Our verdict on Assertible
Assertible is a web-based platform for developers, QA professionals, and teams that need to test and monitor HTTP APIs and web services. It combines response assertions, scheduled API monitoring, environment-specific testing, post-deployment checks, and uptime monitoring in one hosted workspace. Its testing scope covers status codes, JSON, headers, text, XML/HTML, response time, and links, with support for several authentication methods.
Pricing is structured around four monthly plans. Personal FREE supports 2 web services, 10 tests per service, 1,000 retained results, 1–2 members, and a standard schedule with 2 monitors. Standard costs $25 per month and adds 25 web services, 500 tests per service, 5,000 retained results, and upgraded schedule frequency, but includes 1 member. Startup costs $50 per month with the same service, test, retention, and schedule allowances as Standard and expands membership to 10 members. Business costs $100 per month and provides 50 web services, 1,000 tests per service, 10,000 retained results, 20 members, and upgraded schedule frequency. Paid plans include a one-month free trial.
Assertible fits teams that want hosted monitoring with a practical path from specifications and existing collections to scheduled checks. OpenAPI and Swagger synchronization, Postman and curl imports, setup and teardown HTTP steps, and the Deployments API support different testing workflows. GitHub, Slack, PagerDuty, and Zapier integrations extend collaboration and incident notification. Teams needing a web-based API testing service with scheduled runs and deployment checks should consider it; organizations seeking broader automated testing beyond HTTP and web-service workflows may prefer a wider platform.
