How can I cheaply save/preserve landing pages from old projects for my portfolio?

Are there any services that can host my landing pages so I don't have to pay hosting costs forever? I'm starting the process of another job hunt, and I've got 5-6 launched (and abandoned 😂) side projects that I currently link to in my resume. The process of listing them out made me go check how much I was actually paying just to keep these sites running, and tldr it was lowkey more than I expected. How do other people here handle this over the years? Is there any good way of saving my landing page at another link and just being able to include that link in my resume? I'm thinking like a WayBack Machine but just for my project's landing page—anyone know if something like this exists? Might be my next project if not. Thanks!!
