DevTools audit for interactive states

Find agentic browsing issues hiding inside interactive UI states.

Agentic Browsing Audit checks dialogs, menus, drawers, popovers, form errors, checkout steps, and other interactive UI states for agentic browsing issues that a standard Lighthouse scan may not capture.

Agentic browsing testing

Use the extension when the UI only appears after a click.

Standard page-load scans help, but they cannot inspect every dialog, drawer, menu, validation error, or checkout step. The extension lets your team open the state first, then scan the browser exactly as it is.

Dialogs

Dialog names, focus containment, close buttons, form fields.

Dropdowns

Expanded state, selected values, keyboard paths, readable options.

Drawers

Background inertness, navigation boundaries, checkout side panels.

Forms

Validation errors, field labels, descriptions, confirmation messages.

Problem

Page-load scans miss the UI people actually use.

Many agentic browsing issues sit behind JavaScript state: account menus, checkout drawers, validation messages, bottom sheets, dropdowns, and dialogs that only appear after someone clicks, types, or opens something.

1

Some agent-facing UI only exists after a click

A page-load scan may inspect the first screen but never open the dropdown, trigger the form error, reveal the modal, or inspect the drawer where the broken control lives.

2

Agentic browsing depends on state

Browser agents need readable names, roles, focus, errors, and confirmations after each action. The first screen can look clean and still fail once the UI changes.

3

Developers need the exact moment

Give them the URL, timestamp, affected element, selector, screenshot, issue details, and fix guidance in one report so they can reproduce the problem.

Features

What the extension records

Use the extension while you operate the page. Each scan checks the current browser state and adds the affected elements to the same audit session.

Manual scan for the current state

Log in, create an audit session, open the dialog, dropdown, drawer, menu, hover state, or validation state you want to test, then scan it.

Find agentic browsing issues after the page changes

Check labels, roles, dialog names, focus behavior, form errors, and other agentic browsing issues that appear only after JavaScript changes the page.

Manual and auto scan modes

Scan manually as you open each state, or turn on auto scan so the extension watches user interactions and scans after the page settles.

Issue groups with examples

Open an issue group, then move through affected elements with timestamps, URLs, selectors, screenshots, and fix guidance.

Reports your team can use

Generate a hosted report with agentic browsing issue groups, affected elements, selectors, screenshots, scan context, and fix guidance.

Screenshots for fragile states

Capture states that are easy to lose, including dropdowns, tooltips, short-lived validation messages, and flows that change after navigation.

Workflow

How an agentic browsing audit works

Open the Chrome extension, use the website normally, and scan each state manually or with conservative auto scan before generating the report.

01

Install and log in

Install the Chrome extension, open DevTools on the page, select the Agentic Browsing Audit tab, and log in with your CanAgentUse account.

02

Create a session and choose scan mode

Create an audit session, then use manual scan when you want control or enable auto scan while you interact with the page.

03

Scan, review, and report

Scan interactive UI states, review grouped agentic browsing issues with affected-element evidence, then generate a report with recommended fixes.

Report output

Each scan keeps the agentic browsing details developers need.

The report keeps issue details, affected selectors, state names, scan timing, and fix guidance in one place. Developers can reproduce a dialog bug or form error without asking someone to remember what they clicked.

Trust

Made for real browser workflows

You choose what to test

You decide which states matter. The extension scans the state you reveal and ties the evidence to the browser moment where the issue appeared.

Works for product and QA teams

Design systems, checkout flows, SaaS dashboards, account pages, and support forms can all be tested without a custom crawler.

Paired with CanAgentUse reports

The extension turns interactive-state scans into reports with agentic browsing issue groups, affected elements, screenshots, and fix guidance for developers.

Chrome Web Store

Install the extension from the Chrome Web Store.

Start with the flows people rely on: signup, checkout, account settings, search filters, support forms, and any UI that changes after a click or navigation.

FAQ

Questions teams usually ask

Why use the extension instead of a normal scan?

Normal scans see the loaded page. The extension lets you reveal interactive states first, then scan the exact dialog, menu, drawer, dropdown, hover state, or validation error.

Does the extension click through the site automatically?

It can help with auto scan, but the workflow is still tester-led. You operate the site, choose the states to test, and can scan manually whenever the right state is visible.

Where do reports go?

Generated reports are saved to your CanAgentUse account so you can review agentic browsing issue groups, share affected elements, and give developers fix guidance.
