A local-first comparison for RPG campaign managers and worldbuilders.
Both Obsidian and Codex Cryptica offer powerful local-first markdown linking, but they target different goals. Obsidian is a general-purpose note-taking application requiring multiple community plugins to manage campaigns, whereas Codex Cryptica is built from the ground up for TTRPG mechanics, maps, timelines, and relationships.
Built-in campaign templates for characters, events, factions, and locations, rather than generic blank pages.
Native temporal maps supporting custom calendars and historical eras without relying on plugin code.
Immediate context-aware RPG generation with no external API configuration needed.
