- Copyparty. https://github.com/9001/copyparty
- This is a valid Single File App (though not a Single File Web App)
- What's the difference? It's going through the web.
- A "web app" must run in a browser (https://en.wikipedia.org/wiki/Web_application).
- Two more that I've come across:
https://hyperclay.com/ and https://feather.wiki/
Thanks for mentioning TiddlyWiki btw.
- Another one I'd forgotten is Wiki On A Stick. It dates from 2006 or so, just after TiddlyWiki's first release
- Hyperclay involves a node js server. Feathre.wiki looks like a legit SFWA.
- Adminer
- I guess this would qualify as a Single File App (though maybe not a Single File Web App).
- This is my current personal project.
https://github.com/prettydiff/webserver
The backend is multiple files but the frontend is a single file SPA. It loads with state restoration and LCP in about 105ms.
- I'm surprised nobody mentioned slingcode: https://slingcode.net/
By far the coolest single file web app I've seen.
- I like simonw's: https://tools.simonwillison.net/
I vibecode a bunch of similar tools I use, inspired by Simon, and have them stashed where I can get to them.
- 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).
- Sure, but that stuff could easily be embedded into the file itself. I think the spirit is still there.
- If you count the scripts that could be embedded, any React app could be a single file. I don't think that matches the spirit, though.
- Why not, Dave? In fact, a number of my own vibe coded tools are single file React in HTML.
Disclaimer: I am not competent in React. It's what Claude generated by default and I ran with it so I could poke at the code and learn a little more about React.
- Agreed.
- Also feel free to add them to this list: https://github.com/calebmadrigal/Single-File-Web-Apps (just submit a PR)
