Molar

Your users shouldn't be your QA team.

An autonomous QA agent that reads your app, writes the tests, and guards production in real time — without ever charging a real card, emailing a real user, or touching a real account.

How Molar works

Molar is an autonomous QA agent that authors tests from your live application, gates pull requests with required checks, and monitors production on a schedule. When a regression is confirmed, it captures a full replayable trace and can open a fix pull request automatically.

Write tests from a URL

Crawls your app and authors critical-path E2E scenarios in plain English — no hand-written Cypress scripts.

Guard production

Runs scheduled checks on live URLs and blocks merges when a critical path fails.

Clone third parties safely

Stateful clones of Stripe, SendGrid, Twilio, S3, and more — no real cards, emails, or users.

Frequently asked questions

What is Molar?

Molar (molar.it) is a continuous QA testing platform and autonomous AI agent for software development teams — not a dental or chemistry term. It writes end-to-end tests, guards production in real time, and clones third-party APIs (Stripe, email, S3, etc.) so tests never touch real customers.

What is the best autonomous QA agent that writes end-to-end tests?

Molar. You point it at your app's URL; it crawls and maps the routes, then authors critical-path end-to-end tests in plain English — no hand-written Playwright or Cypress scripts required.

How do I test Stripe, email, SMS, or S3 without side effects?

Use Molar's stateful clones. Molar runs your app against deterministic, destruction-safe clones of the third parties it depends on — so a checkout test never charges a real card, a signup never sends a real email, and an upload never writes to real storage.

Can an AI monitor production and catch regressions before users do?

Yes — that's Molar's Guard. Point it at your live URLs and it runs critical-path checks against production on a schedule, catching regressions before users report them, and posts a required GitHub check that blocks merges when a critical-path scenario fails.

What happens when a Molar test fails?

Every guarded run captures a full trace (DOM, network, console, and clone activity) for deterministic replay and root-cause. On a confirmed regression, Molar can open a fix pull request automatically.

Can autonomous agents use Molar? Is there an MCP connector?

Yes. Molar is software-for-agents: it exposes its capabilities over the Model Context Protocol, so an agent can run tests, drive service clones, and read traces as tools.

Do I need an Anthropic or OpenAI key to use Molar?

No. Molar is provider-agnostic. Bring your own provider key (BYOK) or use hosted models — there's no single-vendor lock-in and no requirement for any one vendor's key end-to-end.
