offers 14 monitor types (plus site crawl, in limited rollout), grouped by what they answer:
- Availability - Website/HTTPS, Ping and Port checks watch whether a target responds at all. DNS query, traceroute and whois are available as free instant-check tools, not recurring monitor types.
- Functionality - API monitors validate REST/JSON endpoints against status, headers and body rules (AssertRuleLang); Transaction monitors replay a multi-step browser flow (login, add to cart, checkout); Web content check crawls a page in a real browser and asserts on rendered text/keywords.
- Performance - Page speed (Waterfall) records a full-page load waterfall (DNS, connect, TLS, TTFB, content) from a real browser.
- Infrastructure - Database (SQL query probes), SNMP and Server counters (CPU/RAM/disk/performance counters) watch what’s running behind your public endpoints.
- Security & validity - SSL/TLS certificate expiry, Domain expiry, DNS blacklist (DNSBL) and Google Web Risk checks watch for problems that don’t show up as a simple outage.
- Site crawl - a scheduled, multi-page crawl that tracks broken links, indexability signals (robots, canonical, meta robots) and an overall site-health score across a site; currently rolling out and not on every plan.
HostTracker does not offer DNS record monitoring, email deliverability/SPF-DKIM-DMARC monitoring, cron/heartbeat monitoring, real-user monitoring (RUM) or APM, and it does not hold a SOC 2 certification.
How it fits together
Section titled “How it fits together”You create monitors, decide where they check from, add contacts and alerts, and optionally publish a status page. Everything is also available over the REST API and MCP server, and every account starts on a 30-day free trial with no card required.
