Libretto
Turn website workflows into reliable APIs
Libretto is a business in healthcare based in San Francisco, CA, USA, founded in 2023.
Profile
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: Libretto helps your coding agents generate workflows as actual, readable code during development, not at runtime. Under the hood it combines Playwright with direct in-session network/API calls for reliability and bot detection evasion. It also supports step-through debugging and a read-only mode to prevent accidental data changes while your agent builds and debugs workflows.
This makes Libretto cheaper, faster, and easier to maintain, especially for more complex websites and high stakes workflows.
