Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 8)

Mochi.js is a Bun-native browser automation library focused on undetectable fingerprinting by deriving all surfaces from a single profile-seed pair, routing network traffic through Chromium itself, and using biomechanical models for human-like interactions. Its innovative relational matrix and coherent design approach to browser automation fills a known gap for stealth-oriented scraping and testing.

Target audience: backend devs, data engineers, security researchers
