An online hub your players log into, or a private campaign brain that lives in your browser.
Chronica is a browser-based campaign manager built around the whole party: every player has an account, and the GM shares quests, inventories, shops, maps and calendars with them in one online hub.
Codex Cryptica starts from the other end. It is the GM's lore graph: characters, factions, places and events, all connected, stored locally in your browser and usable offline. Players join live sessions by link when you want them to, without accounts.
See how NPCs, factions, places and events connect in one interactive graph, built from the entities you write.
Track events on custom calendars and pin locations to maps, so campaign history and geography stay tied to your lore.
Your vault lives in your browser and works without a connection. Sync it to a folder on your computer or back it up when you choose.

You want a shared online home for the whole party.
You want a private, connected record of your world.
These tools solve different problems. Chronica is the stronger fit when you want your players inside the tool between sessions, tracking their own inventories, quests and kingdom alongside you.
Codex Cryptica is the stronger fit when the campaign mostly lives in the GM's head and notes, and you want that lore connected, private, offline and in files you own.
No account required. No subscription. All your campaign notes stay on your own device.
