Obsidian Portal vs World Anvil

Obsidian Portal is a web-based campaign management site for tabletop role-playing groups. Its campaign wiki lets players organize game material in a shared campaign website, with a calendar, adventure log and character tracker to support campaign management. The service says it works with any game system and setting. The free Basic plan costs nothing and includes two campaigns, 2 MB per campaign and one map. Ascendant costs $5.99 a month and includes unlimited campaigns, 10 GB per Ascendant GM and 10 maps, as well as custom styling, player secrets, email notifications, selectable JavaScript capabilities, a dice roller and a campaign forum. Ascendant also offers public, friends-only or private campaigns. The service provides an API for developers creating tabletop tools or enhancing gaming experiences. Its privacy policy says member email addresses are not shared with third parties and users can choose public, limited or private access for their information. Support is available through a knowledge base, community forums and email, with a stated aim to follow up within 24 hours.

World Anvil is a browser-based set of tools for creating, organizing and storing settings for games, novels and comics. Its wiki supports linked articles, categories, tags and search across a world. Interactive maps connect locations to articles, while timelines track events across eras or parallel histories. Campaign tools provide a digital GM screen, statblocks, NPC creation, character sheets and session reports connected with campaign notes. Online novel-writing software works with the wiki, allowing setting details to be referenced and edited while drafting. Listed integrations include Discord, Google Analytics and Patreon links. Private material is visible only to the user and authorized collaborators, and autosaved work is backed up across multiple servers and in the cloud. World Anvil requires an internet connection; mobile use is through an optimized browser, with no mobile app. The Freeman plan allows two worlds, 42 articles and 100 MB storage.
