"With 70% faster test execution, TestMu AI helped us achieve faster time-to-market and enhanced CX."
Why Choose This Test Automation Platform by TestMu AI (Formerly LambdaTest)
Author tests codeless or in code, debug failures with AI, and govern the whole QA organisation from one automation testing platform.
AI Test Authoring
Author Tests in Natural Language with KaneAI
Describe a scenario in natural language and KaneAI plans, authors, and maintains the test case for you, no scripting required.
- Import Jira tickets, PRDs, images, or spreadsheets and KaneAI converts them into structured test cases.
- Edit and evolve test cases in natural language as your application changes, with zero script rewrites.
- Trigger KaneAI-authored test cases from the terminal or any CI/CD pipeline using the Kane CLI integration.
Codeless Automation
Codeless Test Automation, No SDETs
Manual QA, product, and support teams build automated tests in plain English. No code and no engineering backlog.
Get Started For Free
- Describe a test in natural language and the platform generates the executable test case.
- Low code editing keeps every generated test readable and reviewable by the whole team.
- Export to Selenium, Playwright, or Cypress at any point, so codeless never becomes lock-in.
Playwright at Scale
Run Your Existing Playwright Suite at Scale
Run your existing Playwright suite on the test automation platform at scale without changing test code, reporters, or CI configuration.
- Run Playwright test scripts in parallel across 3000+ real browser, OS, and device combinations.
- Let Auto-Healing re-resolve broken locators at runtime to keep flaky tests out of your suite.
- Execute Playwright tests on real Android and iOS devices for production-accurate test results.
Faster Test Execution
Execute Test Suites 70% Faster with AI-Native HyperExecute
HyperExecute is an AI-native orchestration platform that executes automation suites up to 70% faster than a conventional cloud grid.
- Auto-split the test suite across runners with smart orchestration so more tests run in parallel.
- Fail fast and halt the entire job the moment a critical test breaks, so no compute is wasted.
- Rerun only the failed tests while AI-driven root cause analysis pinpoints the exact failure.
Rich Test Logs
Debug Test Failures with AI Reporting
Every test session is captured in full and AI surfaces the exact failure, so your team resolves defects without reproducing them locally.
Get Started For Free- Enable custom debug options and verbose logging to capture full context on every test failure.
- Trace exactly where a request failed using network HAR logs, console logs, and session telemetry.
- Track per-session performance metrics and video logs to catch regressions before production.
Enterprise Test Automation
Enterprise Test Automation, Governed
Roll out across many teams without losing control. Role based access, single sign on, and audit trails come standard.
Get Started For Free- SSO, SCIM provisioning, and role based access keep large QA organisations governed.
- SOC 2, GDPR, and enterprise data residency controls satisfy security review up front.
- Dedicated support with SLA guarantees, plus private cloud deployment where policy requires it.

Works with all Agents:
& more...
Choose Codeless, Code, or Both
Author in plain English with KaneAI or write Selenium, Playwright, Cypress, and Puppeteer by hand. Both run on the same platform with shared reporting.
Capabilities Baked Into Every Test Session
Self-Healing Locators
When a locator changes or is renamed, the platform re-resolves it at runtime so a single DOM change no longer fails a passing test.
SmartWait for Stable Runs
Replace hardcoded sleep() calls with condition-based waits so a test pauses only until the element is actionable.
Core Web Vitals per Build
Capture Lighthouse performance metrics from each test run without adding a separate auditing tool.
Geo & Timezone Emulation
Validate localized flows across 170+ regions and timezones without proxies or physical devices.
HTTP Header Injection
Inject custom HTTP headers into any test session to exercise auth states, feature flags, and A/B variants.
Camera & Media Mocking
Inject mock video into WebRTC and camera-based flows to automate them without physical hardware.
Automate Beyond the Basics
Simulate real network conditions, test apps behind your firewall, drive the browser over CDP and WebDriver BiDi, and keep sensitive data out of your logs, on every test run.
Headless Execution
Run automated tests in headless mode to maximize execution speed in your CI/CD pipeline.
Network Throttling
Validate behavior under simulated 3G, 4G, and 5G network conditions before release.
Secure Tunnel
Automate apps behind firewalls and VPNs over an encrypted private tunnel.
Chrome DevTools Protocol (CDP)
Intercept requests, grab logs, and run performance traces on the cloud.
WebDriver BiDi
Stream live browser events to your test runner across Chrome and Firefox.
Data Masking
Keep sensitive data out of logs and recordings during remote sessions.
Supports all Major Frameworks and Languages

HyperExecute for Private Cloud
Keep every automated test run inside your private cloud, with all data behind your firewall and full control over runners and storage.
Enterprise Access & Governance
Run teams at scale with SSO, role-based access, audit trails, and policy enforcement applied across the whole organization.
CLI Integrations with Every Pipeline
Drop the HyperExecute CLI into any CI/CD pipeline to push scripts and keep end-to-end testing tied to each deployment.
LambdaTest is now TestMu AI
On January 12, 2026, LambdaTest became TestMu AI, the same trusted testing cloud, rebuilt for the AI era.
It is now a full-stack agentic AI quality engineering cloud that automates end-to-end testing across web, mobile, and AI apps. The platform is AI-native, with autonomous agents that plan, author, run, analyze, and optimize your tests.
The next era of the world's first fully Autonomous Agentic AI Quality Engineering Platform is here.
