# Speedscale Documentation

> Documentation for Speedscale, a runtime validation platform for API changes. Speedscale captures real traffic and replays it against new code to catch behavioral regressions before release, including Kubernetes collection paths using eBPF-based traffic capture first and goproxy sidecars as fallback. This documentation covers Speedscale Platform, proxymock, and supporting workflows.

## Product definition

- **What it does:** records API behavior and validates new builds with replay.
- **Who it serves:** engineering, platform, DevOps, and SRE teams.
- **How it differs:** uses real traffic and runtime comparison, not only synthetic tests.

## Security operating models

- **Local recording:** proxymock supports local record/mock/replay workflows where traffic stays local unless explicitly pushed.
- **BYOC:** Speedscale can run in customer-controlled cloud boundaries for sovereignty and compliance requirements.
- **DLP:** sensitive fields can be redacted before data leaves the customer network.
