CoovaChilli is described as 'Open-source software access controller for captive portal (UAM) and 802.1X access provisioning, based on the popular (but now defunct) ChilliSpot project, and ctively maintained by an original ChilliSpot contributor' and is an app in the network & admin category. There are more than 10 alternatives to CoovaChilli for a variety of platforms, including Linux, Windows, Mac, BSD and Android apps. The best CoovaChilli alternative is I2P, which is both free and Open Source. Other great apps like CoovaChilli are Hyphanet, GNUnet, Yggdrasil and i2pd (I2P Daemon).
The I2P network provides strong privacy protections for communication over the Internet. Many activities that would risk your privacy on the public Internet can be conducted anonymously inside I2P.
Hyphanet (former Freenet) is free software which lets you anonymously share files, browse and publish "freesites".
GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing.
A proof-of-concept scalable IPv6 meshnet, featuring end-to-end encryption, a unique spanning tree routing algorithm and aiming to implement novel backpressure routing metrics.
I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don't reveal their real IP addresses.

SMesh is a seamless wireless mesh network being developed by the Distributed System and Networks Lab at Johns Hopkins University.
Digitatas is a digital tree, a sapling to give technology to children of the Digital Generation. Under Open Hardware licensing by Open_Sailing and openet.org.
Ninux is an Italian wireless network community with the goal of creating and expanding a free, open and experimental computer network. It uses the OLSR (Optimized Link State Routing) Protocol, an IP routing protocol optimized for mobile ad hoc networks.
The vision of Project CCNx® is to develop, promote, and evaluate a new approach to a communication architecture called content-centric networking.
