Assertible vs CA App Synthetic Monitor

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.
