- [tor](https://www.torproject.org/about/overview.html.en) - The Tor network is a group of volunteer-operated servers that allows people to improve their privacy and security on the Internet. Tor's users employ this network by connecting through a series of virtual tunnels rather than making a direct connection
- [i2p](https://github.com/i2p/i2p.i2p) - I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.
- [vuvuzela](https://github.com/vuvuzela/vuvuzela) - Vuvuzela is a messaging system that protects the privacy of message contents and message metadata. Users communicating through Vuvuzela do not reveal who they are talking to, even in the presence of powerful nation-state adversaries.
- [whonix](https://github.com/Whonix/Whonix) - Whonix is an operating system focused on anonymity, privacy and security. It's based on the Tor anonymity network, Debian GNU/Linux and security by isolation. DNS leaks are impossible, and not even malware with root privileges can find out the user's real IP.
- [lantern](https://github.com/getlantern/lantern) - Lantern is a free desktop application that delivers fast, reliable and secure access to the open Internet for users in censored regions
- [MTProxy](https://github.com/TelegramMessenger/MTProxy) - Proxy server which helps telegram users who are inside censored areas still be able to connect to telegram
- [telex](https://github.com/ewust/telex) - involves placing anticensorship technology into the Internet's core network infrastructure, through cooperation from large ISPs.
- [uproxy](https://github.com/uProxy) - uProxy is a browser extension that lets friends route their connection to their Internet through each other's computers. It can help people with restricted or insecure access to the Internet get to the content they care about safely.
- [WireGuard](https://www.wireguard.com/) - WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPSec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN.
- [marionette](https://github.com/kpdyer/marionette/) - Marionette is a programmable client-server proxy that enables the user to control network traffic features with a lightweight domain-specific language.
- [iodine](https://github.com/yarrick/iodine) - This is a piece of software that lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed.
- [obfuscated-openssh](https://github.com/brl/obfuscated-openssh) - Handshake obfuscation strengthens the initial SSH handshake against systems that identify or classify various network protocols by examining data in transit for static signatures.
- [infranet](http://sourceforge.net/projects/infranet/) - Infranet is a system that attempts to circumvent web censorship by allowing clients to surreptitiously request sensitive content via cooperating Web servers distributed across the global Internet.
- [code-talker-tunnel](https://crysp.uwaterloo.ca/software/CodeTalkerTunnel.html) - Code Talker Tunnel (previously called SkypeMorph) is a protocol camouflaging tool, designed to reshape traffic output of any censorship circumvention tool to look like Skype video calls
- [stegotorus](https://sri-csl.github.io/stegotorus/) - StegoTorus, a tool that comprehensively disguises Tor from protocol analysis. To foil analysis of packet contents, Tor’s traffic is steganographed to resemble an innocuous cover protocol, such as HTTP.
- [go-packetflagon](https://github.com/BrassHornCommunications/go-packetflagon/) - A local HTTP application that serves customised Proxy Auto Configuration files for your browser to help bypass Internet censorship.
- [AKASHA](https://akasha.world/) - next-generation social media network immune to censorship by design. It is built on top of Ethereum using Smart Contracts and IPFS
- [Real Steganography with TrueCrypt](http://keyj.emphy.de/real-steganography-with-truecrypt/) (applies to VeraCrypt as well) - hiding containers inside MP4 video files.
- [PixelKnot](https://github.com/guardianproject/PixelKnot) - image steganography for Android.
- [cachebrowser](https://github.com/CacheBrowser/cachebrowser) - CacheBrowser is a system designed to help Internet users bypass Internet censorship. The core idea ofCacheBrowser is to grab censored content cached byContent Delivery Networks such asAkamai andCloudFlare directly from their CDN edge servers, therefore, foiling censors' DNS interference.
