Automatically generate API tests and mocks using real production traffic.
Captures live production API traffic using lightweight Kubernetes sidecars or reverse proxies. Automatically creates realistic load tests, stress tests, and regression suites from traffic. Generates intelligent service mocks and virtual environments to isolate microservices during testing. Attaches automated performance and payload validation reports directly to Git pull requests.
Uses actual user traffic instead of synthetic or guessed test scripts for true-to-life coverage. Decouples microservice team dependencies by automatically mocking downstream APIs. Accelerates CI/CD delivery pipelines by shifting realistic performance testing left. Reduces staging infrastructure costs by eliminating dedicated, static staging environments.

Speedscale is a developer tool and API testing platform built specifically for Kubernetes environments. It captures real-world production API traffic and automatically converts it into reusable test scenarios and mock dependencies. By simulating production workloads and third-party API behaviors in lower development environments, Speedscale prevents regressions and performance bottlenecks before code reaches production. It integrates directly into CI/CD pipelines to replace fragile manual test scripting.
Speedscale was founded in 2020 in Atlanta, Georgia, by Ken Ahrens, Matthew LeRay, and Nate Lee. Drawing from decades of combined experience in observability and APM at New Relic, Observe, and CA Technologies, the founders realized that testing distributed Kubernetes microservices was overly manual and prone to unexpected production failures. They created Speedscale to let production traffic automatically build environment-accurate test suites.
