Score: 3.7/10 (Innovation: 3, Technical: 3, Documentation: 5, Utility: 5)

This project provides a free online tool to check the JA3 TLS fingerprint of your HTTP scraper, mimicking what services like Cloudflare see. It highlights differences between browser and bot fingerprints, and offers a simple API for programmatic testing. The tool is interesting for its practical utility in web scraping and anti-bot evasion but is not technically novel.

Target audience: backend devs, data engineers
