Traveller 2E (2016)

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.

Inkroll is a web platform for playing tabletop RPGs play-by-post: asynchronously, in written posts, on each player's own schedule, with a human gamemaster running the table. It sits between heavyweight real-time VTTs and plain forum software; the writing stays the point, but the platform actually understands characters, dice, secrets, and the GM's role instead of leaving them on the side. It is also, deliberately, a beautiful place to spend a campaign. Inkroll was built by play-by-post players who wanted the game to read as well as it plays: a calm, candlelit page of ink and parchment where posts get the space of a book, quoted speech and images are cleanly styled, and every table can choose the look and post layout that suit its story. The tools stay out of the way until the moment a hand reaches for them, so a session feels like reading and writing a novel with friends, not operating software. Dice are typed straight into a post, like {Perception:1d20+2}, rolled once on the server the moment the post is published, then frozen, with a per-post audit the whole table can see, so a result can never be edited or quietly re-rolled. Players post as their characters, with portraits, versioned character sheets, and quick stat updates (hit points, spell slots, conditions) committed together with the post. GMs get sealed passages delivered to exactly the players they choose, chapters, scene notes with a world map and a per-chapter battle map, and live updates with typing indicators and read markers, so an asynchronous table still feels alive. Long campaigns are first-class citizens: the Chronicle keeps a running recap of every chapter and every character met, and answers questions from the campaign's own posts, so a returning player or a newcomer catches up in minutes. And because a campaign written like a book deserves to become one, a finished game can be exported as a designed, print-ready PDF or EPUB. Games already in progress can be imported from Myth-Weavers or Discord with posts, characters, images, and dice results intact. Ready-made sheets cover D&D Fifth Edition, Pathfinder 2e, Call of Cthulhu, Shadowrun, and Grimwild, plus a system-agnostic option and a builder for custom rulesets with their own dice mechanics. New systems are also gladly added upon request. A reading-first page with a crafted ink-and-parchment look, and per-campaign styles and layouts Server-rolled, tamper-proof dice with a table-visible audit Post-as-character with versioned sheets and inline stat updates Secret passages sent to exactly the chosen players World map, battle map, and scene notes beside the composer The Chronicle: a running recap plus Q&A over the campaign's own posts One-click import from Myth-Weavers and Discord Book export to print-ready PDF and EPUB, full campaign export as json so no lock-in Links inkroll.gg - Official website discord.gg - Discord server reddit.com - r/inkroll subreddit
