Moli by Lexmount is a browser engine built from scratch for AI agents, designed to start faster and use less memory than Chrome. It powers Lexmount Browser, a cloud browser platform where teams can run multiple isolated browser sessions with proxy support while infrastructure is managed for them. Agents can browse, fill out forms, and extract data via the Playground or SDK, and developers can also connect AI agents and Playwright through the Cloud Browser API and Web Fetch API for structured web content extraction.
