Nicholas Jitkoff, vice president of design for Dropbox, developed the Itty bitty site technology, which allows you to create web pages that are stored inside their own URL in an encoded form.
Development allows you to create single-page mini-sites. On the page, you can place text, ASCII characters and emoji in any combination. The peculiarity of the technology is that all the content is contained in the hyperlink, and hosting on the server is not required. The content of the page is encoded using the LZMA compression algorithm in a string of characters, which is appended at the end of the URL. In fact, the link is an archived site.
The developer claims that Itty bitty site provides a high degree of privacy. The content of the page is not stored on the server, and therefore no access even to the administrator. Moreover, most browsers will handle the link locally.
The maximum size of the URL depends on the capabilities of the service. Twitter or Slack can process up to 4,000 bytes, and the version of Chrome for Mac will cope with 10,000. It is possible to convert the link into a QR-code, provided its size does not exceed 2,610 bytes.
Jitkoff posted the source code for development on GitHub. The author offers several options for the practical application of Itty bitty site: to overcome the limitation of the number of characters in tweets, for placement on pages of ASCII graphics, small poems and even for application creation.
