The problem

Your tests pass. Your new customers still get stuck.

Tests only check what someone thought to write.

Your next customer hits the rest. They don't file a ticket. They close the tab.

How it works

Paste a URL. Get a report.

  1. 1

    Hand Tark the keys

    A staging URL and a test login. Nothing to install.

  2. 2

    Tark explores like a new customer

    It picks the goals a real customer would have and tries them in a real browser.

  3. 3

    You get proof, not a hunch

    Expected vs actual, repro count, screenshots, recording. Every time.

The agent loop, live

What Tark looks for

Three problems your test suite can't see.

  • It's broken

    Data doesn't save. An action errors. Success shows, nothing happened.

  • They can't get through

    Signup stalls. Onboarding dead-ends. The core workflow can't finish.

  • They gave up

    It works, but the next step isn't obvious. CI stays green anyway.

Tark reports what it saw, never a made-up UX score.

Evidence

Don't trust the AI. Watch what happened.

Everything a developer needs to reproduce it and fix it.

One finding from the sample run. They all look like this.

Before a finding reaches you

Anything suspicious is re-run until it reproduces, or dropped. Fewer findings. None you'll waste a morning on.

Not a test runner. A user.

Tests check what you built. Tark checks what a customer runs into. You need both.

FAQ

Before you say yes.

Short answers to what every team asks first.

Something else? Email us

Do I have to write test cases?

No. You give Tark a URL and a login. It decides what a new customer would try.

What do I need to give you?

A staging URL and a test login. One sentence about the product helps. Nothing to install.

Will it mess up my data?

It acts like a real user, so it creates things. Point it at staging.

How do I know a finding is real?

Tark re-runs anything suspicious until it reproduces. Every finding shows the count: 3/3, not “probably.”

Isn't this what Playwright or Cypress do?

Those run tests you wrote. Tark finds the paths nobody wrote tests for.

What kinds of apps?

Web apps: SaaS, e-commerce, booking, marketplaces. The beta covers signup, onboarding and the first real action. No mobile or API yet.

What does it cost?

Nothing during the beta. Your first runs are free in exchange for honest feedback.

Your next customer will find that bug. Let Tark find it first.
