HostTracker monitors websites, servers and APIs from outside a customer's network. Its listed checks include HTTPS uptime, ping, TCP ports, APIs, browser transactions, page speed, database queries, SNMP, domain and SSL expiry, and Google Web Risk. HostTracker says checks run through over 300 worldwide checkpoints on around 460 distributed agent machines; failing checks are rechecked elsewhere before alerts. Users can set the number of confirmations required before a monitor is declared down. Alert channels include email, SMS, voice calls, webhooks, Slack, Microsoft Teams, PagerDuty, Telegram, Discord and web push. Every plan includes public status pages with incidents, maintenance windows, email subscribers and an embeddable uptime badge. Developer options include a REST API, SDKs for JavaScript, Python,.NET and Go, a command-line tool, a Terraform provider and an MCP server. The permanent free plan monitors two sites with checks every 30 minutes. A 30-day trial includes up to 100 monitors, with fair-use limits on SMS and API access. Paid plans start at $5 a month.
