Hyperbrowser

Hyperbrowser is cloud headless browser infrastructure built for AI agents, a Browser as a Service platform that runs real Chrome sessions in secure, isolated containers an agent connects to over an API. It is Y Combinator backed, founded in 2021 in San Francisco by a team including former Meta engineers, with Accel and SV Angel among its investors. The platform handles the anti bot layer, stealth fingerprinting, proxy rotation, and automatic CAPTCHA solving, so agents reach sites with aggressive bot detection, and it supports thousands of concurrent sessions with roughly one second cold starts, session isolation, recording, and live view debugging. Existing Playwright, Puppeteer, and Selenium scripts point at Hyperbrowser directly, or teams use its scrape, crawl, and extract endpoints.

Beyond raw infrastructure, Hyperbrowser ships HyperAgent, an open source, AI native automation framework that extends Playwright with natural language commands like page.ai and page.extract and an executeTask method, plus action caching to replay workflows deterministically without model calls. An official MCP server connects large language models and IDEs such as Claude Desktop, Cursor, and Windsurf directly to live web capabilities, and the platform can run agents built on Browser Use, OpenAI Computer Use, and Claude Computer Use. The HyperAgent framework, MCP server, and Python and Node SDKs are open source under the MIT license, while the hosted cloud platform is proprietary.

Pricing is credit based, where one credit is a tenth of a cent, a browser hour costs about ten cents, and a scraped page costs a tenth of a cent. A free tier includes a starting credit allowance and one concurrent browser with no card, and paid usage comes through subscription plans or direct credit purchases, with purchased credits expiring after twelve months.
