Sure, but that stuff could easily be embedded into the file itself. I think the spirit is still there.

Some of these are indeed Single File Web Apps (though a few of them contain links to external js and such, which would disqualify those from being a SFWA).

I like simonw&#x27;s: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;</a>I vibecode a bunch of similar tools I use, inspired by Simon, and have them stashed where I can get to them.

What&#x27;s the difference? It&#x27;s going through the web.

This is a valid Single File App (though not a Single File Web App)

Copyparty.

I guess this would qualify as a Single File App (though maybe not a Single File Web App).

This is my current personal project.<a href="https:&#x2F;&#x2F;github.com&#x2F;prettydiff&#x2F;webserver" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;prettydiff&#x2F;webserver</a>The backend is multiple files but the frontend is a single file SPA. It loads with state restoration and LCP in about 105ms.

Also feel free to add them to this list: <a href="https:&#x2F;&#x2F;github.com&#x2F;calebmadrigal&#x2F;Single-File-Web-Apps" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;calebmadrigal&#x2F;Single-File-Web-Apps</a> (just submit a PR)

Thank you. That&#x27;s one of the few that I found.

I&#x27;m trying to get a Wikipedia page for Single File Web Apps approved (https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Draft:Single_File_Web_Apps), and I&#x27;m trying to find good examples of Single File Web Apps (web apps that are just a single HTML file). Please comment if you know of any.
