Assertible vs HostTracker

Assertible tests and monitors APIs, websites, and other HTTP services for uptime, availability, and correct behavior. Users create HTTP assertions, inspect request details, and review assertion results. The service can run smoke tests automatically after deployments to staging or production environments. API tests can be imported and synchronized with OpenAPI or Swagger specifications and Postman collections. Integrations listed in its documentation include GitHub deployments and status checks, Slack, PagerDuty, and Zapier. Monitoring schedules range from once per minute to once per day, with shorter intervals available on paid plans. Plans limit services, tests per service, retained results, team members, and schedule frequency rather than monthly request counts. The Personal plan costs nothing and includes two web services, 10 tests per service, 1,000 results, one to two members, and Standard monitoring with two monitors. Paid plans are Standard at $25 a month, Startup at $50 a month, and Business at $100 a month; each includes a one-month trial.

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.
