smallweb-search
Wiby
A search engine devoted to hobbyist and early-web pages, complete with a 'surprise me' button that serves up a random old page. Search on the site itself, or via its simple JSON search endpoint, which this site can query directly. Good for serendipitous discovery of the classic web and for finding small hand-made pages on a topic.
