Speedscale is a Kubernetes-native traffic replay platform for API testing and regression validation.
Speedscale is a Kubernetes-native platform that captures real production API traffic via eBPF or sidecar proxy and replays it against code changes before deployment, enabling engineering teams to detect performance defects without writing test scripts.
The platform consolidates load testing, service virtualization, API observability, and the Proxymock free local-development mocking tool into a single offering, with support for cloud-hosted and bring-your-own-cloud deployment options.
Speedscale's core differentiator is traffic-based test generation that requires no scripting: engineers capture real production API requests via eBPF or sidecar proxy and replay them against new code, enabling regression detection in minutes rather than days compared to scripted load testing frameworks such as Gatling, JMeter, or K6.
The service virtualization layer generates dependency mocks directly from recorded production traffic, eliminating reliance on live third-party APIs or hand-authored stub files, which reduces flaky test failures and supports fully isolated pre-production validation in Kubernetes.
Speedscale's Kubernetes-native architecture limits applicability for organizations running monolithic or non-containerized workloads, and its traffic-replay approach requires production traffic capture infrastructure, adding setup overhead compared to scripted load testing tools that work against any HTTP endpoint.
As a small startup with a reported headcount in the low double digits, Speedscale may face evaluation challenges competing against larger testing vendors on breadth of enterprise support tiers, compliance certifications, and global support infrastructure.
