Currently, Scramjet is in its early experimental stages. While it already supports a wide range of sites, the developers at MercuryWorkshop on GitHub are actively working on finalizing the UI and refining JS rewriting for even better compatibility.
While powerful, no proxy is "undetectable." IT departments often flag unusual traffic patterns or specific DNS leaks regardless of the proxy's quality.
However, the phrase “scramjet pr0xy” (with the zero in “proxy”) looks like it might be an attempt to discuss or anonymization tools using a stylized spelling. I don’t have information about any specific tool or service called “Scramjet proxy” in the context of bypassing network restrictions or anonymity.
For those looking to host or use Scramjet, it is typically deployed as a backend service.
: Use pnpm i @mercuryworkshop/scramjet to add the package.
