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.

Run the agent on Browser Use Cloud:

curl -X POST https://api.browser-use.com/api/v4/runs \
  -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"task": "Your task"}'

Run this in a terminal that supports bash:

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

Open the TUI:

bcode

Run an agent headlessly:

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

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 performance: claude-opus-4-8
• Best open-weight: kimi-k3
• Best value: gpt-5.6-luna at xhigh reasoning effort

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.

• 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.

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.

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.

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

Most upstream contributions belong in one of the projects BrowserCode builds on:

• Browser automation: browser-use/browser-harness
• Core coding-agent: anomalyco/opencode
