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.

While Obsidian is an exceptional general-purpose tool, Codex Cryptica delivers a specialized workspace dedicated specifically to campaign running and writing, eliminating the need to debug complicated community plugin stacks before game night.
No account. No server database leaks. Just quick, private, local-first worldbuilding.
