Show HN: Libretto – Making AI browser automations deterministic
Summary
Libretto is an open-source toolkit by Saffron Health for building robust browser automations with a live browser, token-efficient CLI, and AI-assisted analysis. It enables inspecting pages, capturing network traffic, recording and replaying user actions, and debugging workflows against real sites, with use cases ranging from one-shot script generation to converting UI automation into direct network requests. The project emphasizes deterministic browser automation and integration maintenance for complex workflows, including healthcare software.
