Libretto – Making AI browser automations deterministic

Saffron Health has open-sourced Libretto, a toolkit that gives AI coding agents a live browser and efficient command-line interface to build reliable web automations by inspecting pages, capturing network traffic, recording user actions, and debugging workflows interactively. The tool addresses the challenge of maintaining browser integrations by enabling agents to reverse-engineer APIs, convert browser scripts to direct network requests, and autonomously fix broken automation scripts.
