No mobile version, but I'm visiting from a tablet, should work at least if switch to "Desktop" in the browser manually. I don't care if I get horizontal scroll - not showing your visitors anything at all is an automatic "I'm out".

Second, when I browsed from an actual desktop, and clicked on links for files it was all slow as hell - specifically the part when you click on a file an expect it to just load, you instead get: 1) some layout switch which looks like page reload 2) then it says "loading..." for several seconds.

After looking at the source code, it appears to be React or similar frontend framework... Ugh. I don't know why people choose to use that stuff, just have a regular SSR which would work a hundred times faster and is more pleasant. And if you really want an SPA, don't use React, Vue or Svelte (and similar), it's horrible and always slow.

Finally, since this appears to be a YC company, it shouldn't matter what's it written in. In fact, I don't even know why Rust would be a good thing here when Go or even Rails/Django would work just fine - but again, it just reinforces the meme that if it's written in Rust, you'll surely hear about it.

Overall, the minimalism idea is welcomed, but it supposedly should appeal to people like myself and it doesn't for all the reasons I mentioned above.
