as indicated by title above. most open source repo project uses this so its good indicator of how useful it is
Its different than an online IDE in that it generates a random string of letters at the end of its URL, similar to imgur.com
So you keep track of your repl's using URL's
like this one for instance https://repl.it/CLjU
It lets you have a version history tracker as well, very useful
You can also from what I recall use this to write code on your phone and then debug / clean up on PC

Repl.it is a fantastic app! It allows programming in over 30 different languages, and no download required! Complete with a classroom feature for teachers and students. Really a first class app!
Very useful for new developers or for using programs like NPM in your browser.
it's great for actually CREATING code, not just testing. On repl.it, you can actually create a website with HTML, which you can't do on something like jsFiddle.
