I made a site https://snack.game where people can upload and share multiplayer games.
It uses webtransport instead of websockets for the networking transport so the games feel a lot better than normal web based multiplayer games. I'm surprised more people aren't using webtransport given it's supported now by all major browsers.
How has WebTransport treated you in practice? I just shipped a little live map where everyone sees new reports pop in as they happen — I went with Supabase's realtime channels because I didn't trust myself to run my own socket layer, but I keep wondering what I'd gain by going lower level. Did you hit browser-support pain?
No browser support issues, the pain I run into is people running on vpns or their company's internet which block udp and by extension webtransport.
