About X
Tusk is an open-source tool that automatically generates unit and integration tests from production traffic. It requires only 10 lines of code to integrate, leveraging AI to catch bugs that humans and AI agents might miss. Backed by Y Combinator (YC W24), it uses a persistent environment (E2B) to generate tests based on your codebase, covering edge cases and preventing regressions.
Key Features
Generates unit and integration tests from production traffic
Requires only 10 lines of code for integration
AI-enabled test generation to catch bugs missed by humans and AI agents
Uses E2B persistent environment for test execution
Covers edge cases and prevents regressions
Based on real production traffic to improve test reliability
