The browser

V3Code ships its own browser, and the agent can drive anything in it — not a screenshot-and-click toy, but a Playwright-backed automation surface with dev-grade tools. The agent can navigate, read the DOM headless, take images, click through a page, work an authenticated flow, reverse-engineer a layout — it can even drive interactive pages and games. Real work on the web, not a demo.

It’s DOM-driven first (the agent targets real elements by reference and selector) with screenshots available when it needs to see the page — so it’s precise where a purely visual agent guesses.

The headline trick: it can reconstruct a website pixel-perfect — pull a live site’s build back into source you can study, clone, or rebuild from.

What the agent can do

Drive the page

open_browser / open_browser_pageurl, mobile

Open a URL — with mobile emulation when you need it — in the built-in browser.

navigate_page · click_element · type_in_page · hover_element · drag_element

Full interaction: navigate/back/forward, click (including double-click and specific mouse buttons), type text and keys, hover, and drag between elements.

handle_dialogaccept, prompt_text, select_files

Handle JavaScript dialogs and native file pickers — including selecting files for upload.

fill_formfields

Fill a whole form in one call.

See and extract

read_page · extract_page_data · screenshot_page

Read page content, pull structured data with a focus hint, or screenshot the page or a single element.

get_computed_styles · watch_page

Inspect an element’s computed CSS, or wait for the page to reach a condition before continuing.

Inspect like a developer

get_browser_console_logs · intercept_network · get_browser_network_log

Read the console, intercept requests by URL pattern (optionally with bodies), and pull the network log — the tools you’d use to understand or reverse-engineer how a site actually works.

reconstruct_page_sourcesscript_url, output_dir, method

Reconstruct a live page’s sources into files — the basis for cloning a site pixel-perfect, bundling it out of the browser, or studying how it’s built.

Go beyond the built-ins

run_playwright_codecode, timeout_ms

Run arbitrary Playwright code against the page for anything the named tools don’t cover.

save_browser_session · restore_browser_session

Save and restore a browser session, so the agent can stay logged in across runs instead of re-authenticating every time.

Why it’s more capable than a basic browser agent

Most agent browsers can click, type, and screenshot. V3Code’s adds the developer layer: network interception, console access, computed styles, session persistence, page-source reconstruction, and raw Playwright — which is what lets it reverse-engineer a page, clone a layout, drive an auth’d flow, or debug why a site behaves the way it does.
