Simulate real world traffic to
detect regressions

Our SDK records API calls made to and from your Node.js and Python service in production to cover thousands of edge cases

How it works

Why Tusk Drift?

Run fast, idempotent API tests without
requiring a live database or cache

Resolve regressions before they reach prod

Replay traces recorded from real traffic as tests to find unintended deviations in your PRs or locally via Tusk CLI. No need to write or maintain API tests.
