What is TestMu AI?

TestMu AI (Formerly LambdaTest) is the leading full-stack AI agentic testing cloud for end-to-end testing. AI agents plan, author, execute and analyse software quality across web, mobile and enterprise applications, running on 3,000+ browser and OS combinations and 10,000+ real devices.

More than 3M users and 18K+ enterprises across 132 countries have run over 1.5B tests on the platform. TestMu AI was named a Challenger in the 2025 Gartner Magic Quadrant for AI-Augmented Software Testing Tools and recognised in The Forrester Wave: Autonomous Testing Platforms, Q4 2025. LambdaTest rebranded to TestMu AI on 12 January 2026.

AI testing agents that write and run your tests

KaneAI is a GenAI-native testing agent. Teams plan, author and evolve end-to-end tests in natural language across web, mobile, API and database, then export them to Selenium, Playwright, Cypress or Appium with no lock-in.

Kane CLI brings the same idea to the terminal. Describe a flow in plain English and it runs in a real Chrome browser, returning pass or fail with shareable proof. It works for developers, QA teams and AI coding agents such as Claude Code, Codex CLI and Gemini CLI.

Cross-browser testing on real devices

Real Devices Cloud gives teams 10,000+ real iOS and Android devices with network throttling, geolocation testing and biometric authentication. The Agentic Test Cloud Platform extends that to 3,000+ browser and OS combinations for autonomous end-to-end testing at scale.

Test automation with Selenium, Playwright, Cypress and Appium

The Test Automation Platform runs 50+ frameworks in parallel on a cloud grid with no infrastructure to maintain. For mobile, Native App Automation Cloud runs Appium, Espresso, XCUITest and Detox suites on real devices, emulators and simulators.

Faster test execution and load testing with HyperExecute

HyperExecute is an AI-native orchestration cloud that runs tests up to 70% faster using auto-split and matrix modes, job prioritisation, FailFast and auto-healing for broken selectors. It also powers protocol-level load testing with JMeter and Gatling from managed cloud generators.

Visual testing and accessibility testing

SmartUI catches layout shifts, CSS regressions and missing elements, and its Visual AI engine cuts false positives by up to 95%. Accessibility Testing checks websites, Android and iOS apps and PDFs against WCAG A, AA and AAA, ADA and Section 508, with a Chrome DevTools extension for on-demand scans.

Testing AI agents, chatbots and voice bots

Agent Testing uses AI agents to test AI agents. It auto-generates 60 to 100+ scenarios, scores responses on hallucination, bias, context awareness and tone, tracks 30+ call metrics for phone agents, and returns a clear production-readiness verdict.

Browser infrastructure and MCP server for AI agents

Browser Cloud is scalable browser infrastructure for AI agents, offering real Chrome at scale with stealth mode, session persistence and geo proxies, and works with Playwright, Puppeteer and Selenium. The TestMu AI MCP Server connects assistants like Claude, Cursor and GitHub Copilot to test data, so failures can be triaged from the IDE.

Test management and test intelligence

Test Management turns Jira tickets, PRDs and Figma flows into structured test cases, with two-way Jira and Azure DevOps sync and manual plus automated runs in one workspace. Test Insights adds flaky test detection, failure clustering, AI root cause analysis and error forecasting.

Integrations, security and compliance

TestMu AI integrates with 120+ tools across project management, CI/CD, test frameworks and team communication, including Jira, GitHub, Jenkins, Azure DevOps and Slack. The platform is SOC 2 Type II compliant, certified for ISO 27001, ISO 27017 and ISO 27701, and follows GDPR, CCPA and HIPAA standards.
