why are the repl host urls moving from the old style to these new stringed ones? is there a way to move back?
No you can not move back. You can view more info here Changes to Hosting on Replit!
If you don’t want a random
.replit.dev URL you’ll need to deploy your Repl to get a permanent customizable URL on
i wish they give us good looking urls back
Yes, you can get a good-looking URL by deploying. In my opinion,
replit.app is more good-looking than
repl.co. It’s also more similar to how Vercel and other similar hosting providers do it.
