✦ This isn't a glossary anymore
A curated knowledge graph with editorial governance
A typical glossary gives you terms, definitions, and a search box. This goes further.
Terms are connected by reviewed, typed relationships, making it possible to follow how ideas relate across the entire corpus. Every connection is sourced, reviewed, and tracked, while the system continuously checks for missing links, dead references, and gaps in coverage.
The result is less a glossary and more a curated knowledge graph — designed not just to define concepts, but to show how they connect.
Glossary
A developer glossary, written to teach — built to be cited.
1.5k terms across 33 categories — definitions, examples, common mistakes and fixes. Authored under one editorial standard. Cross-linked, searchable, and openly crawled by AI agents.
