About Web
Tusk is an AI-powered testing platform that acts as a verification layer for coding agents, automatically generating unit and API tests based on production traffic and business context. It helps prevent bugs and quality issues by catching regressions in PRs before merge, with a claimed 43% regression detection rate. Tusk features autonomous test generation that self-iterates on errors, self-healing test suites that adapt to code changes, and a CLI for easy integration into local or CI workflows. It also includes CoverBot for backfilling unit tests and supports observability monitoring.
