Testing from real traffic, not hand-written scripts
Keploy, founded in 2021 by Neha Gupta and Shubham Jain, attacks testing from an unusual angle: instead of asking developers to write tests, it records what actually happens in your application. Using eBPF instrumentation, Keploy captures real API calls — along with their database queries and downstream dependencies — and converts them into deterministic regression tests and auto-generated mocks that replay in CI with zero code changes.
Open source and AI-powered
The core platform is Apache 2.0 licensed with 17,000+ GitHub stars and over 1,000 contributors, making it one of the most popular open-source testing projects. It works across Go, Java, Python, Node.js, Rust, PHP, and Ruby. On top of the open core, Keploy layers AI agents for API testing, integration testing, and unit test generation, plus a VS Code extension with more than a million installs. The commercial tier adds AI test generation credits, contract testing, and enterprise features like SOC 2 compliance.
Funding and model
Keploy raised a $1.3M seed round in March 2022 from investors including Chiratae Ventures and Upsparks, and was part of Google for Startups Accelerator. Pricing is developer-friendly: a free playground tier, a Pro plan at $24/user/month, and the open-source core free to self-host indefinitely.
