Open Source Testing AI Agent Developer Tools API Automation QA

Overview

Keploy is an open-source, AI-powered testing platform that captures real API traffic with eBPF and replays it in CI as deterministic regression tests, auto-generated mocks, and production-like sandboxes with zero code changes. It supports any language (Go, Java, Python, Node.js, Rust, PHP, Ruby) and any framework. Advanced features are available through the managed cloud. Keploy offers a free tier where developers can try the platform with 30 test suites/month and 5 AI credits. The platform is also available in a Pro tier ($24 per user/month) and an Enterprise tier with custom support and SOC2/SLAs. The OSS core remains free to self-host indefinitely. The platform allows developers to record regression tests from real API traffic and replay them into CI as isolated sandboxes. This process takes milliseconds, making it much faster than traditional testing methods. Keploy's features include the ability to support any language and framework, generate auto-mocks, and maintain production-like sandboxes with zero code changes.

Does the job

Pretty happy overall. The API just works and it is genuinely easy to set up. The docs could be deeper can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Compared a few options

Evaluated this against two competitors. Where it wins: the onboarding and support is responsive. Where it lags: the docs could be deeper. On balance the feature set — especially the automation — justifies the 5 stars for our use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the API, and support is responsive caught me off guard. The mobile experience lags is why this isn't a perfect score, still, I'd recommend giving it a real trial.
