Drop-in compatible
Change one line. Get routing, failover, and pooling for free.
import { chromium } from "playwright-core";
// One line change — route through the gateway
const browser = await chromium.connectOverCDP(
"http://localhost:9500"
);
const page = await browser.newPage();
await page.goto("https://example.com");
console.log(await page.title());
await browser.close();Drop-in replacement. Change the URL, keep everything else.
Give every agent
a browser.
No setup required.
The built-in MCP server auto-detects Chrome on your system, launches it on first use, and gives AI agents 8 browser tools through the gateway's routing layer.

5 Routing Strategies
Priority chain, round-robin, least-connections, latency-optimized, and weighted distribution.
Automatic Failover
Provider goes down? Next one picks up instantly. TTL-based cooldowns with auto-recovery.
MCP Server
8 browser tools for AI agents. Navigate, screenshot, snapshot, interact, evaluate. Zero config.
Request Queue
All providers busy? Connections wait in a FIFO queue instead of failing. Configurable timeouts.
Concurrency Limits
Set maxConcurrent per provider. The gateway enforces it so providers never get overwhelmed.
Session Persistence
Disconnect and reconnect to the same browser. Cookies, localStorage, and page state preserved.
Web Dashboard
Manage providers, view live sessions, edit config, monitor health — all from the browser.
Health Monitoring
Periodic connectivity probes detect unhealthy providers. Cooldown system skips failing ones.
Webhooks
Get notified when providers go down, recover, enter cooldown, or when the queue overflows.
Protocol Agnostic
Works with CDP, Playwright protocol, WebDriver BiDi — raw TCP pipe forwards any WebSocket protocol.
Developer experience
From zero to routing in seconds
Built in the open.
MIT licensed.
No vendor lock-in. Fork it, self-host it, extend it. Your infrastructure, your rules.
