I just started using Scratch, and am being taught the basics of it in school. I used a YouTube tutorial to create a simple platformer, and made my own sprites and backgrounds and levels and stuff for that platformer in MS paint. Is there any way to type a link into Chrome on any computer and be able to play it there? Do I need to make/pay for a website/url to do so? I'd like it to be kind of like a .io game, where you can just type (name).io into Chrome and the game will come up, or for now, any url kind of thing. Any help is appreciated, thank you.

If a project is shared anyone can run it on Scratch and that's your best bet - they don't need an account to do so.

You can inbed shared Scratch projects onto other websites if you want.
