How it browses
- A real, visible browser. BOR launches Chrome (or the bundled Chromium) headed by default, with its own persistent profile — separate from your personal browser, so its logins and cookies don’t touch yours.
- It reads pages structurally. After every action, BOR gets an accessibility snapshot of the page — every link, button, and field, precisely identified. It acts on elements by reference, not by guessing coordinates.
- It does real work. Clicking, typing, key presses, dropdowns, multi-field form fills, tab management, going back, waiting for content, and taking screenshots when it needs to actually look at something.
- It can stay signed in. Because the profile persists, you can log BOR’s browser into your sites once (use “Open sign-in browser” from the connectors gallery) and it stays logged in for future tasks.
- Verified before claimed. BOR re-reads the page after acting, so “I’ve submitted the form” means the form was actually submitted — not just that a click was sent.
What to say
- “Find the cheapest direct flight to Lisbon in September.”
- “Log into my electricity account and tell me the last bill.”
- “Fill out this signup form with my details.”
- “Compare the pricing pages of these three tools.”
Quick lookups: search and fetch
Not everything needs a browser session. BOR also has:- Web search — ranked results with sources, rendered as a card in the bubble. This is how it gives sourced answers and researches before building.
- Web fetch — read a specific URL’s content directly.
Fallbacks
- browser-use CLI (optional). If you’ve installed the browser-use CLI, BOR detects it and can use it as a fallback backend — it attaches to your actual running Chrome (your real profile, cookies, and tabs) over CDP. This is entirely optional; nothing in BOR requires it, and without it the ambient browser handles everything.
- Computer use. For the rare page that defeats structural reading, BOR can fall back to driving a visible browser with screen capture and clicks.
The Browser app
Separate from all of the above, BOR can open a plain Chrome window for you to use — the user-facing Browser app, with its own profile, distinct from the automation profile. Ask “open a browser” when you just want to look at something yourself.Configuration
Environment overrides, if you need them:BOR_BROWSER_HEADLESS=1 (run the ambient browser headless), BOR_BROWSER_EXECUTABLE_PATH (a specific Chrome/Chromium binary), BOR_BROWSER_CHANNEL=chrome (browser channel), BOR_BROWSER_VIEWPORT (viewport size, default 1440x1000). npm run browser:install installs the bundled Chromium if you don’t have Chrome.
