HTTP is described as 'application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web' and is an app in the File Sharing category. There are nine alternatives to HTTP for a variety of platforms, including Mac, Windows, Linux, Self-Hosted solutions and Online / Web-based.

Other great apps like HTTP are ZeroNet (Free, Open Source), Freenet (Free, Open Source), Hypercore Protocol (Free, Open Source) and Solid (Free, Open Source).
