I hope you have good measures to stop spam and to stop people abusing your run features. Or even just to stop things like infinite loops in this code sample (if the syntax error is fixed) https://harigami.net/cd?hsh=0b7c2f43-bf85-4efe-bedb-f6b60c8f... (I didn't submit that sample btw)

During candidate selection, we were desperately looking for something like this. Code sharing is available at many places. But running the code is nice feature. But as @jarofgreen pointed out, how will you stop abuse?

# What is this?

This is a web service for sharing soruce code. The most important feature is that this doesn't require signing up for submiting source code. Users can share their source code without any account. It uses unique URL for sharing source code.

# Why did I build this?

For sharing source code, we can use GitHub or Gist, GitLab and so on. These services require us to sign in before sharing source code. However I sometimes want to share small source code like snippet with syntax highlight on SNS. Almost of popular SNSs don't have syntax highlight or code sharing feature easy to see. This is why I built this service.

# What is it different?

This doesn't require users to sign in.We don't need to create account for sharing source code. This is very simple. Just copy and pasete source code on textarea and click submit button. Then you can share source code by URL.

Looks nice. I like the idea. I wish the UI could be improved more. For example, I see all the languages on left, they could be sorted by the number of codes in a descending order. There is just too much white color. I am color blind, maybe you could have used Bootstrap or Material to get started. I see "No title" everywhere, do we need to see "No title" or maybe not show anything?

I assume the back-end is very straightforward (basic abstraction over S3), so please focus on the front-end.

AKA pastebin?
