Handling the web infrastructure for the world's most active data teams
Two powerful ways to control the browser
bro has two command types:
autopilotAI-powered commands that autonomously navigate, interact, and extract data in 90+ languages.
and manualDirect browser commands that give you control over navigation and page state.
.Use autopilot commands like
actExecutes a complex instruction autonomously. The AI plans and performs a sequence of actions.
and extractExtracts structured data directly from the current page layout using AI.
when you want bro to handle the flow for you.Use manual commands like
get_screenshotCaptures a full page or viewport screenshot.
, get_htmlReturns the current HTML content of the page.
and click_atMoves the cursor to the target coordinates and clicks the specified mouse button.
when your pipeline should drive each step itself.Same browser. Two ways to run it.

bro handles the flow
Every browser action is fully handled
When you tell bro to execute a command, it handles the chaotic parts in the background:
- handles page load errors and timeouts
- manages iframes and shadow dom
- keeps the session in a single tab
- routes browser network traffic
- and many other things you don't want to care about
Focus on the task, not browser babysitting.
POST/get_screenshot
Command
get_screenshot
Manual command: Captures a screenshot of the current page based on the requested mode.
Parameters
mode→"viewport"
Method that'll be used to capture.
viewport: captures currently visible part of the page.
full_page: captures full-length image.
viewports: captures viewport images.
viewport: captures currently visible part of the page.
full_page: captures full-length image.
viewports: captures viewport images.
viewport_min→0
Sets the starting index (0-based) for the captured viewports. Useful for skipping the top of the page.
viewport_max→50
Sets the maximum amount of viewports to capture. Max limit is 50.
Engine Execution
verify page load
Waits for DOM and network idle, checks scroll height to ensure the page is fully rendered before capturing.
calc viewports
Calculates total viewports based on actual page scroll height and requested viewport ranges.
capture
Default Chrome screenshot method misses out-of-viewport iframes content. We dynamically scroll and iterate through viewports to capture everything seamlessly if we spotted an iframe on the page.
stack & verify
Combines multiple viewport screenshots into one complete, seamless full-page image (if specified in the mode).
resize
Scales the final stitched image to fit optimal storage and AI processing requirements.

bro handles parts of the web that resist automation.
With clean fingerprints, human-like behavior and adaptive network routing your agents look like a real users.
We tested bro on 400 the web’s most aggressively protected sites, comparing access rates with leading Cloud Browser providers and open-source solutions.
83.5%
Stealth features and proxies were always enabled, and standalone CAPTCHA solving was disabled across bro and all competing browsers.
These tests show how browsers can access sites passively — without executing any actions to solve CAPTCHA.

Tune the browser for speed, reliability or cost
Choose how bro runs before the session even starts to find the perfect balance between cost and ability to bypass anti-bot verification:
Proxy tiers: customize IP qualityBasic: Standard residential network.Premium: Higher-quality network for strict anti-bot protections.Proxy routing: pay only for the traffic you needhtml_only: Proxies only HTML documents.basic: html_only + XHR and WebSockets.extended: basic + JavaScript files.full: Routes all traffic through the proxy.AI settingsChoose between small, medium or large models for autopilot depending on the complexity of your task.: scale intelligence based on the taskCookiesPass your own authenticated session cookies to bypass login screens.: seamlessly resume authenticated sessions
Go lighter when the task is simple or turn on stronger proxy routing when the site is protected and reliability matters more than cost.
