AI-Native Test Automation Platform
Author tests with AI agents, or run your existing Selenium, Playwright, Puppeteer and Cypress tests on a scalable test automation platform across 3000+ real browsers, devices and OSes, without maintaining local grids.
Automate Browser Flows from your
Terminal with Kane CLI
Trusted by 2M+ users globally at
"We have tripled our tests and are now executing tests in less than 2 hours with 78% Faster Test Execution"
"We figured out a more efficient way to monitor system health and resolve failures earlier in lower environments."
"TestMu AI has significantly boosted our testing speed, is easy to implement, and provides exceptional support."
"With 70% faster test execution, TestMu AI helped us achieve faster time-to-market and enhanced CX."
Why Choose Test Automation Platform by TestMu AI (Formerly LambdaTest)
Author tests with AI, run them in parallel across Playwright and every framework, and ship faster with HyperExecute and CI/CD integration.
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.
Faster Release Cycles
Cut Build Time with Parallel Testing
Run automated tests concurrently across browser and OS combinations on TestMu AI (formerly LambdaTest) and reduce your overall test execution time.
Get Started For Free- Scale concurrent test sessions on demand with no grid provisioning or upfront infrastructure setup.
- Run your full regression suite on every pull request without blocking merges or delaying a release.
- Offload Selenium Grid maintenance and infrastructure overhead to a fully managed, autoscaling cloud.
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.
The execution time we got using HyperExecute, that's the major differentiator.

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.
Seamless Integration
Integrate Into Your CI/CD Pipeline in Minutes
Connect TestMu AI (formerly LambdaTest) to your CI/CD pipeline and run automated tests on every commit without reworking your workflow.
Get Started For Free- Install pre-built plugins for Jenkins, GitHub Actions, and GitLab with automated result parsing.
- Trigger test runs on every commit and gate pull request merges on pass/fail status.
- View execution logs, build summaries, and failure reports directly inside your CI/CD dashboard.

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

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.
