Hyperbrowser
YC-backed cloud browser infrastructure for AI agents, with built-in stealth and CAPTCHA solving.
About
Hyperbrowser (S2 Labs Inc.) is a Y Combinator-backed cloud browser infrastructure platform built for AI agents and developer teams, founded in 2021 in San Francisco and backed by YC, Accel, and SV Angel. It provides scalable managed headless Chrome sessions with built-in CAPTCHA solving, proxy rotation, stealth fingerprinting, session recording, and live-view debugging, controllable via Playwright, Puppeteer, Selenium, or CDP. Browser time costs $0.10 per browser-hour billed per second, with proxy traffic at $10/GB; the Startup plan is $30/month for 25 concurrent browsers.
Alongside raw sessions it ships HyperAgent, an open-source AI-native automation framework extending Playwright with natural-language commands, an official MCP server connecting LLMs and IDEs like Claude Desktop and Cursor to the live web, and scraping/crawl APIs. In independent 2026 benchmarks it posted the fastest browser connection time among major providers.
Limitation: unlike Steel it offers no self-hosted deployment — it is hosted SaaS only — and proxies plus full stealth/CAPTCHA features require paid plans, with advanced stealth reserved for enterprise tiers. Closing all tabs ends a session even if you intended to reconnect.
