mabl

mabl is an AI-native test automation platform that lets software teams create, run, and maintain tests across web, mobile, API, accessibility, and performance without extensive scripting. Its multi-model AI approach, combining traditional machine learning and generative AI, powers auto-healing tests that adapt automatically as an application's UI changes, cutting the maintenance burden that typically slows down automated test suites.

TestMu AI

TestMu AI, rebranded from LambdaTest in January 2026, is a cloud-based testing platform that runs automated and manual tests across more than 3,000 real browser and OS combinations and over 10,000 real mobile devices. It supports popular frameworks including Selenium, Cypress, Playwright, and Appium, plus visual regression testing through its SmartUI tool. The rebrand adds agentic AI features on top of the existing cloud testing infrastructure: Kane AI generates and maintains tests from natural-language descriptions, HyperExecute orchestrates faster test runs, and Test Intelligence surfaces AI-driven analytics on failures. The company says it serves 3 million-plus users across 18,000-plus companies, including Microsoft, OpenAI, and Nvidia.

QA Wolf

QA Wolf is an AI-driven end-to-end testing platform that combines a "Mapping AI" which autonomously explores a web or mobile app to document its workflows, with an "Automation AI" that generates production-grade Playwright or Appium test code from that map. Tests run on QA Wolf's pre-warmed, fully parallel infrastructure so large suites finish in minutes instead of hours. Beyond the self-serve platform, QA Wolf offers a "Coverage as a Service" option where its own QA engineers build, run, and maintain the full test suite, investigate failures within 24 hours, and guarantee zero flaky tests. Because generated tests are standard open-source Playwright and Appium code, teams aren't locked into a proprietary test format if they later want to run tests elsewhere.

Katalon

Katalon is a test automation platform used by QA teams to plan, author, run, and fix tests across web, mobile, API, and desktop applications from a single workspace. It combines a low-code Test Automation Studio with a suite of AI agents that can generate test cases, run tests autonomously, and analyze failures. The platform includes Test Execution Cloud for running tests across real browsers and mobile devices, Production Insights for post-release monitoring, and reporting dashboards with real-time analytics. Katalon integrates with CI/CD pipelines, Jira, Azure DevOps, and other development tools, and is used by more than 120,000 users across industries like banking, retail, and healthcare.

TestComplete

TestComplete is an automated testing platform from SmartBear that lets QA teams create and run UI tests for desktop, web, and mobile applications from a single tool. It runs as a Windows-based thick client, which suits organizations that need offline testing or deployment on secure, air-gapped internal networks.

Testim

Testim is an AI-powered test automation platform, owned by Tricentis, that helps teams create and maintain automated tests for web applications, mobile apps, and Salesforce environments. It lets users describe testing needs in natural language and uses AI to build tests, then relies on smart, ML-based locators that keep tests working even as the underlying application changes.
