Moor is a Rust-coded server that aims to run the original LambdaMOO core and provide a more modern foundation for future development. LambdaMOO is a long-standing MUD (multi-user, text-based virtual world) that stands out for its programmable environment, allowing users to develop RPGs within it. The goal of Moor is to maintain compatibility with LambdaMOO 1.8.x series while improving upon it. The server is feature complete and compatible with LambdaMOO 1.8.1, supporting different types of connections, monitoring, and metrics. The author encourages users to try it out, report bugs, and contribute to its development.
