One Realm is an AI-assisted campaign workspace and virtual tabletop built for groups that want to play tomorrow—not spend the week preparing. It turns adventures, source material, and campaign notes into an organized, playable world, helping GMs complete work that might otherwise take hours or days in a matter of minutes. Characters, locations, encounters, maps, relationships, and story events are automatically organized and connected. From there, the GM can prepare scenes, create artwork, manage characters, and run the game through the integrated virtual tabletop. Because everything shares the same campaign context, preparation flows directly into play without rebuilding the session across multiple tools.

OpenFray is a free, open-source combat console for Game Masters running Dungeons and Dragons 5e games. It is an initiative tracker that holds the whole encounter. It opens in a browser tab, needs nothing installed, and works without an account. Signing in is free, and it carries a Game Master's fights between devices. It keeps the parts of an encounter that are easiest to lose track of: initiative order, hit points, conditions and effects, concentration, and monster resources such as legendary actions, recharge abilities and spell slots. Effects have two ends, so OpenFray knows both who has advantage and who is granting it, and works that into the rolls. Every roll goes through one place and is logged with the dice behind it. A whole group can make one saving throw at once, with each creature's resistances and immunities already worked in. The table gets a screen of its own. A shared link lets the players follow the turn order and the game log on their phones, showing only what the Game Master chooses to give away. The built-in compendium ships the 2024 and 2014 rules, with opt-in libraries from Kobold Press and OpenFray's own books. Creatures and spells can be built by hand, pasted in as JSON, or taken from a D&D Beyond stat block with the free browser add-on. Compatible with Dungeons and Dragons 5.5e and 5e.

Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents.

Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

Skrat from the YouTube channel A Squirrel Plays is a rodent of many hats. YouTuber, Author, Streamer, Game Designer, Tester, and Reviewer! His YouTube time is spent trying to lift up and promote others while also working on his own projects and sharing his methods and way of thinking (or lack thereof) when it comes to both game design and storytelling. When he’s not playing the YouTube game or in a TTRPG session, he’s typing away and working on his next entry for Kesshonite Legends. A series of high-fantasy novels that can be read in any order that all take place in the same universe. If you have a TTRPG you’d like to show off, feel free to reach out to Skrat.

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.
