Lantern Box is the Lantern fork of sing-box, aka the Universal Proxy Platform. Lantern Box adds additional protocols, such as WATER, the proxyless protocol from the Outline SDK that uses things like TLS record fragmentation, TCP packet reordering, and DNS over HTTPS/TLS, etc to bypass DNS and SNI-based blocked, application layer Geneva, AmneziaWG, etc.
The goal of Lantern Box is simply to be as useful as possible to the censorship circumvention community and to sing-box in particular. Developers and infrastructure operators are encouraged to run Lantern Box servers and to distribute them to users, and we will continually contribute changes upstream whenever possible.
