About wiki
Wiki.js is a modern, lightweight wiki application built on NodeJS and distributed as open source under the AGPL 3.0 licence, aimed at teams and organisations that want to publish and maintain their own documentation and knowledge base rather than renting a hosted one.
About utopia
Utopia is the world's first open source enterprise world model: a self hosted knowledge substrate with a bitemporal graph and an ontology at its base layer, built by DeepLethe for teams that need agent memory, governed knowledge, and a trustworthy decision core running on hardware they control.
