Tusk AI

Tusk is an AI-powered testing platform designed to serve as a verification layer for coding agents. It leverages live production traffic and business context to automatically generate test cases that catch real-world regressions, reportedly spotting issues in 43% of pull requests. The platform offers a CLI for easy setup, autonomous test iteration (self-healing tests), and integrates with CI/CD pipelines to shift-left testing. It supports unit tests, API tests, and coverage backfilling via CoverBot. Tusk provides both cloud and self-hosting options, with plans ranging from free (individual developers) to team and enterprise tiers. The tool is used by engineering leaders at companies like DeepLearning.AI, Hamming, Promptfoo, and TeamFeePay. However, Tusk has announced it will sunset on June 10, 2026, limiting its long-term viability.
