This is a rare requirement. Most people have a web browser already. A Gemini proxy allows you to read the web via your Gemini client.
This proxy only works for “sane” web pages, i.e. web pages that already look pretty much like they’re written in gemtext: headings, lists, no JavaScript, no cookies, and so on.
Duckling proxy is a Gemini proxy to access the Small Web. Connecting to it with your Gemini client means you can access many web pages directly with your favourite client.
This one you don’t have to install yourself, there’s a copy online with the author saying “better domain coming soon”.
All links and even images should work 🤞
