What is TestMu AI?

TestMu AI is an AI-native, agentic testing cloud for end-to-end software quality engineering across web, mobile, and AI applications. It combines test authoring in natural language, a browser and real-device cloud to execute on, orchestration to run suites in parallel, and AI analysis of results, allowing teams to plan, write, run and debug tests without assembling separate tools.

Is LambdaTest still available?

Yes. LambdaTest is now TestMu AI. The company rebranded on January 12, 2026 to reflect its evolution into an AI-native testing platform. All LambdaTest products, features, integrations, and infrastructure remain fully available under the new TestMu AI brand at testmuai.com. Existing customers experienced no service interruption.

What products are included in the TestMu AI platform?

The platform includes KaneAI for test authoring in natural language, cross-browser testing across 3,000+ browser and OS combinations, real device cloud with 10,000+ devices, HyperExecute for test orchestration, SmartUI for visual regression testing, accessibility testing, Test Manager for test case management, and agent testing for chatbots and voice assistants. All products share one account and execution cloud.

What does it mean that TestMu AI is agentic rather than just AI-powered?

Agentic means the system carries a task across steps autonomously. It can take a requirement, ticket, or plain-English description, plan what needs covering, author tests, run them on the cloud, and diagnose and repair what broke without being re-prompted at each stage. This is particularly valuable in maintenance as suites can repair their own selectors and re-plan after UI changes.

Is TestMu AI free to try?

Yes. Signing up requires no credit card and the free tier has no time limit. It includes limited live testing sessions that renew monthly and SmartUI's free tier with 2,000 visual regression screenshots and 1-month build history. KaneAI has a 14-day free trial, after which plans start at $17 per agent per month billed annually.
