Hide your web link behind
a mini-coding challenge.

What's CodeCaptcha?

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.

How does it work?

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.

What languages does this support?

As of now we only support JavaScript. We may add more languages if there is demand.

The challenges are too easy

That is intentional. Soon we will let you choose difficulty level when creating a link.
