Noida: TestMu AI, formerly known as LambdaTest, has announced a strategic rebrand as it transitions into the world’s first full-stack Agentic Quality Engineering platform.
With this move, TestMu AI positions itself at the forefront of autonomous software testing as AI-driven development accelerates code creation at unprecedented scale.
The rebrand marks a pivotal evolution from a cloud-based testing platform to an AI-native, agentic quality engineering ecosystem designed to address a growing industry challenge – ensuring software quality in the era of infinite, AI-generated code.
TestMu AI enables quality engineering systems that can reason, observe failures, and adapt continuously, eliminating traditional testing bottlenecks.

TestMu AI Introduces Vibe Testing for the Age of Infinite Code
As agentic AI reshapes software development, TestMu AI introduces autonomous testing agents that allow developers to “vibe test” applications at the speed of thought.
These AI agents ensure that applications built through vibe coding maintain reliability, performance, and quality before reaching end users.
The platform currently powers over 1.5 billion tests and serves more than 18,000 enterprise customers across 90+ countries, including Microsoft, OpenAI, NVIDIA, Vimeo, and Dunelm. This expansion follows the company’s reported average year-on-year growth of 110% over the past two years.
Founded in 2018 as LambdaTest, the company quickly emerged as a trusted name in cloud-based test orchestration and execution. Its high-performance test cloud addressed flakiness, enhanced developer feedback loops, and significantly accelerated release cycles for global engineering teams.
In 2022, the company initiated a deep shift toward agentic AI, embedding autonomous intelligence across its products and workflows. Today, TestMu AI supports over 2.8 million developers and testers worldwide through a unified AI-agentic platform that delivers end-to-end quality engineering at scale.

TestMu AI Platform Capabilities Powered by Agentic AI
The rearchitected TestMu AI platform is built as AI-native and deploys autonomous AI agents across the software testing lifecycle. Key capabilities include:
- Autonomous AI Agents for Testing: AI agents that plan, author, execute, and evolve tests using natural language prompts or organizational context, covering databases, APIs, UI, performance, and more.
- Agentic AI Test Cloud: A unified and scalable test execution environment supporting web, mobile, visual regression, accessibility, API, and performance testing, including custom enterprise setups.
The name TestMu AI originates from the company’s developer community. Since 2022, the TestMu Conference has served as a central forum for discussions on AI and quality engineering.
By adopting this identity, the company reinforces its community-first approach and integrates the collaborative spirit of the conference into its platform.
The company has also received industry recognition, including inclusion in the 2025 Gartner Magic Quadrant for AI-Augmented Software Testing Tools and The Forrester Wave: Autonomous Testing Platforms 2025.
Looking ahead, TestMu AI plans to advance toward fully autonomous AI agents, agent-to-agent testing, AI-led evaluation of AI systems, and deeper integration with codebases and developer workflows – positioning quality engineering as a continuously learning, self-governing layer within modern software development.
