Hyperbrowser
Cloud browsers, sandboxes and web data APIs for AI agents
Hyperbrowser hosts cloud Chrome sessions that can be controlled with Playwright or Puppeteer, with persistent logins and live inspection. It also offers isolated sandboxes with snapshots and a web API for fetching, crawling and search that returns Markdown, HTML, screenshots or JSON matching a schema. Agent tasks can be run with HyperAgent, Browser Use or computer-use models, and the service ships Node.js and Python SDKs, a CLI and MCP.
