Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Libretto is a toolkit for building robust web integrations by giving coding agents a live browser and a CLI to inspect pages, capture network traffic, record/replay actions, and debug workflows. It's interesting because it combines browser automation with AI-powered snapshot analysis to make automations more deterministic and helps convert UI workflows into direct API calls.

Target audience: backend devs, devops
