Speedscale Platform is a Kubernetes traffic replay and API testing tool for cloud-native engineering teams.
Speedscale Platform captures production API traffic via eBPF or sidecar proxy and replays it against code changes before deployment, enabling engineering teams to detect performance regressions without writing test scripts.
Core capabilities include load testing at scale, service virtualization, and API observability for Kubernetes workloads. Enterprise customers including Sephora, Vistaprint, and Zenni Optical rely on the platform to validate microservice behavior under real traffic conditions.
