Mabl
AI-powered no-code test automation for web, mobile & APIs
What is Mabl?
Try Mablmabl is an agentic test automation platform that writes, runs, and repairs tests so you can ship with confidence. It’s built to reduce false positives by keeping test “verdict” work on mabl rather than relying on the same coding agent that made the change. For developers, it supports driving mabl from your terminal via MCP and CLI, plus workflows for planning, running impacted tests, investigating categorized failures, and fixing and re-confirming results.
What does mabl do to help developers ship changes safely?
mabl writes, runs, and repairs tests automatically, so you can quickly tell whether a change is safe to ship. It also focuses on reducing false positives by orchestrating the testing and verdict process independent of the agent that authored the change.
How does mabl handle flaky tests and test repairs?
mabl auto-heals flaky tests, reducing the need to babysit a Playwright-only setup. When tests fail, it provides a classified verdict with the evidence behind it, so you can address real regressions and update stale tests when the app changes.
Can I run mabl from my terminal using an AI coding assistant?
Yes—mabl can be driven through MCP and CLI directly from your terminal. It also supports agent skills in Claude Code, Cursor, or Copilot, where you can plan and build tests in plain language.
What’s the workflow for planning, running, investigating, and fixing tests?
You can describe the change (or point to a diff) and mabl maps what it affects, then run only the impacted tests against your dev environment. After that, you investigate with a classified verdict and evidence, apply the fix to code or the test, and confirm everything passes.
Does mabl integrate with CI/CD, such as GitLab merge request checks?
Yes. mabl integrates with GitLab CI/CD so you can run tests in your pipeline and use merge request checks, with results appearing in the corresponding pipeline stage. The integration includes a mabl CLI image to run without extra infrastructure.
Is there a free trial and how does cloud testing billing work?
mabl offers a 14-day free trial. Cloud testing uses a usage-based credit consumption model based on cloud test runs, while local test runs are free.
