Browsers for AI Agents

AI agents increasingly need to use the web, not just read scraped text: navigate, click, fill forms, read what rendered, and act. That takes a real browser. BrowserCat gives your agent one over a single endpoint, with no infrastructure to run and no vendor to get locked into.

One endpoint, any framework

Agents are built on many stacks, but almost all of them speak the Chrome DevTools Protocol under the hood. Connect with whatever your agent uses, Playwright, Puppeteer, or a raw CDP client, to the same place:

const browser = await chromium.connectOverCDP(
  'wss://api.browsercat.com/connect',
  {headers: {'Api-Key': process.env.BROWSERCAT_API_KEY}},
);
// hand `browser` to your agent's tool layer

The agent drives a real, managed browser; you don’t host or scale anything.

Why a router fits agents especially well

Agent workloads are bursty and unpredictable, and the requirements shift as your agent gets smarter. A router absorbs that:

  • Managed and sandboxed. Each session is an isolated, fresh browser, important when an agent visits arbitrary, untrusted pages.
  • Scales with bursts. Spin up many sessions when the agent fans out, pay only for the browser time you use.
  • Failover built in. When a backend has a bad day, the router can route around it, so your agent keeps working.
  • No lock-in. As capabilities like proxies and alternate engines come online, your agent gains them with no rewrite. See why a router.

Practical tips

  • One session per task. Give each agent task its own browser, then close it. Clean state in, clean billing out.
  • Set timeouts. Agents can loop; cap session and navigation time so a stuck run doesn’t hold a browser open.
  • Bring a proxy when geography matters. If the agent needs a specific locale or residential IP, attach your own proxy and the router sends it to a backend that supports it.

Paying per use

BrowserCat is usage-based, so an agent that runs occasionally costs little, and one that runs constantly scales smoothly. Start on the free tier and grow from there, see the quick start to wire it up.
