i've been building apeirron for a while now. it's a force-directed knowledge graph covering 100+ topics — conspiracy theories, philosophy, ancient civilizations, power structures, consciousness, the cosmos — where every node is a long-form essay with real sources, and every connection between nodes has an explicit reason.
the whole thing is file-based. no database, no api, no cms. every node is a markdown file in a git repo. connections between nodes are defined as `[[wikilinks]]` inside the markdown. the graph, the site, and all relationships are generated at build time from those files.
contributing is just opening a pull request. i manually review every submission before it gets merged.
the interesting technical bit is the path system — guided sequences through the graph for people who don't know where to start. a path is just an ordered list of node references in a markdown file, nothing more.
