Assertible has been a game-changer for our API testing strategy. The ease of setting up assertions and the detailed reports have significantly reduced our debugging time. The integration with our CI/CD pipeline is seamless, allowing us to catch issues early in the development cycle. Highly recommended for teams serious about API quality.

Assertible is decent for basic API monitoring, but I've found some limitations when dealing with more complex scenarios. The documentation could be improved, and I encountered a few instances where the assertion logic wasn't as intuitive as I'd hoped. However, the uptime monitoring is reliable, and the price point is attractive. Needs some work but has potential.

I've been using Assertible for several months now to automate API testing for our microservices architecture. The integration with GitHub is fantastic, and the ability to run tests on every commit has significantly improved our code quality. The UI is intuitive, although I occasionally find myself wishing for more advanced customization options in the assertion setup. Overall, a solid tool for API testing.
