We had an old Node.js service, no tests, nobody on the team wrote it. Tried writing tests manually for two weeks and gave up. Too many moving parts to mock by hand. Keploy attached to it with no code changes; we ran real traffic through for a couple of days, and came out with over 130 tests. Actually reflecting how the service behaves, not how we guessed it did.

If real traffic never hits a code path, that path won't be in your tests. Makes sense, but we didn't realize we needed to deliberately trigger edge cases during recording. Would've saved us a second session. Review collected by and hosted on G2.com.

One of the things I appreciate most about Keploy is how it prioritizes the developer experience. Instead of relying on manual test creation, it captures actual API interactions to generate meaningful test cases automatically, making the testing process far more efficient and seamless. I’m also drawn to its collaborative open-source community and its strong focus on engineering excellence. Review collected by and hosted on G2.com.

What I like best about Keploy is its strong developer-first approach. It focuses on solving a real problem by making testing simple and less time-consuming for developers.

The vision of helping teams achieve high code coverage with minimal effort is exciting to me. I also appreciate the open-source culture and the fast-paced environment, which creates a great space to learn and contribute meaningfully Review collected by and hosted on G2.com.

Honestly, there isn’t anything I dislike about Keploy so far.

What stands out to me is the clarity of vision, the developer-first approach, and the strong focus on solving real problems in testing. The culture feels supportive and growth-oriented, which makes it a great place to learn, contribute, and build meaningful impact. Review collected by and hosted on G2.com.

Keploy makes achieving high code coverage faster, claiming to reach 90% coverage in just two minutes. Its most helpful feature is the ability to automatically record real API calls and transform them into test cases and mocks using eBPF technology, which effectively acts as a "time machine" for tests.

Nothing, it is all good. It's a great tool, which you can use to make testing faster, and more optimal. Review collected by and hosted on G2.com.

What makes keploy awesome is that it automatically records your real app traffic to create test cases, saving you tons of time. Plus, it lets you test your code without needing to manually set up or mock databases and third-party APIs Review collected by and hosted on G2.com.

Nothing in particular. I don’t have anything to dislike about Keploy. Review collected by and hosted on G2.com.

I use Keploy primarily for automated API testing and test generation. It eliminates the time-consuming effort of writing manual test cases, bringing reliability and speed to the entire development lifecycle. I really like its ability to capture real production-like API traffic and convert it into test cases. The automatic test case generation, API regression testing, and its ability to replay real traffic with high accuracy are quite valuable to me. The initial setup was fairly easy and straightforward.

I think Keploy could be improved by adding clearer best practices and examples for large, distributed systems to further enhance its usability. Review collected by and hosted on G2.com.

I use Keploy for testing my app infrastructure and appreciate that it provides a sandbox for testing my app APIs. I find its kernel network intercept feature very interesting. It's really easy to open Docker and run Keploy on my macOS, which I find very useful. Review collected by and hosted on G2.com.

Not sure Review collected by and hosted on G2.com.

What I appreciate most about Keploy is how seamlessly it converts real API traffic into valuable test cases and mocks, which saves a significant amount of time that would otherwise be spent on manual testing. It integrates well with existing workflows, enhances test coverage without requiring additional effort, and allows developers to concentrate on building new features rather than writing repetitive tests. In summary, it streamlines API and integration testing, making the process faster, easier, and much less tedious. Review collected by and hosted on G2.com.

Many users feel that Keploy's onboarding process and documentation could be enhanced, as newcomers often face challenges due to a lack of clear tutorials or more in-depth examples. The user interface may also appear somewhat technical for those with less testing experience. Additionally, some reviewers point out that advanced configuration and custom setups can be difficult to master, presenting a noticeable learning curve. There have also been mentions of limited support for specific environments, such as running without Docker on macOS, and occasional issues with having to regenerate fragile stubs.
