FrogFind: the search engine for vintage computers
The search functionality of FrogFind is basically a custom wrapper for DuckDuckGo search, converting the results to extremely basic HTML that old browsers can read. When clicking through to pages from search results, those pages are processed through a PHP port of Mozilla's Readability, which is what powers Firefox's reader mode. I then further strip down the results to be as basic HTML as possible.
FrogFind is a clever and incredibly useful search engine if you like to play around with old, outdated hardware with terrible browsers. It makes a lot of the web accessible, fast, and usable on my old Palm devices, for instance, but truly anything that at least has a browser should work just fine.
There are quite a few old and unmaintained platforms out there that cannot access the current web anymore, but tools like FrogFind address this problem in a very usable way. It's the creation of YouTuber ActionRetro, an excellent YouTube channel with tons of awesome vintage Mac (and other platforms) content.
