WebRTC P2P apps without centralized servers
1. Use local app server and mdns/bonjour/zeroconf to announce it for signalling
2. use webrtc for p2p udp communications

nicopace / Having your own mirror of f-droid repository.md
Created December 10, 2018 06:05

Having local mirrors of Free Software has been always a very useful thing. The most common repositories that are usually mirrored are ubuntu or Debian, but we can also mirror Android Free Software apps. We can use fdroid-dl and host it in a HTTP server like NGINX.

To do this:

  • pip install https://github.com/t4skforce/fdroid-dl.git
