Hey all, @sohil_kshirsagar, @jytan, @sohan_kshirsagar and I are excited to launch Tusk 2.0, a new and improved Tusk that prevents regressions by turning your app traffic into a self-maintaining test suite.
You might remember Tusk from when we were building a frontend coding agent that turned tickets into PRs. Our customers kept bumping into the same wall- the bottleneck for shipping with AI is code review.
Coding agents like Cursor, Claude Code, and Codex are generating more code than ever, but devs are spending lots of time manually verifying that vibe-coded features don't break anything downstream.
How Tusk Drift works:
Record: Our SDK instruments your Node/Python service and captures traces from user sessions. This includes the inbound request and outbound calls (HTTP, gRPC, database queries, Redis, etc.)
Replay: Tusk CLI replays those traces as tests with all external dependencies mocked from recorded data. Tests are idempotent, don't need a live DB, and run in under 50ms each.
Detect: Our Cloud platform compares current vs. recorded response bodies, classifies if a response deviation is intended or unintended, and suggests code fixes for regressions.
You get a full test suite that covers thousands of real-world edge cases in 10 lines of code. No need to manually write API tests, maintain mocks, or spin up live dependencies.
This is the frontier of code review. When you raise a PR, you can look at Tusk’s test results within minutes and see objective proof that the change works. If there are edge cases, you can easily provide Tusk’s prompt to a coding agent to cover them. We are SOC 2 Type II compliant; PII redaction can be configured.
Our CLI and SDKs are open source. Our Cloud offering is paid and used by public companies, startups, and indie developers alike. Try for free: https://app.usetusk.ai
We're offering the Product Hunt community 3 months of our paid Tusk plan for free. Use code PHLAUNCH26 at checkout.
AMA and I’ll respond as soon as possible.
