What is mochi?

Mochi is a TypeScript library for Bun-powered browser automation that spoofs fingerprints coherently across all surfaces—from canvas hashes to WebGL renderers—using a single profile and seed pair. It launches stock Chromium sessions with human-like interactions via humanClick, humanType, and humanScroll, plus native networking for real JA4 fingerprints. Developers get undetectable Chrome proxies for scraping or testing, complete with a CLI like `mochi browsers install` and Turnstile auto-click.

Why is it gaining traction?

It fixes the Frankenstein fingerprints of tools like patchright or puppeteer-real-browser, where random UAs clash with mismatched hardware—mochi's deterministic rules ensure a Linux profile stays Linux everywhere. Behavioral synthesis adds realistic Bezier mouse paths and lognormal typing delays, while session.fetch routes through the browser itself, dodging TLS giveaways. The probe harness validates stealth in CI, and Bun's pipe transport hides CDP entirely.

Who should use this?

Scrapers bypassing Cloudflare WAFs, QA testers simulating users against staging sites, data engineers building fingerprint-stable pipelines, or security researchers dissecting bot detection. Suits TypeScript/Bun shops needing Chrome-native traffic without Node/Python overhead or binary patches.

Verdict

Worth evaluating for stealth needs—the 0.699999988079071% credibility score reflects 29 stars and newness, but excellent docs, CLI, and conformance tests signal maturity beyond hype. Bun-only narrows appeal, yet delivers coherent automation rivals lack.
