Comment
@TestMuAI Validate this PRon your pull request. -
KaneAI will automatically trigger AI-native validation and post results on the PR.
By default, KaneAI validates against the pull request's preview deployment URL. You can now point validation at a specific URL, or reach a locally or privately hosted app through TestMu AI Tunnel, by passing options directly in the trigger comment:
# Validate against a specific URL
@KaneAI Validate this PR --url <test_url>
# Validate a locally or privately hosted app through TestMu AI Tunnel
@KaneAI Validate this PR --tunnel my-tunnel-name
# Combine both — run against a local URL exposed via a tunnel
@KaneAI Validate this PR --url http://localhost:5173 --tunnel <your-tunnel-name>
Refer to the GitHub App Integration guide for the complete list of supported trigger options.
Contributions are welcome. Open an issue to discuss your idea before submitting a pull request. When reporting bugs, include your Node.js version, OS, and npm version.

On January 12, 2026, LambdaTest evolved to TestMu AI, the world's first fully autonomous Agentic AI Quality Engineering Platform.
Same team. Same infrastructure. Same customer accounts. All existing LambdaTest logins, scripts, capabilities, and integrations continue to work without change.
ð Find the new home for LambdaTest.
In 2017, we launched LambdaTest with a simple mission: make testing fast, reliable, and accessible. As LambdaTest grew, we expanded into Test Intelligence, Visual Regression Testing, Accessibility Testing, API Testing, and Performance Testing, covering the full depth of the testing lifecycle.
As software development entered the AI era, testing had to evolve, too. We rebuilt the architecture to be AI-native from the ground up, with autonomous agents that plan, author, execute, analyze, and optimize tests while keeping humans in the loop. The platform integrates with your repos, CI, IDEs, and terminals, continuously learning from every code change and development signal.
That evolution earned a new name: TestMu AI, built for an AI-first future of quality engineering. TestMu is not a new name for us. It is the name of our annual community conference, which has brought together 100,000+ quality engineers to discuss how AI would reshape testing, long before that became an industry norm.
What started as a high-performance cloud testing platform has transformed into an AI-native, multi-agent system powering a connected, end-to-end quality layer. That evolution defined a new identity: LambdaTest evolved into TestMu AI, built for an AI-first future of quality engineering.
