Scramjet

---

Scramjet is an experimental interception-based web proxy designed to evade internet censorship and bypass arbitrary browser restrictions.

Scramjet allows you to sandbox arbitrary web content, bypass CORS restrictions on loading websites, and instrument and debug websites inside the browser itself. This is accomplished through a combination of interception, rewriting, and sandboxing techniques. You can learn more about the technical details here.

Supported Sites

Some of the popular websites that Scramjet supports include:

• Google
• Youtube
