About Notte
Notte is an open-source framework for building and deploying reliable web automation agents. It combines AI-driven agent reasoning with traditional scripting to maximize efficiency, cutting costs by 50%+ while improving reliability. The framework offers an open-source core for running web agents with natural language task execution, structured output via Pydantic models, and Playwright-compatible site interactions. An optional API service adds stealth browser sessions with CAPTCHA solving, hybrid workflows, secrets vaults, and digital personas. Users can develop locally with their own LLM keys and then seamlessly deploy to production using the Notte API.
