MOO Developer Resources
Source code, starter databases, manuals, and learning material for LambdaMOO and ToastStunt developers.
The original
LambdaMOO
LambdaMOO grew out of Pavel Curtis’s work at Xerox PARC in the early 1990s and became both a landmark social virtual world and the server that defined MOO’s object-oriented programming model. Its server and LambdaCore database became the foundation for generations of community-built worlds.
Development is active again. The new LambdaMOO 1.9.0 alpha unifies the long-lived 1.8.4 line with the Unicode/CodePoint branch and standardizes many extensions and fixes that operators previously obtained from separate patches, including WAIF, XML, Unicode, 64-bit integer, and bitwise support. It also incorporates more than two decades of accumulated bug fixes.

ToastStunt
ToastStunt is a modern C++ implementation in the LambdaMOO family. It is a fork of Stunt, which was itself forked from LambdaMOO, and continues that lineage with improved performance, modern networking and security features, richer debugging, and conveniences such as SQLite, PCRE, maps, booleans, WAIFs, and many additional built-in functions.
For a new MOO, ToastStunt paired with ToastCore offers a practical starting point while preserving the language and database-centered development style familiar to LambdaMOO programmers.
ToastStunt resources
- ToastStunt SourceThe server source, feature overview, and build instructions.
- ToastCoreAn updated LambdaCore-derived database for ToastStunt.
- Anatomy of a ToastStunt DBA tour of ToastCore’s important objects and systems.
