# agent-browser Environments
|
|
|
|
A demo of agent-browser running in a Vercel Sandbox. Enter a URL and take a screenshot or accessibility snapshot.
|
|
|
|
## How It Works
|
|
|
|
The app runs agent-browser + Chrome inside an ephemeral Vercel Sandbox microVM. A Linux VM spins up on demand, executes agent-browser commands, and shuts down. No binary size limits, no Chromium bundling complexity.
|
|
|
|
## Getting Started
|
|
|
|
```bash
|
|
cd examples/environments
|
|
pnpm install
|
|
pnpm dev
|
|
```
|
|
|
|
## Sandbox Snapshots
|
|
|
|
Without optimization, each Sandbox run installs agent-browser + Chromium from scratch (~30s). A **sandbox snapshot** is a saved VM image with everything pre-installed -- the sandbox boots from the image instead of installing, bringing startup down to sub-second. (This is unrelated to agent-browser's *accessibility snapshot* feature, which dumps a page's accessibility tree.)
|
|
|
|
Create a sandbox snapshot by running the helper script once:
|
|
|
|
```bash
|
|
npx tsx scripts/create-snapshot.ts
|
|
# Output: AGENT_BROWSER_SNAPSHOT_ID=snap_xxxxxxxxxxxx
|
|
```
|
|
|
|
Add the ID to your Vercel project environment variables or `.env.local`. Recommended for production.
|
|
|
|
## Environment Variables
|
|
|
|
| Variable | Description |
|
|
|---|---|
|
|
| `AGENT_BROWSER_SNAPSHOT_ID` | Sandbox snapshot ID for sub-second startup (see above) |
|
|
| `KV_REST_API_URL` | Upstash Redis URL for rate limiting (optional) |
|
|
| `KV_REST_API_TOKEN` | Upstash Redis token for rate limiting (optional) |
|
|
| `RATE_LIMIT_PER_MINUTE` | Max requests per minute per IP (default: 10) |
|
|
| `RATE_LIMIT_PER_DAY` | Max requests per day per IP (default: 100) |
|
