Show HN: Stateless TikToken and Unix-Dictionary GitHub URL Shortener (selfdotsend.com)

A new project showcased on Hacker News, called Stateless TikToken, introduces a simple yet powerful URL shortener specifically designed for GitHub repositories. It efficiently processes both standard URLs and GitHub blob links, enabling automatic encoding and instant decoding with user-friendly shortcode input. This innovation employs TikToken's subword vocabulary to segment the URLs, leveraging a cached UNIX dictionary for optimal abbreviation. If a dictionary term is shorter than its corresponding string, it encodes the term as a compact symbol, preserving both its index and case in the encoded message. The significance of Stateless TikToken lies in its potential to streamline URL sharing, particularly within developer communities where GitHub repositories are frequently referenced. By minimizing URL length while retaining essential information, it enhances usability and accessibility for users. From a technical perspective, the project is entirely self-contained, allowing it to be hosted on any platform without a backend, thanks to its reliance on static files—index.html and words.txt. This makes it not only innovative but also practical for wide adoption in tech circles.
