MABL FOR DEVELOPERS

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.

Evas GitHub

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.

Create test-1
Create test-1

Plan, run, investigate, and fix from one conversation.

Plan

Describe the change or point at a diff and 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 the fix to the code or the test, and confirm they pass.

200x offloaded

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.

Regression

A real bug in the code

Behavior changed against known-good intent. Fix belongs in the product.

→ hand to the coding agent

Environment

A problem in neither

Timeout, flaky dependency, bad data. Nothing to change in code or test.

→ retry or route to infra

Test Issue

A stale test

The app changed on purpose; the test needs to catch up. mabl proposes the update.

→ auto-heal or confirm
