02 PARALLEL QA / AT SCALE

Cloud execution.

Bigger runs. More agents in parallel. Faster answers across pages, user journeys, and quality dimensions—in public cloud or your private environment.

Your infrastructure. Your data. Private deployment by arrangement.

The live trial uses public cloud in either mode.

PRIVATE CLOUD/ Same QA workflowILLUSTRATIVE DEMO

A URL is all it takes to get started.

SPECIALIST AI TESTERS. ONE COORDINATED RUN.

Different journeys. Running in parallel.

Specialist AI testers. Different checks. Running together.Illustrative sessions · concurrency depends on the run

SAMPLE RESULTS · ILLUSTRATIVE ONLY

Bugs found. Fix prompts returned.

Every issue comes with evidence and a prompt your coding agent can use to fix it.

PASS / FUNCTIONALITY

Search returns relevant results

Search, refine the query, and open a result: the journey completes.

BUG / ACCESSIBILITY

Keyboard focus needs a clearer indicator

Evidence: a keyboard-only journey reaches a control without a visible focus state.

Returned fix prompt Add a visible focus indicator to the search controls. Preserve keyboard order, then rerun the keyboard-only journey to verify every control has a visible focus state.

BUG / RESPONSIVE UI

A long query clips on a narrow screen

Evidence: boundary-length input overlaps the search action.

Returned fix prompt Keep the search action visible with long input at narrow widths. Add a boundary-length input check and rerun the mobile search flow to verify no overlap.

Example outcomes to explain the report—not findings from an actual Bing test.

PUBLIC CLOUD / LIVE QA

Let's see your app.

Enter a public URL. We'll create a targeted plan and start the recommended run.

This is a public run.

The URL, screenshots, and report will be public. Don't submit private data, credentials, or sensitive pages. This trial does not provision a private cloud.

Subject to service availability and public trial limits. No payment is collected here.

LOCAL FILE / HOSTING REQUIRED

Cloud tests need a hosted page.

Cloud tests cannot run from a local HTML file. This page must be hosted on a website connected to the cloud testing service. The demos still work locally. No test has been started.

Product demos and the audience selector work without a server. No external testing page will be loaded.
