Browser tabs
Control a real browser from inside Buda — AI Browser for an Agent-operated cloud Chromium, Local Browser for localhost and internal tools.
Sometimes the work is on the web — filling a form, scraping a page, checking a dashboard. Buda gives you two browser canvases for that: AI Browser, a real cloud Chromium the Agent can drive, and Local Browser, a lightweight embedded frame for localhost and internal URLs.
AI Browser
The AI Browser runs a real Chromium inside the Agent's cloud computer and streams its screen to your workspace over the Chrome DevTools Protocol (CDP). You and the Agent operate the same browser.
What it's for
- Watching the Agent automate web tasks in real time
- Manually navigating a site while the Agent observes
- Debugging browser automation
- Filling forms, clicking buttons, and scraping pages
Using it
Click + in the tab bar and select AI Browser. The tab connects to the sandbox browser (waking the sandbox if needed).
-
Address bar — type a URL and press
Enterto navigate -
AI instruction bar — type a natural-language instruction and the Agent performs it in the browser:
Click "Sign up" and fill the form with test data -
Direct control — click, scroll, and type on the canvas to drive the browser yourself
A status indicator shows whether the stream is connected, connecting, or disconnected; reconnect if it drops.
Local Browser
The Local Browser is a simple embedded iframe. It loads a URL directly in your browser — no sandbox, no streaming, no latency — which makes it the right tool for localhost and internal pages.
What it's for
- Viewing apps the Agent serves on a sandbox port (see Web Preview)
- Internal tools, dashboards, and documentation
- Quick reference lookups without leaving the workspace
Using it
Type a URL in the address bar and press Enter; click the reload button to refresh. Open a new Local Browser tab and it starts on the Buda docs by default.
Some sites block embedding via X-Frame-Options or Content-Security-Policy. If a page refuses to load, use Open in new tab (↗) to open it in your regular browser.
