Obsidian is a free, locally-stored Markdown note-taking application that the TTRPG community has widely adopted as a campaign wiki, session planner, and lore database. Originally designed as a personal knowledge management tool, it stores everything as plain text files on your own machine with no subscription required. Description Unlike purpose-built platforms such as World Anvil, Obsidian was not designed with TTRPGs in mind, which means it arrives without templates, stat block support, or any TTRPG-specific structure out of the box. GMs who want those features need to install and configure community plugins themselves, which carries a steeper setup cost than dedicated alternatives. For those comfortable with that process, however, the result is a highly customizable system with no ongoing fees and no vendor lock-in. A thriving plugin ecosystem has filled most of the gaps, and the tool has become a genuine alternative to subscription-based worldbuilding platforms for technically comfortable Game Masters. The plugin ecosystem extends well beyond what is listed here, with community tools covering everything from database-style note querying and cross-device sync to interactive maps and combat automation. A full directory is available at community plugins.

Trails Weaver is a visual worldbuilding app for game masters, worldbuilders and writers. Every character, location, faction and item is a page with rich text, images, custom properties and a relations table, and any page can also be dropped onto a board. There are four board types: - an infinite free board where element cards nest inside other element cards. - map boards with pins, regions and roads that reveal more detail as you zoom in. - hierarchy boards for family trees and chains of command. - relationship graph that assembles itself from the relations recorded on each page Anything marked secret stays hidden when a world is shared through a read-only public link. The free plan covers one world, unlimited free-boards and up to 25 world elements. Pro removes every limit.
