Notte
Browser platform and framework for AI web agents
Notte provides cloud browser sessions with anti-detection, residential proxies and CAPTCHA solving, plus browser agents that navigate sites from natural-language tasks. It can deploy browser automations as serverless functions with cron scheduling, and offers personas and secret vaults so credentials stay away from the LLM. It has an MCP server, a CLI and an agent skill for coding agents. The site says it is backed by Y Combinator (W25).
