Great Tool for Automated API Testing

Pros: What I like most about Keploy is how it simplifies backend testing for developers. Its automated test generation saves time and reduces the manual effort usually required for maintaining test cases. I also admire the company’s open-source mindset and clear vision toward improving developer productivity. The collaborative and fast-moving environment makes it a great platform for learning, contributing, and building impactful solutions
Cons: Honestly, there isn’t much to dislike about Keploy so far. The only improvement I’d suggest is increasing the free plan limit of 30 test suites per month, as active developers and small teams may need more flexibility for continuous testing
