Overview 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. System Overview & Key Features The Vault System Obsidian organizes everything into a "vault", a folder of plain Markdown files stored locally on your machine. Your campaign notes are portable, readable in any text editor, and not tied to any server or subscription. There is no proprietary format and no account required to access your own files. Bidirectional Linking Obsidian's core feature is its wiki-style linking. Typing [[The Silver Throne Tavern]] in a session note creates a connection to that location's article, tracked in both directions. You can click any note and immediately see every other note that references it, from quest hooks to NPC backstories. Graph View Every link in your vault is visualized as an interactive network graph. Game Masters use it to see which NPCs are the most connected, which locations have no written articles yet, and where campaign threads intersect. It is a useful overview tool for large, complex vaults. Canvas Canvas is Obsidian's built-in infinite whiteboard. Game Masters use it to map out plot arcs, organize faction relationships, or plan dungeon layouts using a drag-and-drop interface that links back to notes in the vault. TTRPG Plugin Ecosystem Obsidian has no native TTRPG features, but community plugins cover most needs. Fantasy Statblocks renders monster and NPC stat blocks from multiple game systems inside your notes. Initiative Tracker handles combat order. Dice Roller allows rolls directly from the vault. The Leaflet plugin embeds interactive, pinnable maps into location articles. Each plugin is maintained independently, so quality and update frequency varies. Templater The Templater plugin allows you to define reusable document templates. For example NPC sheet with fields for Motivation, Secrets, and Stat Block, or a session template with sections for Recap, Key Beats, and Cliffhanger. New documents can be generated from any template in a single command, which significantly reduces repetitive formatting work. 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.

A local-first battlemap display tool for game masters. Cast a map with fog of war to a second "player" screen while you control everything from a private GM panel. Lodestar runs entirely in the browser with no build step and no dependencies. It runs entirely in your browser. No install, no account, nothing to download if you don't want to. You open it, load a map, click "Open player display," and drag that window over to your second screen. You control everything from your own DM panel, and your players only see what you choose to reveal. /images/general-media/1780915788_spLeMCfy.pngLodestar is completely free and open source, so you can use it, fork it, or tear it apart however you like. Maps — load high-resolution map images from local disk; pan and zoom freely. Player display — open a second window, drag it to another screen, and cast the map to your players. The player window can go fullscreen. Fog of war - Trace polygon areas and click them in reveal mode to show/hide on the player display. - Name polygon areas with a GM-only label. - Paint or erase fog with a round or square brush of adjustable size. - GM sees fog as an adjustable tint/opacity; players see solid black. Multi-floor — build multi-level locations; each floor has its own map, fog, tokens, and stairs. Navigate with the on-screen floor widget. Stairs — place GM-only staircase markers that link floors; they scale with the grid and zoom and are invisible to players. Tokens — drop, drag, label, color, and size them in grid cells; they snap to the grid and appear on both displays. Grid — toggle and adjust size, offset, color, opacity, and token snapping. Ping — Alt+click draws an animated marker on both displays. Measure — reports distance in grid cells and feet. Splash / blackout — show a splash image or a plain black screen on the player display instead of the map. Library — save full setups (image, grid, fog, tokens, floors, views) to a local IndexedDB library; export/import the whole library as JSON for backups or moving machines. When you save a map, it's stored locally in your own browser, not on a server somewhere. Nothing gets uploaded, so your maps stay on your machine. The catch is that the saved library is tied to the browser and device you saved it on, so it won't follow you to another computer or survive clearing your browser data. If you make maps you want to keep, use the Export button to save your whole library to a file. That file is your real backup, and you can import it on any device.
