Why traditional automation gets blocked
Modern websites employ sophisticated anti-bot systems that detect scrapers and automation tools. Headless Chrome and basic Puppeteer setups leave obvious fingerprints that trigger CAPTCHAs, blocks, and bans. Simple proxy rotation is no longer enough.
Donut Browser combines real browser profiles with anti-fingerprinting technology and a powerful automation API. Control profiles via REST API or let AI assistants drive your automation via MCP. Each profile appears as a real user, not a bot.
