OpenFray

A portable, offline-first DM and worldbuilding tool. Build worlds, run sessions, share with others and play together, all in one app. License: CC BY-NC 4.0 · Free to use Everything core works **without an account**. You only need one to play online, publish to the marketplace, or download other users' content. /images/general-media/1791564204_7DEx9r3t.webp Worldbuilding - Era Timeline: Split your world's history into eras on a timeline bar and move between them. Each era keeps its own map, pins, nested location maps and day-by-day timeline pins linked to cards and sessions. You can show the same city before the war and after it. - Templates & Packages: Every world is built on a template (D&D 5e is built in) and pulls content from packages. A package is a bundle of cards you can install into any world, link to other packages, or share on the marketplace. Custom templates are coming. - Codex: Schema-driven cards for NPCs, monsters, spells, items, locations and more. Every reference is a tappable link. Pin cards to the top, preview any card with a long press, and search by name, tag, category or text. - World Map: Pins, grid and scale, drawing, fog of war, and nested maps you can walk into (districts, dungeons, taverns). - Mind Map: An infinite canvas with linked nodes, workspaces, freehand drawing and undo/redo. /images/general-media/1791564252_TB7zwrCp.webp Running the Session - Second Screen: Give the table its own view. Pop out a window onto a second monitor, cast to a TV or projector, or project into every connected player's app. You choose how battle maps, images, cards and PDFs go out. Fog of war and hidden tokens stay hidden. - Battle Map: The session screen *is* the map, with the encounter panel and event log on top. It has layers, fog of war, AoE templates, 5e diagonal rules, creature-sized tokens, shapes and text, a DM-only layer, hidden tokens, movement trails for the round, and two maps joined into one. - Combat Tracker: Initiative, HP (with hit-dice rolls), conditions, turn order and an event log. - 3D Dice: Dice roll across the screen with named styles. Skills and saving throws roll from the character sheet with one tap. - Soundpad: Layered ambience with gapless loops, fades and ready-made soundpacks. - PDF Library: PDFs kept inside the world, opened in tabs and shareable with players. /images/general-media/1791564292_BnuuXJTS.webp Characters - Full 5e rules: Species, class, subclass, background and feats fold into one sheet. Each sense, resistance, proficiency, trait and always-prepared spell shows where it came from. Also covers multiclassing, spell slots, class resources (Rage, Bardic Inspiration, sorcery points…), weapon mastery, and short and long rests. - Character Builder: Pick species, class, subclass, background, ability scores, skills, starting equipment and feats from the SRD and any installed pack. - Level-Up: HP, proficiency bonus and hit dice update automatically. ASIs, feats, subclass and spell picks wait as pending choices. /images/general-media/1791564330_JBRRDNZ4.webp Playing Online - Online worlds: Put a world, package or character online and it stays the same on every device you sign in on. Players see the pictures even when the DM is offline. - Players: Join with an invite code, claim a character, move your own token on your turn, and send dice rolls to the DM's log. Shared cards update when the DM edits them. - .dmtz files: Export a world, package or character to one file and import it anywhere. No account or network needed. Content - SRD 5.2.1: Built in and works offline. - 19 one-tap packs: Tome of Beasts (1–3, 2023), Creature Codex, Monstrous Menagerie, Black Flag SRD, Deep Magic, Tome of Heroes, Vault of Magic, Tal'Dorei and more. - Ready-made worlds: 99 Devils of Uzrah's Palace (Shadowdark), Army of the Damned, The Cold Bounty, and soon our own campaign Aegis Act . - Marketplace: Publish worlds, templates, packages and characters as versioned snapshots with content previews. - Social: Profiles, follows, an activity feed, direct and group chats, and game listings with applications.

Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents. Every character, faction, location, and event you create becomes a linked entity, so your world stays connected and explorable as it grows. Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

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.

Do you love Eberron, or maybe you've just recently heard of the setting with the release of Eberron: Forge of Artificer? What if I told you there's a whole community of players and DMs that have been around for half a decade, running multiple adventures and connecting unique characters and yes even making memes just a link away? That's right! Eberron: Legends of the 5th Dawn is a server in discord where we run D&D games! Not only seamlessly combining 5e and OneDnD content, but adding popular Eberron 3rd party content such as Exploring Eberron and other Keith Baker products to our player options. All while DMs bounce ideas and look into popular 3rd party sources like Duran's Guide to the Blood of Vol and the Giant's Guide to Xen'drik for even more stories to unfold! We have Sharn as our main hub, so even when you're not engaging into quests you can roleplay with a vast community and bring your own stories into the mix. With special encounters avaliable so you can fight crime in the streets of Callestan or help patrol King's Forest against the nefarious Jungle Boys!

Including the implementation of holiday events providing special challenges and opportunities. Discord server - Eberron: Legends of the 5th Dawn

Avatar Legends: The Roleplaying Game is an officially licensed tabletop roleplaying game set in the world of Avatar: The Last Airbender and The Legend of Korra, designed by a team led by Brendan Conway (with James Mendez Hodes, Yeonsoo Julian Kim, Sharang Biswas, Daniel Kwan, and Sen-Foong Lim) and published by Magpie Games. It launched via a Kickstarter campaign that raised over $10 million - one of the highest-funded TTRPG crowdfunders ever run - with a digital release in October 2022 and the physical core book following in January 2023. The system is built on the Powered by the Apocalypse engine, the same design lineage that traces back to Apocalypse World, adapted here around the show's elemental combat and character-driven melodrama. Description Players take on benders, martial artists, and technologically-minded specialists living somewhere across five playable eras of the setting - Kyoshi's age, Roku's era, the Hundred Year War, Aang's timeline, or Korra's modernized world - navigating a world of four elemental nations where manipulating earth, water, fire, or air is a normal, visible part of daily life.  Sessions mix character drama with fast, narratively-driven combat: a Game Master frames scenes and plays the setting's antagonists, who are written to have their own motivations rather than serving as disposable obstacles. The game leans hard on internal conflict as much as external - characters are built around competing values as much as combat skill, and are expected to be pulled off-balance by the people and ideals they care about, not just by getting hit.

High Guard Rules brings Classic Traveller's Book 5: High Guard starship construction and combat rules to the web. Ship Designer walks you through building a warship from the keel up — hull, jump and maneuver drives, power plant, computer, weapons, and screens — following the Book 5 construction sequence, with every calculation (tonnage, energy points, agility, cost) handled for you automatically. Combat Arena lets you pit your designed ships against another player, or fly solo against an AI opponent — resolving the full Book 5 ship-to-ship combat sequence round by round: Battle Formation, Initiative, Range, Pre-Combat Decisions (break-off, emergency agility, surrender), Combat, Damage, Breakthrough Combat, Pursuit, and a Terminal step for boarding, repair, and crew transfer. Ship Library keeps your saved designs on hand, and Meeting Room is where you find another player and start a battle. Whether you're building a fleet, sparring with the AI, or working through a firefight against another captain, this site handles the math so you can focus on the tactics.
