# Or: export AGENT_BROWSER_NATIVE=1
# Or: {"native": true} in agent-browser.json
```
---
## Installation
### Step 1: Install agent-browser CLI
```bash
bun add -g agent-browser
```
### Step 2: Install Playwright browsers
**IMPORTANT**: `agent-browser install` may fail on some platforms (e.g., darwin-arm64) with "No binary found" error. In that case, install Playwright browsers directly:
```bash
# Create a temp project and install playwright
cd /tmp && bun init -y && bun add playwright
# Install Chromium browser
bun playwright install chromium
```
This downloads Chrome for Testing to `~/Library/Caches/ms-playwright/`.
### Verify installation
```bash
agent-browser open https://example.com --headed
```
If the browser opens successfully, installation is complete.
### Troubleshooting
| Error | Solution |
|-------|----------|
| `No binary found for darwin-arm64` | Run `bun playwright install chromium` in a project with playwright dependency |
| `Executable doesn't exist at .../chromium-XXXX` | Re-run `bun playwright install chromium` |
| Browser doesn't open | Ensure `--headed` flag is used for visible browser |
---
Run `agent-browser --help` for all commands. Repo: https://github.com/vercel-labs/agent-browser
Install: `bun add -g agent-browser && agent-browser install`. Run `agent-browser --help` for all commands. Repo: https://github.com/vercel-labs/agent-browser

## Configuration file
Create \`agent-browser.json\` for persistent defaults (no need to repeat flags):
**Locations (lowest to highest priority):**
1. \`~/.agent-browser/config.json\` — user-level defaults
2. \`./agent-browser.json\` — project-level overrides
3. \`AGENT_BROWSER_*\` environment variables
4. CLI flags override everything
