We've been building browser infrastructure since 2012 — powering cross-browser testing for 2.5M+ developers at companies like Microsoft, OpenAI, and NVIDIA. Today we're launching something we've been quietly building for the last year: Browser Cloud.

The problem we kept seeing

AI agents that interact with the web — scrapers, workflow bots, computer-use agents — all hit the same wall. They need a real, production-grade browser. Not a localhost headless instance that gets blocked after 10 requests. Not a sandbox that drops session state. A browser that behaves like a real user, scales to hundreds of parallel sessions, and doesn't fall over at 2am.

Browserbase and Steeldev exist in this space. They're good products. But they were built by teams that started with the browser layer. We started with a decade of enterprise-grade testing infrastructure beneath it — and Browser Cloud is what happens when you build the agent browser on top of that foundation.

What Browser Cloud does

Spin up hundreds of headless browsers on demand via SDK. Sub-second cold start. Sessions that run up to 24 hours.

Built-in from day one:

• Stealth mode — fingerprint masking, CAPTCHA solving, ad blocking. Your agents stay undetected.

• Session persistence — cookies, local storage, and login state transfer across runs. Log in once, stay logged in.

• 180+ geolocations — every request looks local. No proxy gymnastics.

• Built-in localhost tunnel — reach internal apps behind firewalls without extra tooling. This one is unique to us.

• Full observability — live views, video replays, complete network and console logs. See exactly what your agent saw.

Framework-agnostic: Playwright, Puppeteer, Selenium, or wire your agent in directly via SDK.
