Overview

Moli by Lexmount is a cloud‑based browser service built to support AI agents and automated tasks. It offers a headless browser environment that is faster and more memory‑efficient than standard Chrome. The service can be accessed through a web playground or via its SDK and API.

The core functionality centers around three main products: Web Search, Web Fetch, and Cloud Browser. Web Search lets you send a query and receive ranked links from relevant pages. Web Fetch turns a URL into structured, readable content displayed as JSON or other formats, allowing you to extract text, links, or other DOM elements. Cloud Browser provides a programmatic API to launch a browser, perform actions, and capture outputs such as screenshots or console logs. These APIs can be used independently or combined in a single workflow.

For developers, the platform supports Playwright integration. You can connect Playwright's Chromium CDP to Lexmount with minimal changes: create a browser context, run tests, and retrieve results. The SDK documentation includes examples for Node.js. The platform also supports persistent contexts, extensions, and custom proxy configuration. You can keep browser state between sessions, useful for login flows or stateful interactions. Observability features include live session view, console logs, network snapshots, and execution evidence. Proxy limits and session IDs are exposed through the API, allowing you to route traffic through official or custom proxies.

If your task involves structured data extraction from websites, such as pulling product details, FAQ sections, or form data, Web Fetch is a direct fit. If you need broader search capabilities across the web, use Web Search. For full control over page interactions, especially when building agent workflows or automation scripts, Cloud Browser is the right choice. The playground environment lets you experiment with these features before adding them to a production build.
