DarkFlare
DarkFlare Firewall Piercing (TCP over CDN)
DarkFlare is a tunneling utility that moves TCP traffic through HTTPS-looking requests routed across CDN-style infrastructure. It is designed for situations where direct TCP connections are restricted but outbound HTTPS traffic is still permitted. The project presents itself as a firewall-piercing tool, so it is best suited for authorized testing, private infrastructure access, or controlled research environments. Its approach focuses on making tunneled traffic resemble ordinary web traffic... -

Nipe
An engine to make Tor network your default gateway
Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently... -

Cloudflare Tunnel Client
Cloudflare Tunnel Client
Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins. This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible. Extensive documentation can be found in the Cloudflare Tunnel section of the Cloudflare Docs. All... -

Zapret
Advanced open source tool for bypassing DPI-based censorship
Zapret is an open source, cross-platform tool designed to help users bypass and evade Deep Packet Inspection (DPI)-based traffic blocking and censorship systems. Rather than acting as a traditional proxy or VPN, it works by manipulating network packets and traffic streams locally to confuse or disrupt DPI mechanisms used by ISPs and network filters, making it possible to access restricted websites and services without relaying traffic through third-party servers. Zapret implements multiple... -

File Tunnel
Tunnel TCP connections through a file
...This makes it useful in environments where direct TCP connectivity is blocked but a shared folder, FTP server, S3-compatible storage, Dropbox folder, RDP drive share, or similar file channel is available. The project provides portable executables for Windows, Linux, and macOS, which makes it practical for cross-platform testing. Its documentation includes examples for bypassing firewall limitations, tunneling through FTP, using remote internet access, and routing through remote desktop file shares. File-Tunnel is best understood as a specialized connectivity workaround for controlled environments where file access exists but normal network routing does not. -

DSVPN
A dead simple VPN
...No lousy documentation to read. No configuration file. No post-configuration. Run a single-line command on the server, a similar one on the client and you're done. No firewall and routing rules to manually mess with. Doesn't leak between reconnects if the network doesn't change. Blocks IPv6 on the client to prevent IPv6 leaks. Works on Linux (kernel >= 3.17), macOS and OpenBSD, as well as DragonFly BSD, FreeBSD and NetBSD in client and point-to-point modes. Adding support for other operating systems is trivial. -

FancySS
fancyss is a project for bypassing the Great Firewall (GFW)
Fancyss is a “scientific Internet access / bypassing censorship” toolkit targeted principally to Asus routers running AsusWRT or Merlin-based firmware. The project provides a plugin suite (with “software center” integration) so that home routers can run proxy or tunneling tools (e.g. V2Ray) to circumvent firewall or censorship (“GFW” in the Chinese context). Because it integrates into the router’s firmware environment, fancyss automates configuration, routing, and firewall rules to minimize... -

gooreplacer
A browser extension to modify HTTP requests
At first, Gooreplacer was created for redirecting Google Ajax/Api/Themes to other CDN to bypass Great Firewall since pages referring to those are slow as molasses. Most users prefer gooreplacer than other similar extensions(HTTPS Everywhere/Redirector) for ease of use. Why not give it a try? gooreplacer was originally born to solve the inability to access Google resources (Ajax, API, etc.) in China, which caused the page loading speed to be extremely slow. On this basis, the new version adds... -

Firefly
A proxy software to help circumventing the Great Firewall
Firefly is an agent used to access Great Firewall (GFW) blocked websites and applications. Under the default settings, Firefly only goes through VPN forwarding wall of IP traffic, IP wall straight. If you find a website or application you cannot access, Firefly flow mechanism can be built to distinguish between an error. In this case, you can choose to forward all traffic through the VPN, and then try again.
