Sometimes you want to share a link (like job postings, google forms, your project, a secret sub-page etc) to programmers only. This service let's you do that while also preventing abuse and spam.
It creates a unique link that you can share instead of your unprotected original link. Visitors are presented with a random coding problem to solve. The solution is almost always 1-3 lines and can be solved in minutes.
That is intentional. Soon we will let you choose difficulty level when creating a link.
