The browser-native agent

A streamlined coding agent that drives real browsers through unconstrained CDP.

The unbounded power of the browser working seamlessly with your code. The agent adapts to every site at runtime and writes scripts to reuse later.

Hosted

Want to skip the setup? Use BrowserCode in Browser Use Cloud.

One-Line Install

Run this in a terminal that supports bash:

curl -fsSL https://bcode.sh/install | bash

Usage

Open the TUI:

bcode

Run an agent headlessly:

bcode run "On Google flights return all flight details from New York to SF tomorrow"

Connect an LLM

Performance of LLMs with BrowserCode on BU Bench V1

BrowserCode supports any model you can reach with an API key, plus every provider OpenCode supports.

Use /connect in the TUI, or set provider API keys in your environment.

Recommended models from current BU Bench evals:

Best score: claude-opus-4-7
Best speed: gpt-5.5
Best open-weight: glm-5.2
Best value: gemini-3.1-pro-preview
Lowest cost: minimax-m3

Connect a Browser

Let the agent connect for you. It knows how.

You can prompt:

Connect to my current tab on amazon.com and find deals for 64GB DDR5 RAM, return URLs

The agent will take control of your actual browser.

Make a new browser profile and QA test http://localhost:3000, fix bugs and open a PR

The agent will work locally in its own browser profile.

Open a remote browser and extract every item sold on mcdonalds.com in SF

The agent will control a Browser Use Cloud browser and give you a link to watch it.

Cloud Browsers

Browser Use Cloud offers unlimited free browsers, limited to 3 concurrent sessions, with stealth, captcha solving, and proxies.
Just set BROWSER_USE_API_KEY in your environment. The agent can sign up completely autonomously; just ask it to. To upgrade further, go to cloud.browser-use.com.

Philosophy: do more with less

Browser ability and code-writing ability are deeply connected.

We turned browser interaction into a coding problem; the agent writes JavaScript that drives Chrome directly through CDP. Minimal abstractions. Maximal power to the agent.

BrowserCode outperforms every browser agent we have tested it against.

Architecture

BrowserCode is a fork of OpenCode with a vendored TypeScript port of Browser Harness.

It adds one core browser primitive:

browser_execute(code)
  -> runs JavaScript in-process
  -> talks to Chrome through the DevTools Protocol
  -> keeps the browser session alive across calls
  -> returns logs, values, and screenshots to the agent

Reusable browser scripts are written to:

.bcode/agent-workspace/

BrowserCode is not built by the OpenCode team and is not affiliated with OpenCode in any way.

Telemetry

BrowserCode sends anonymous usage traces to help improve the project. To opt out, set DO_NOT_TRACK=1 in your environment.
