Open core full stack framework and browser infrastructure for building, deploying, and scaling reliable web agents, using a perception layer that turns webpages into natural language action maps.

Notte, a Y Combinator company from Notte Labs, is an open core, full stack framework and browser infrastructure for building, deploying, and scaling reliable web agents through a single application programming interface. Its signature idea is a perception layer that transforms webpages into structured, navigable maps described in natural language, an action interface in text. This lets language models read, understand, and act on sites without fragile CSS or XPath selectors, and reduces their cognitive load enough that smaller, faster, cheaper models can drive accurate automation. The framework pairs AI agents with traditional scripting so developers script deterministic parts and use AI only where needed, cutting cost while improving reliability.

As infrastructure, Notte ships managed cloud browser sessions on a global edge network for low latency, plus serverless browser functions that colocate compute next to the browser, described as AWS Lambda for browser work. It handles the operational hard parts out of the box: proxies, CAPTCHA solving, anti detection, browser profiles, and an encrypted secrets vault where agents fetch credentials at runtime rather than hardcoding them. It is compatible with Playwright, Puppeteer, Selenium, browser-use, Stagehand, and anything that connects over the Chrome DevTools Protocol, in Python or TypeScript.

Notte is model agnostic, working with OpenAI, Anthropic, Gemini, and others, and developers can bring their own keys with token pricing passed through at no markup or select the reasoning model per agent. Extensibility is a strength: alongside the open source framework and software development kits, Notte publishes a Model Context Protocol server that connects language models directly to its cloud browser. For observability it offers live view screen sharing, session replays, live debugging in a browser based studio, and production monitoring, and it publishes open browser agent benchmarks like open operator evals.

The platform is SOC 2 Type II certified and can run as a managed cloud service or be self hosted from its source available codebase, and it supports bringing an external browser provider over the Chrome DevTools Protocol. Its main current gaps are that a first class persistent agent memory and a shipped human in the loop workflow remain on the roadmap, and it is a developer framework rather than a marketplace of prebuilt agents. For engineering teams building production web automation, it is a fast, cost efficient, and well instrumented foundation.

Use cases & customers

In practice

A developer builds a flight search agent. Using Notte's perception layer, the agent reads Google Flights as a natural language action map, fills the form, and runs the search reliably with a small model, deployed as a serverless function.

A data team needs structured extraction at scale. They call Notte's scraping endpoint with a schema, turn target pages into machine readable JSON, and run it on managed cloud browsers with proxies and CAPTCHA solving handled automatically.

An engineering team wants an agent driven from Claude. They connect through Notte's Model Context Protocol server, letting the assistant execute web tasks on Notte's cloud browsers while credentials stay in the encrypted secrets vault, never hardcoded.

Open-core full-stack WEB AGENT FRAMEWORK + browser infrastructure. Notte Labs, Inc. YC S25. Founders Andrea Pinto, Lucas Giordano. SSPL-1.0 license (source-available/self-hostable) + cloud-hosted. SIGNATURE: PERCEPTION LAYER — transforms webpages → structured navigable maps in natural language (action-API-in-text), eliminates fragile CSS/XPath selectors, reduces LLM cognitive-load → use smaller/faster/cheaper models. Observe/Step/Scrape primitives (Playwright-compatible + NL). Combines AI-agents + traditional-scripting (script deterministic parts, AI only when needed — cuts cost 50%+). Single API, Python + TypeScript SDK (notte_sdk). INFRA: managed cloud browser sessions (headless+headful) on global edge network (zero-latency), serverless browser functions ('AWS Lambda for browser work', colocate compute), CDP/Playwright/Puppeteer/Selenium/browser-use/Stagehand compatible.
