Molar — autonomous QA testing platform
The Molar QA agent writes tests
and guards production.
Molar (molar.it) is an autonomous QA agent for software development teams — not a dental or chemistry term. Point it at your app's URL: it maps critical paths, authors end-to-end tests in plain English, and runs continuous production checks with sandboxed emails, virtual cards, and cloned third-party APIs.
01 — Definition What is the Molar QA agent?
The Molar QA agent is an AI-powered software testing agent that replaces manual test authoring and brittle Playwright maintenance. Instead of hand-writing scripts, you give Molar a URL. It crawls your application, understands how users move through it, and maintains a living suite of critical-path end-to-end tests.
The same agent guards production on a schedule — catching regressions before customers report them — and can open a fix pull request when a check fails with a full replayable trace.
02 — Capabilities What the QA agent does
- Autonomous test authoring — crawls your app and writes critical-path E2E tests from a URL.
- Continuous production guard — scheduled checks against live URLs; required GitHub check on failure.
- Stateful third-party clones — Stripe, SendGrid, S3, Twilio, GitHub, Slack and ~28 more, with no real charges or emails.
- Trace capture & replay — DOM, network, console, and clone activity for root-cause.
- Auto-fix (Mender) — opens a fix PR on confirmed regressions.
- MCP connector — other autonomous agents can run tests and read traces as tools.
03 — Comparison Not a test runner. A release guard.
Traditional QA tools expect you to write and maintain scripts. Synthetic monitoring pings one URL. Molar is an autonomous QA agent that owns the full loop: discover flows, write tests, gate PRs, shadow deploys, and watch production — with destruction-safe clones so checkout tests never charge a real card.
