Deck n Roll

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.

Roll20 is the most widely used browser based virtual tabletop in the world, launched in 2012 following a successful Kickstarter campaign. Developed by Riley Miller, Nolan T. Jones, and Richard Zayas, it was designed to break down the barriers to tabletop gaming by requiring zero installation and offering a robust free to play tier. It remains the industry leader in total user base, hosting millions of games across nearly every imaginable tabletop system. Description Roll20 is the "everyman" of virtual tabletops, prioritizing accessibility and ease of use. Because it runs entirely in the cloud, players and Game Masters can start a session in seconds from any modern web browser. It features an integrated marketplace where users can purchase official rulebooks, adventures, and art packs that integrate directly into their campaigns. While it offers advanced features like dynamic lighting, its primary appeal is its massive community and the simplicity of its "pick up and play" nature. System Overview & Key Features No Installation Required Unlike many of its competitors, Roll20 requires no software downloads or server configuration. The Game Master simply creates a room on the website and shares a link. This makes it the ideal choice for groups with varying levels of technical expertise. Integrated Character Sheets Roll20 features thousands of community and official character sheets that handle the math for you. Clicking an attribute or a weapon on your sheet automatically sends the roll to the chat window, applying modifiers and calculating critical hits instantly. The Roll20 Marketplace The platform boasts the largest digital storefront in the industry. You can buy modules for D&D, Pathfinder, Call of Cthulhu, and more, which come pre loaded with maps, tokens, and journals, drastically reducing a Game Master's preparation time. Dynamic Lighting and Layering Subscribers gain access to a powerful lighting system that restricts what players can see based on their character's line of sight. The Game Master can easily manage different layers for maps, tokens, and hidden notes that only they can see. Built in Video and Voice Roll20 includes its own integrated WebRTC video and voice chat system, allowing groups to see and hear each other without needing to run third party software like Discord alongside their game window. Jumpgate Technology Introduced in 2024 and 2025, the "Jumpgate" update overhauled the core engine to provide a much smoother, high performance experience. It improved frame rates, reduced loading times, and modernized the interface to compete with newer, hardware accelerated platforms.
