Libretto

Libretto is an open-source CLI that lets agents turn website workflows into fast, reusable scripts you can deploy The problem: Most browser automation tools work by sending an AI agent to operate a website in real time, like a robot typing and clicking on your behalf. This is slow, expensive, and unpredictable. They rely on fragile DOM parsing that breaks on legacy and complex sites, and you can never fully trust what the agent will do on unintuitive or inconsistent workflows. Our approach: Libr
