Focus On Your Code, Not False Positives
mabl writes, runs, and repairs tests on its own, letting you know in seconds whether your change is safe to ship. Auto-healing fixes flaky tests a Playwright-only setup would force you to babysit.

Your coding agent drives mabl through MCP and CLI, right from your terminal
Use mabl's agent skills in Claude Code, Cursor, or Copilot and work in plain language. Plan and build tests locally, run sessions in parallel, reproduce a failed run in a Chrome window, and confirm a passing run before you open the PR.
When a run or a deploy fails, mabl surfaces structured evidence, screenshots, and more to roll a deployment's failures into one view. Get the info in Slack, Teams, the API, BigQuery, and the MCP Server.
Manage your labels and API keys from one interface so you don't have to context switch. Configure test ID attributes so mabl anchors its finds on the stable hooks your team already ships.
Plan, run, investigate, and fix from one conversation.
The whole loop happens in your terminal, talking directly with your agent. No need to switch tools or leave your flow.
- Plan: Describe the change or point it to a diff, mabl maps what it affects.
- Run: Run only the impacted tests against your dev environment.
- Investigate: A classified verdict with the evidence behind it.
- Fix: Apply fiixes to the code or test, and confirm they pass.

Your agent runs the code. It shouldn't judge it too.
Your agent and CI build and deploy the changes. Meanwhile, mabl orchestrates the tests and delivers the verdict, independent of the code that wrote it. This means your agent isn't grading its own work, so you avoid the kind of false positives an agent pushes. And because the token-heavy judging runs on mabl, not your agent, you get the verdict for a fraction of the tokens, time, and cost.
Know what a failure means before you touch it
mabl tags each failure and hands your coding agent the evidence it needs to act, so you skip the triage time-suck and stay on track.
A real bug in the code
Behavior changed against known-good intent. Fix belongs in the product.
Hand to the coding agent
A problem in neither
Timeout, flaky dependency, bad data. Nothing to change in code or test.
Retry or rout to infra
A stale test
The app changed on purpose; the test needs to catch up. mabl proposes the update.
