When designing a simple prototype of contact page, I remembered that there is a possibility that the project will be hosted by the GitHub servers.
Example
But I also remembered that hosting with GitHub only supports Front End processing ie this contact form will not work since it should be done with a language that runs on the server side, PHP for example.
Doubt
Is it possible to run a contact form even though it is hosted in GitHub Pages?
If it is not possible, is there a zero cost alternative to resolve this problem?
