The Star Wars D6 Character Generator is a web app for creating characters, droids, ships, vehicles, and NPCs for the Star Wars D6 2nd Edition Revised & Expanded System and REUP. All data is stored locally in the browser and can be exported and imported as JSON. The application can be used entirely locally and offline. With a hosted installation, user accounts are also available. These allow you to share created characters, droids, ships, and other content with other users. (Requires an account) You can also create gaming groups where players can submit their character sheets to the game master for approval. (Requires an account) All you need to create an account is a username and password. Special thanks go to Chance Gibboney. Without his Character Generator Excel spreadsheets, the idea for this project would likely never have come about. His spreadsheets were used by the developer and his gaming group for many years and formed the basis for the development of the web application. The project is actively being developed and is available on GitHub under the MIT license

Since I’ve been working on a Savage Worlds setting for quite some time and started a new online group now, the topic of combat and initiative naturally came up. I used to use the SavageBot on Discord, but unfortunately, it doesn't really work properly for combat anymore. I didn't want anything overly complicated. I came across the "Savage Tracker" by Inspired Conviction - a simple browser-based tool. However it unfortunately no longer works. So, I wrote my own tool. It's available in English and German. Maybe it will be useful to someone.

Playing Mystic Empyrean online isn't easy because of their special use of playing cards. With this tool, you can draw and reshuffle the World Balance cards and even modify them (for instance, if a specific paradigm calls for it). The tool is bilingual (German & English) and allows you to create and save your own realms. Naturally, you can also access realms created by others. Currently, we have included a basic "seed world" and the world of Nitar, as described in the rulebook.

For anyone playing a female character in The Dark Eye (Das Schwarze Auge) who doesn't want to keep track of when their character is menstruating, I’ve written a tool that displays the next twelve occurrences. The calculations are based on the Calendar of the Twelve Gods, which is the most widely used calendar in Aventuria. I assume a 28-day cycle, with the period typically lasting one week.

This is the official character manager and generator for the Uniworld TTRPG system. With this tool, you can create and manage your Uniworld characters and avatars, including leveling up and exporting. Available export formats include PDF and JSON for the HTML character sheet.

This is the official HTML character sheet for Uniworld. You can load and save your characters online directly on the website or download the sheet and do it on your device.

VVD is a visually driven world-building and campaign management platform launched in 2024. Created by an independent developer, it positions itself as a streamlined, "distraction-free" alternative to complex wikis like World Anvil. In 2025, the platform gained massive popularity on social media for its "clean UI" and its strict No-AI pledge, promising that all art and assets on the platform are created by human artists.  Description VVD is built for the "sparks of inspiration." It uses a card-based system to organize NPCs, locations, and magic items, allowing users to connect them visually through an interactive graph. Unlike traditional folder-heavy organizers, VVD feels like a digital corkboard or a personalized Wikipedia that prioritizes aesthetics and ease of use. It is a web-based tool, meaning it requires an internet connection, but it is highly optimized for mobile devices, making it a favorite for GMs who need to jot down world-building notes on the go.

Item Forge is a small free tool to help GMs to create printable item cards for their table. It is optimized for D&D and Shadowdark. You can quickly fill out the form and it will generate a nice card design. There are predefined templates in D&D, Shadowdark and printer friendly style. You can also use the custom template where you can design it with CSS yourself. There are various export options, from PDF to images and a backup as json. For quick sharing there is a publish option which gets you a link that you can share with other GMs. Item Forge is translated into 10 languages currently and keeps growing.

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).
