Keploy

What is Keploy?

Keploy is an open-source, AI-powered testing platform that turns real application traffic into automated tests.

Using eBPF to capture API calls, database queries, and streaming events at the network layer, it records what your application actually does in development or production and replays that traffic in CI as deterministic regression tests, complete with auto-generated data mocks and production-like sandboxes, all without requiring code changes.

js, Rust, PHP, Ruby, and more. This approach lets teams generate broad test coverage and realistic mocks faster than hand-writing unit tests, and the isolated sandboxes let API, integration, and end-to-end tests run safely. 0 license with a large community of contributors.

Typical users are backend and platform engineers who want fast, low-effort regression coverage for services and APIs without maintaining heavy test scaffolding. Pros include zero-code-change setup, language agnosticism, and automatic mock generation that removes a major source of testing friction.

Cons include that eBPF-based capture can have environment and permission constraints, and AI-driven test generation features beyond the open-source core require paid credits. Pricing is freemium, with a free playground tier, a paid Pro plan, and enterprise options.

Pricing changes often, so check the official site for current plans. Keploy's core capabilities include eBPF traffic capture with zero code changes, Replays traffic as deterministic regression tests, Automatic data-mock generation, Language- and framework-agnostic and Production-like test sandboxes.

EBPF traffic capture with zero code changes is built in, Replays traffic as deterministic regression tests is built in, Automatic data-mock generation is built in, Language- and framework-agnostic is built in, so you get a rounded toolkit rather than a single trick.

Each feature is designed to take the manual effort out of the task and help you reach a usable result faster, which is what makes Keploy worth a place on your shortlist.

On the plus side, users consistently highlight No code changes needed to generate tests, Works across any language or framework and Auto-generated mocks reduce testing friction as the reasons they keep using Keploy.

It isn't perfect, though — eBPF capture has environment and permission constraints and Advanced AI test generation needs paid credits are the trade-offs people most often mention, so weigh those against your own priorities before you commit.

As with any AI tool, the output still benefits from a quick human review, but Keploy gets you most of the way there with far less effort.

Keploy runs on a freemium pricing model, so you can start for free and only pay once you outgrow the free tier — handy for testing it on a real task before spending anything.

AI-tool pricing changes often, so always check the current plans, seats and add-ons on the official site for the latest details before you buy. Who is Keploy for? It's best suited for open-source ai testing from real api traffic.

Whether you're a beginner trying this kind of AI tool for the first time or a professional who'll use it every day, it's a credible option to consider.
