Tusk 2.0 – Test code changes with production traffic

Summary: Tusk 2.0 is an open-source platform that converts real user traffic into automated unit and API tests, enabling developers to validate code changes against actual usage patterns and prevent regressions efficiently.

What it does

Tusk instruments Node and Python services to record user session traces, including inbound requests and outbound calls. Its CLI replays these traces as idempotent tests with mocked dependencies, while the Cloud platform detects response deviations and suggests fixes.

Who it's for

It is designed for developers and teams seeking automated regression testing based on real-world app traffic to streamline code review and validation.

Why it matters

Tusk addresses the bottleneck of manual verification in code review by providing a self-maintaining test suite that covers thousands of edge cases without requiring manual test writing or live dependencies.
