Wikipedia Reader for System 6 and up has been released. It allows you to
retrieve Wikipedia articles via their API and read them on your vintage
Macintosh.
Or in the words of the author:
> Due to Wikipedia no longer serving its API over plaintext HTTP, a plaintext-to-TLS proxy is required to forward requests. Currently this defaults to using a free Cloudflare worker that I've setup, but the settings dialog in the application allows changing this to a private proxy if so desired (or perhaps some actual host on
wikipedia.org if they ever support plaintext again).
> No translation or conversion is done server-side. Wikipedia Reader accesses the raw Wikitext markup of an article through the Wikipedia API, parses the markup, converts UTF-8 to MacRoman, and displays the text. Basic formatting such as bold, italic, underline, and header sizes are supported, and clicking on a hyperlink to another article will jump to that article.
