Web application testing without the maintenance burden
mabl authors end-to-end web application tests from descriptions or user flows and keeps them current as your UI evolves, automatically.

Every layer of your web application, continuously tested
From authentication flows to complex multi-step transactions, mabl covers the critical paths your users depend on and keeps them working.

Author tests in natural language
Author complex web application tests from a prompt, user stories, or acceptance criteria — including tests with MFA, inline API calls, conditional logic, accessibility checks, and file verification.
Hands-off test maintenance
When your UI changes, mabl uses the element history to find candidates and summarizes the find confidence for full traceability.


One test, executed across browsers
Run tests across Chrome, Firefox, Safari, and Edge. mabl surfaces browser-specific failures and distinguishes real compatibility issues from test infrastructure noise.
Failures analyzed in plain language
mabl examines screenshots, logs, and run history to classify the result and suggest a next step. Ask follow-up questions directly in the results view to dig deeper with no log hunting required.

Identify visual regressions
Catch unintended UI changes before they reach users. mabl compares screenshots across runs and surfaces visual diffs that fall outside expected thresholds.
Integrate web tests into your pipeline
Run web tests on every pull request with GitHub, GitLab, or Jenkins. Status checks block merges when critical paths fail. Results appear directly in your coding agent and PR.

Web coverage that builds, runs, and fixes itself
mabl keeps your end-to-end web application tests working continuously, creating coverage from your inputs, running tests on a schedule, analyzing every failure, and maintaining tests when your app changes.
