Also in this update: the collapsed Properties panel shows how many properties are inside, elements without a picture show their type icon instead of a dark tile, and several fixes around deleting nested elements.

Dice became a real part of a world. Roll tables with weights or classic d100 ranges, rich text outcomes, and a library shared across the whole world. Roll buttons sit on Free boards and tumble 3D dice with a per die breakdown. Inline dice chips live in any page and work in the read-only share view, so players can roll while your prep stays put. Saving also got faster: the app now sends only what changed. Full notes: https://app.trailsweaver.com/updates/roll-tables-dice-and-faster-saves External link

Overview

Trails Weaver is a visual worldbuilding app for game masters, worldbuilders and writers. Every character, location, faction and item is a page with rich text, images, custom properties and a relations table, and any page can also be dropped onto a board. There are four board types:
  • an infinite free board where element cards nest inside other element cards.
  • map boards with pins, regions and roads that reveal more detail as you zoom in.
  • hierarchy boards for family trees and chains of command.
  • relationship graph that assembles itself from the relations recorded on each page
Anything marked secret stays hidden when a world is shared through a read-only public link. The free plan covers one world, unlimited free-boards and up to 25 world elements. Pro removes every limit.

Key features

Cards inside cards

Element cards nest inside other element cards on an infinite board. A city holds its districts, a district holds the people who run it.

Notes that think they're pages

Sticky notes on a board carry headings, tables and to-do lists, and connect to each other when the plot does.

Share without spoilers

Send a world through a read-only link. Anything marked secret stays hidden from everyone you share it with.

A graph that draws itself

Record a relation on a page and it shows up in the relationship graph. Filter to one house or faction and the rest falls away.

More than family trees

Map bloodlines, noble houses, guild ranks, pantheons and chains of command. Every tree lays itself out as you add to it.

Maps that open as you zoom

Upload a map, draw roads and regions, drop pins. A country reveals its cities, a city reveals its districts.

donjon is a legendary, minimalist suite of web-based procedural generators that has served as the "Swiss Army Knife" for Game Masters since its first dungeon generator went live in 1999. Created and maintained by a developer known as drow, the site eschews modern flashy graphics and subscriptions in favor of raw utility and speed. In late 2025 and 2026, the site saw a significant "5.5 Refactor," adding full support for the 2024 D&D Core Rules, including new treasure tables, encounter calculators, and Bastion event generators. Description donjon is the ultimate tool for the "Zero-Prep" GM. It is a collection of text and image-based algorithms that can generate everything from a single NPC to an entire star system in less than a second. While newer tools focus on 3D visuals, donjon remains a favorite because it is incredibly lightweight; it loads instantly on any device and provides high-density information without any clutter. It is the "source code" of many GMs' campaigns, providing the mechanical backbone for loot, encounters, and world-building data. System Overview & Key Features Random Dungeon Generator The crown jewel of the site. It creates fully mapped-out dungeons with "old-school" aesthetics. You can specify the level, layout, and "dungeon motif" (like Sunken Temple or Abyssal Rift), and it will populate the map with traps, secret doors, wandering monsters, and room descriptions automatically. D&D 5.5 / 2024 Core Support New for 2026, the site features a dedicated "5.5" section. This includes an updated Encounter Size Calculator that accounts for the 2024 power scaling, as well as a Magic Shop Generator that utilizes the new pricing and item rarity structures introduced in the latest D&D revision. Fractal World Generator This tool uses a recursive algorithm to generate entire world maps with realistic coastlines, islands, and tectonic-like features. GMs can adjust the "Ice Limit," "Water Percentage," and "Scale" to create a unique continent or a planet-wide archipelago in seconds. Sci-Fi and Weird Fiction Suites Beyond fantasy, donjon is the premier source for Star Wars (d6/d20) and Traveller star system generators. It also features a Weird Fiction section for Call of Cthulhu players, generating eldritch tomes, blasphemous rituals, and sanity-testing NPCs. The "Endless Oubliette" For GMs running "Megadungeons," this tool uses Dyson Logos-style geomorphs to generate an infinitely expanding dungeon. As players move through the map, the GM can keep generating new sections, ensuring the dungeon literally never ends. HTML and TSV Exports Almost every generator on the site allows you to export results as a raw text file or a portable HTML page. This is essential for GMs who want to copy-paste generated NPCs directly into Discord or import loot tables into Foundry VTT or Obsidian.

Drakar och Demoner

Beginner-friendly
Rules-light
Swedish
Drakar och Demoner ("Dragons and Demons," commonly abbreviated DoD) is Sweden's first and longest-running fantasy tabletop RPG, originally published in 1982 by Äventyrsspel (later renamed Target Games) as a translation and adaptation of Chaosium's Basic Role-Playing system and its Magic World supplement. It occupies roughly the same cultural space in Sweden that Dungeons & Dragons holds in the US - not just a game many Swedish players grew up on, but effectively the game that introduced the country to the hobby before D&D had any real distribution there.  Over four decades and roughly a dozen editions, the game shifted from BRP-style percentile play to a d20-based roll-under "Expert" system, passed through several owners including RiotMinds in the 2000s, and since 2021 has belonged to Free League Publishing, who crowdfunded a reimagined 40th-anniversary edition in 2022 known internationally as Dragonbane. Designed by the team behind Mutant: Year Zero and Forbidden Lands, with art by Vaesen illustrator Johan Egerkrans, this modern edition is what's currently in print and most widely played today.
