Tusk

Tusk generates and maintains automated tests for API, unit and integration testing, using live production traffic to catch regressions in pull requests. It runs through a CLI with autonomous test iteration and self-healing suites. Note that the company has announced it is sunsetting.

Tusk is an AI verification layer aimed at teams that ship code with coding agents and want a safety net before merge. Its pitch is straightforward: use production traffic and business context to generate test cases that catch real world regressions, rather than relying on synthetic examples that never touch how the product is actually used. The company reports that its generated tests surface issues in 43% of pull requests, and it frames the product as a way to keep agent written code honest without slowing engineers down. In practice the workflow runs through a CLI. A single install command sets Tusk up in the service root, and a setup command configures Drift, the component that works from real API traffic. From there Tusk adds generated tests locally or to an existing branch, runs them locally or in CI, and comments on pull requests with the suites it has produced. The system is described as fully autonomous: when a generated test fails on its own errors, it iterates without a human prompting an AI copilot back and forth. Existing suites are maintained too, with self-healing tests refreshed on every commit so they track current business logic. Coverage is the headline outcome. Tusk positions itself around reaching coverage goals, fixing functional bugs, and detecting regressions in the pull request stage, alongside enforcement of coverage and quality requirements. Published customer accounts describe large jumps: Hamming moving from roughly 2,500 to more than 7,000 tests on a core area within a month, and TeamFeePay attributing about three quarters of a recent coverage increase on a legacy codebase to Tusk. Buyers should note a significant caveat that appears on the site itself: a resources post dated June 2026 announces that Tusk is sunsetting. That makes the listing relevant mainly to teams evaluating the approach or reading the case studies rather than planning a long term rollout. Pricing is not published on the homepage, and evaluation starts through a demo request.
