Show HN: Notte – Full-stack web-agent framework (open-source)

Hi HN,

This is Lucas, one of the creators of Notte.

Notte is an open-source full-stack framework for web agents, designed to be fast and reliable in production.

Our tech revolves around a perception layer that translates the DOM to natural language, allowing LLMs to reason and act upon it reliably. This allows observation of website states and execution of actions using intuitive natural language commands.

The goal with Notte is to ultimately be production-ready for a wide range of workflows.

Notte can be used via a unified API, and includes unified session management, secure vault (payment, creds, keys, cookies, OTPs), built-in stealth, async agent/browser execution, stateful sessions, agent personas (email, phone, identity vault), as well as built-in retry logic and session replay.

We also have captcha pause + HITL integration, as well as an MCP package, plus some cool features for scrapers (JSON schema-driven scraping helpers). All via Python SDK & API.

We’d love to get feedback on:

Is there anything missing before you’d try or trust it on certain workflows? Any edge cases we might have missed? ...or just any general feedback from the HN community.

Let us know what you think!
