Show HN: A Local-only URL shortener

Category: library

Tags: url-shortener, compression, privacy

Score: 7.8/10 (Innovation: 8, Technical: 8, Documentation: 8, Utility: 7)

This project is a proof-of-concept URL shortener that encodes the target URL entirely within the URL fragment, ensuring the server never sees the encoded data for privacy. It achieves impressive compression via a combination of base32768 encoding, a prefix table, and a pre-seeded deflate dictionary, making short links fully self-contained and functional even when opened locally from disk.

Target audience: backend devs, security engineers, privacy-conscious developers
