DarkFlare
DarkFlare Firewall Piercing (TCP over CDN)
...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 rather than exposing a raw TCP service directly. darkflare uses a client and server model, with the server side relaying traffic toward the intended destination. It is a specialized networking project, not a full VPN platform, and its value comes from combining TCP forwarding with an HTTPS-like transport layer.
