Show HN: CodeNow, a Collaborative Coding App

I was doing a lot of Leetcode this winter, and got the idea of building something like it that used wasm in the browser rather than having to manage the complexity of executing remote code securely on a server.

Once I figured that out, I thought it would be neat to make it collaborative, like Coderpad — that part was a bit tougher, but it mostly works now, using WebRTC.

I'm not sure whether other people will think this is cool, but I had fun building it and learning more about wasm + WebRTC.
