Tools & Platforms

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.

Saga20 Free Tools is a set of small utilities for D&D and TTRPGs, each built to clear one specific bottleneck at the table. Nothing asks for a login, nothing runs ads, and each one loads as its own page. The dice roller handles a d20 with advantage or disadvantage, applies the modifier, and rolls damage in the same click, with the full set from d4 to d100 and a typed input for things like 1d20 + 2d6. The Magic Item Price Calculator gives a fair gold value for any 5e item from its rarity and category, and shows the valid market range so a generous DM does not accidentally break the campaign economy. The Point Buy Calculator builds ability scores using point buy, the standard array, or rolled stats, with live modifiers under both the 2014 and 2024 rules. The rest follow the shape of a campaign. Before the first session, an agreement builder covers logistics, safety tools, and house rules, then exports to PDF, and a party connection generator ties the characters' backstories to each other. Mid-game there is a time manager for pacing and a wild magic surge table with 100 original effects. Afterwards the recap generator turns the night's highlights into cards worth sharing. There is also a shopkeeper generator, a magic item picker, and a party composition analyzer that says out loud whether anyone remembered to bring a healer. Best for any table wanting a quick tool or answer mid-session without making an account first.

Nat20.cloud is a free virtual tabletop for running and archiving your RPG campaigns. Play D&D 5e or Pathfinder 2e, build your own homebrew system, and run sessions online with combat tracker, battle maps, dice, notes, and rules reference, or use it solo as a GM screen.

RollCamp is a free, browser-based platform built only for D&D 5e (2024): character sheets that do the math, the SRD rules in an illustrated compendium, and a live table with maps, 3D dice and webcams, all in one place. There’s nothing to install, no paid plan, and no marketplace to buy into before you can play. Description Most virtual tabletops support every system, so the character sheet ends up being a form you fill in yourself. RollCamp does one game, and that’s the point: its 2024 rules engine knows what your class, species, background and feats give you, and recalculates armor class, hit points, saves, attacks and spell slots with every choice. Players build characters with a guided creator, Game Masters prepare campaigns and run sessions, and everyone meets at the same table in the browser. The table needs a desktop browser; sheets and the compendium work on phones too.

D-Roller is a free online dice roller built around a real rigid-body physics engine rather than a random number generator. Every throw is simulated — sequential impulses at a fixed 360Hz, full collision between dice, friction and restitution — and the result is read off the geometry of whichever face ends up pointing at the ceiling. Nothing is drawn in advance and nothing can produce a number without the dice actually being thrown. It carries the full polyhedral set — D4, D6, D8, D10, D12 and D20 — and up to twenty dice on the table at once in any mix, so an attack and its damage are one throw rather than two. It also reads a roll the way a table does. Two D20 are shown side by side and never added, because two twenties are advantage or disadvantage and no such total exists; a D20 thrown beside damage dice keeps the attack as the headline and the damage underneath; and a D10 that lands on 0 counts as ten, the way the printing on a real one means. Five die finishes, seven table surfaces, impact sound, and a stage the player can relight. No account, no download, no advertising in the roller. It runs in the browser, on a phone as well as a desktop. Links d-roller.com - Official website

Rollful is a hosted dice-rolling API. It rolls dice over HTTP: a request carries a formula, and Rollful parses it, rolls each die through a cryptographically secure generator, and returns every die it rolled rather than only the total. It is not tied to any game system. It knows what 4d6kh3 means and nothing about what the caller uses it for, so it suits a virtual tabletop, a character sheet, a Discord bot, or anything else that needs a roll it can show the working for. The formula grammar covers flat modifiers, advantage and disadvantage, keeping the highest or lowest dice, exploding and penetrating dice, multipliers, several terms in one roll, and tags. The response lists every die with a flag saying which ones counted, so an interface can show the die a keep rule dropped instead of hiding it. A GET request handles a plain formula. POST adds bonuses and tags, and a batch endpoint takes up to 20 rolls in one request. Every response and error has the same documented shape, described by an OpenAPI 3.1 document. There is no account and no API key. Usage is rate limited rather than metered. The homepage carries a form for rolling dice straight from the browser. Rollful is powered by the OpenDice npm package, which is free to use directly in any JavaScript or TypeScript project.

Statblock Maker Pro is a free, always-online 5e D&D toolset with no account, no login, and nothing saved to a server. It covers the full prep-to-table pipeline: a creature/statblock maker and item maker (2014 and 2024 rules), a spell creator, a character creator, and a token stamp for VTT art. On the table side, the encounter maker and initiative tracker run combat live, with a combat difficulty calculator that shows 2014 and 2024 difficulty math side by side and a Monte Carlo battle forecast to sanity-check a fight before you run it.

TAS is a multi tool application for Mongoose Traveller 2E, that provides several options for players, GMs, and solo players. The Travellers app is designed to allow for guided or random character creation, rolling your own dice or letting the app roll them.  You can also track multiple characters across sub tabs, update their stats, add items and then save them, and share them with direct sharing links. They Shipyard app allows you to open and modify several classic Traveller ships, or design your own from scratch.  Save and export your ships as desired. The NPC Vault is a stripped down automated NPC creator that allows GMs to quickly create NPCs across different career archetypes, tech levels and experience levels, as well as mix archetypes.  Edit, save and export the NPCs as needed. /images/general-media/1786113792_7ncg53gt.webp   The Voidmapper tool shows you the 8x10 hex map. It lets you automatically generate a single world hex at random, a single sub sector or several sub sectors, or you can import the cannon sectors from travellermap.com.  Once you have imported your sectors, you can import ships from the Shipyard and add Characters from Travellers to that ship.  Each sector has the full trade and passenger information based on the system rules.  You can give your ship credits, track your in game trades, and passengers if your table wants to automate finding trade goods, and passengers and tracking what is on your ship and how much you spend and make.  You can also use this as a mini game to travel a system trading and trying to earn a profit.  Lastly each system has a savable notes section, random tables for encounters and details about the secondary worlds. /images/general-media/1786113857_yrNMc5pe.webp Lastly check the Ops Menu for the readme for each section for more detailed information and the up to date change log.

DiceCalc is a TTRPG dice managmeent system for players and GMs. Here's what it does: Roll all of a character's dice simultaneously — see every attack, save, skill, and modifier roll all at once via the Roll All mode with character tabs. Still reroll per macro — long-press any single roll to edit or reroll just that macro without rerolling the rest, even in Roll All mode. In-depth macro inspection — Roll Macro mode focuses on macro options, allowing players to inspect rolls, rename, edit, and sort the macro list. Sort order here is also preserved in Roll All mode. Cryptographically secure random number generation — higher unpredictability, more randomer. Sortable character tabs with up to 100 macros each — whether you're running or playing a campaign, organize by character, encounter, monster, game system, or any other way you like. Every major TTRPG dice mechanic in one app — keep high/low, target numbers (successes), botches, exploding dice, crit detection, multi-roll comma separation for staged (verification) rolls, and yes... push dice! Constraint validation with red-highlighted error feedback — pathological expressions are caught before they run, no infinite loops or broken math. Persistent 300-roll history with timestamps — every roll logged with full roll breakdown and no truncation. Tap-and-hold context menus throughout — edit, duplicate, delete, rename, reroll wherever it makes sense. Localized in 7 languages — English, Spanish, Portuguese, German, French, Italian, Polish, with complete in-app manuals for each. 14-page in-app user manual — every feature documented with examples, no need to leave the app. Supports Android 8.0 and above — runs on devices going back a decade. Custom QWERTY keyboard for macro names — with locale-specific diacritics via long-press. Independent horizontal scroll per output row — nerd out inspecting long expressions, results, and roll details without truncation. Also... I'm giving it away for free till 09/31/2026 11:59:59 (JST).
