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.

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.

The Dungeon Crawler Carl Roleplaying Game is an officially licensed tabletop adaptation of Matt Dinniman's bestselling Dungeon Crawler Carl LitRPG novels, developed by Renegade Game Studios and launched via a BackerKit crowdfunding campaign in April 2026. The campaign became the most-followed TTRPG crowdfunding launch in history, pulling in over 27,000 backers and more than $6.6 million against an original $250,000 goal, putting it in the same company as Brandon Sanderson's Cosmere RPG and Avatar Legends among the biggest tabletop crowdfunders ever run.  The book series itself has an unusually indie-to-mainstream trajectory: Dinniman began posting it as a free web serial on Royal Road in 2020, and it grew organically into a multi-million-copy bestseller before Ace Books picked it up in 2024. Fulfillment for the RPG and its companion deck-building game, Dungeon Crawler Carl: Unstoppable, is expected in late 2026. Description Playing Dungeon Crawler Carl means playing a Crawler - a contestant, willing or otherwise - trapped in the World Dungeon, a lethal, alien-broadcast reality show where survival means keeping quadrillions of viewers across the galaxy entertained. The GM takes on the role of the System AI, the sardonic, rules-obsessed intelligence that narrates the dungeon, hands out achievements, and is never quite as fair as it claims to be.  Players can step directly into the shoes of characters from the novels - Carl, Donut, Katia, and others - or build an original Crawler from more than 30 species and a roster of gleefully absurd classes (Fire Mage Arcanist, Former Child Actor, Shotgun Messenger) that matches the source material's satirical, over-the-top tone. True to the books' obsession with loot, XP, and gamified progression, the ruleset leans hard into that same structure rather than smoothing it over for a more traditional fantasy feel.

HackMaster is a crunchy, old-school fantasy tabletop roleplaying game published by Kenzer & Company, created by Jolly R. Blackburn and David Kenzer. It began as a fictional game, a parody of Dungeons & Dragons played by the characters in Blackburn's comic strip Knights of the Dinner Table, and became a real product when the comic's fictional third edition turned into the published Fourth Edition in 2001. That edition won the 2002 Origins Award for Game of the Year 2001. HackMaster Fifth Edition followed in 2011, bringing a Player's Handbook and Gamemaster's Guide, and the line has since grown to more than forty add-ons and supplements. Kenzer and Company announced a 25th anniversary edition, HackMaster XXV, in March 2026 through a Kickstarter campaign. The Fifth Edition directly evolved from HackMaster Fourth Edition, which is a custom system derived from Advanced Dungeons & Dragons (AD&D). Description Players create characters from a race and a class, as in the older editions of Dungeons & Dragons, in a low-magic world that reads as strongly old-school. The default setting is the Kingdoms of Kalamar. The Game Master (GM) runs combat, exploration and the consequences of both, and the game's rules back up a harder, more simulationist style than the parody that started it. The game asks a table to accept a lot of detail. The rules are described as crunchy, with many optional combat moves and fighting styles and wound-by-wound healing that takes real time. It suits groups who enjoy knowing exactly how a fight works and don't mind reference tables, and it is a poor fit for anyone who wants a quick, rules-light evening.

Seasons 1-6: The Other Side of the Coin - Three friends find themselves as the last line of defense between the everyday world and the things that go bump in the night. Using Monster of the Week and other Powered by the Apocalypse games, the team works to save the Omniverse in this dimension hopping story. Season 7: The Clockwinders – Cadvini is in peril and it’s up to a group of Clockwinders in training to rediscover and repair the movement cores to save their world from the looming threat of destruction by fire, frost, and Fey. Using the Fate system in a world where there are eons of lost history, players unlock a world's worth of mysterious lore. Shows The Clockwinders The planet Cadvini is dying. Tidally locked, with one side a burning wasteland, and the other side a frozen forever-night, its people have managed to forge their lives in the temperate zone between. But the great old machines that keep the planet steady, called Movement Cores, have started to break down. The planet is beginning to spin, which could mean the ruin of all. Join Arkady ‘Kade’ Atwater, Einon Kerning, and Maxine Hollis as they venture across the wilds in order to find and fix the broken cores. They have Fey folk, aether-enhanced beasts, and all other manner of dangers to face… but this is their duty. They are The Clockwinders. Shadows in the Smoke Shadows in the Smoke tells the story of Hargrave House, a group of mysterious investigators in Victorian London who tackle the cases that Scotland Yard can’t or won’t. Amidst the monsters and murderers on the shadowy streets, an ancient power is growing in strength – a Queen in her own right, seeking vengeance against Victoria. Can the hunters discover her plot and save Queen and country, or will they succumb to their own darkness and become little more than the monsters they once hunted? Find out in Shadows in the Smoke, a Victorian gothic horror Actual Play utilizing The Between by Jason Cordova. Other Side of the Coin Our Monster of the Week campaign, wherein the characters are alternate-universe versions of the players themselves. Imagine that one minor thing could mean  the difference between our universe and another; something as simple as a  coin flip having the opposite result can lead to two drastically  different outcomes. We set the game in what is  essentially our world, albeit a version in which one small  decision changed the course of our hunters’ lives and set them on a  completely different path. While Monster of the Week will always  be the “home base” of our show to which our team will return,  our show is that it exists in a Powered By the  Apocalypse universe with many worlds… each of which conveniently seems  to be set within a different PBtA game!
