mabl

What is mabl?

mabl is a test automation platform founded in 2017 by two former Google engineers who were tired of watching end-to-end test suites rot. Their answer was to build testing around machine learning: you record a test once in the browser, and mabl uses AI to keep that test passing even when the UI underneath it changes.

The whole workflow lives in the cloud. You install the mabl Trainer extension, record a user flow like a login or a checkout, and mabl replays it on its own infrastructure against every browser you care about. Because the AI understands the intent of each step rather than a fixed CSS selector, a button that moves or gets a new class does not break the test.

mabl also bakes performance checks into the same flows you already run, so you can find out that your login page got slow at the same moment you find out it still works. It is a full package for teams that want functional, visual and performance signals from one suite.

Key Features

• Record tests in the browser with the mabl Trainer extension, no code required
• Self-healing tests that repair broken steps automatically using machine learning
• Auto-generated assertions and data-driven tests from recorded actions
• Performance testing built into the same flows as functional checks
• Cross-browser execution on mabl's cloud, including Chrome, Firefox, Safari and Edge
• API testing alongside UI tests in the same project
• CI/CD integrations with Jenkins, GitHub Actions, CircleCI and more
• Rich failure reports with screenshots, video and step-by-step debugging

How to get started

Getting going with mabl is genuinely quick. Sign up for a trial, install the browser extension, and record your first flow within a few minutes. mabl watches what you click and type and turns it into a reusable test.

Once the test is recorded you can run it against multiple browsers, add assertions, and schedule it to run on every deploy. The Mabl Academy offers guided courses that take you from recorder to confident test architect.

• Create a mabl account and start a free trial
• Install the mabl Trainer extension in Chrome or Edge
• Record a user flow such as logging in or completing a purchase
• Add assertions and run the test in the cloud
• Connect your CI pipeline so tests run on every pull request

Use cases

• Regression testing before every release without maintaining brittle selectors
• Cross-browser verification for marketing sites and web apps
• Performance smoke tests that catch slowdowns early
• Testing critical journeys like signup, checkout and password reset
• Teams with limited coding skills that still need solid end-to-end coverage

Pricing and licensing

mabl is a subscription SaaS product billed on usage, with plans that scale with the number of test runs and cloud minutes you consume. There is a free trial so you can record and run tests before paying anything.

Because pricing depends on your run volume and plan tier, the current figures change over time. Check the mabl website for an up-to-date price list.

Pros and cons

The big win is maintenance. Self-healing tests plus cloud execution mean a small QA team can keep a large suite green, and the integrated performance checks give you extra signal without extra tooling. Non-programmers can contribute tests, which is rare in the testing world.

The trade-offs are control and cost. Everything runs on mabl's cloud, so there is no on-premises option, and usage-based pricing can climb for very large suites. Teams that need total control over every assertion may still prefer a hand-coded framework.
