Choose between private local vaults and online cloud worldbuilding.
World Anvil is a cloud-based suite for worldbuilding, but it stores all your notes on remote servers and locks advanced features behind monthly paywalls. Codex Cryptica provides a modern local-first alternative that is 100% free, private, and runs entirely in your browser with offline support.
Your campaign notes remain fully private, encrypted by the sandbox, and are never sent to remote databases.
Work on your campaign at the gaming table, on a plane, or in cabin retreats without requiring internet connection.
Your world wiki is saved as readable files on your computer. No vendor lock-in or database extraction limits.
