StarCar is a permanently free linear star systems cartography tool. It enables GMs running sci-fi campaigns to visualize and share star maps with their players easily. It allows a lot of different customizations for orbital bodies, like planets, secondary stars, Ringworlds, Dyson Spheres, and more. GMs can add notes to individual orbital bodies, stars, and moons. The notes can be totally customizable, or use either Traveller or Stars Without Number rules. If they want, the GM can even export a stylized PDF report that details all the notes in an easy-to-follow format. And if the GM just needs something right away? StarCar will roll the dice and generate a totally randomized system: random stars, planets, and even randomized plot hooks. Once the GM is finished, they can export it in a number of different formats: PNG, WebP, or JPG, or with settings like Printer Friendly or Transparent Background. Anything exported is licensed under Creative Commons 4.0, which means the person who makes it owns it. They can even use it in any products they sell, with attribution.

Merak is a map maker for worldbuilders. Five kinds of map live in one document: a political map of Earth, an editable Earth with real terrain, a blank world, a fantasy map and a city board, and factions, units, labels, cities and lore carry across all of them. Land can be raised, lowered, smoothed, flattened, roughened and worn down with droplet erosion; biomes paint on top; a thin river tool cuts channels without shattering the coast. The world generator builds plates, mountain chains and weathered coastlines from a single seed, and the Planet Advisor checks whether the result could exist at all, whether rivers have anywhere to drain, whether the biomes suit their latitude. An elevation probe reads back true metres and slope, and any map can be viewed in 3D or wrapped onto a shader globe. Custom empires are drawn freehand with a lasso, and a coast mode clips the outline to the actual shoreline so borders follow the water instead of cutting across it. The arsenal and battle system has faction tinting and stacking counts, alongside commanders carrying portraits, ranks, decorations and an order of battle. Operational arrows play out as scripted advances with per-province combat. On a battle map, Fight animates the whole clash: infantry and armour close to melee under a counter system, artillery bombards from range with splash damage, aircraft strike fast and hard, and badly wounded units break off to a field hospital, heal, and return to the line. The timeline holds the progress of the map over the years. Lore notes form a small in-map wiki placed anywhere or pinned to a city, unit or flag, and linked to one another. Raster paints layers with blend modes, pressure and grain; an Asset Studio for custom symbols; flag and insignia makers; a colour studio. Finished maps exported as PNG up to 16K.

Worldographer is the easy to use world, kingdom, city, village, dungeon, & battlemat map maker for Dungeons & Dragons (D&D) and other role-playing games (RPGs). Make maps from scratch in minutes or let the program auto-generate a map you can quickly customize. Next Level Map-Making By keeping the software focused on a few specific map styles, the maps are easy to create and modify. Useful generators will auto-generate many types of maps: a world, region, city, village, shop, house, and more! Hundreds of icons are built into the software, but with the pro version you can add even more. We've made thousands in other map icon packs, but any common image (.png preferred, but .jpg & .gif can also be used) can be added.

Fantasy Grounds Unity is a high-power virtual tabletop originally released in 2004 and completely rebuilt on the Unity engine in 2020. Developed by SmiteWorks, it is the industry pioneer of "automated play," where the software handles complex rules, modifiers, and combat math natively. In a massive industry shift in late 2025, the platform moved to a completely free-to-play model, removing the traditional $50 license fee to compete directly with modern browser-based rivals. Description Fantasy Grounds is often described as a "Digital Dungeon Master’s Assistant." It is a standalone application (not a browser site) that provides the most stable and deep automation available. While it has a more traditional, window-based interface that can feel daunting to new users, it rewards the "Power GM" with unparalleled control over combat and data. Since becoming free in late 2025, it has positioned itself as the premier "zero-cost" entry point for groups who want professional-grade automation without a subscription. System Overview & Key Features Native Ruleset Automation Unlike other VTTs that rely on community plug-ins, Fantasy Grounds features "Hard-Coded" automation for its primary systems. When a player drags an attack onto a target, the software automatically checks for cover, calculates the hit against Armor Class, applies damage, and tracks temporary hit points or resistances without any manual input. V5.1 Visual Intelligence The 2026 update introduced "Aggregated Notifications." Instead of scrolling through a wall of text in a chat box, combat results like damage, saving throws, and status effects now appear as elegant visual icons and pop-ups directly over the tokens on the map. 2.5D Tactical Mapping While it supports traditional 2D top-down maps, FGU includes a unique 2.5D camera mode. This provides a sense of depth and perspective to battlemaps, making the digital table feel more like a physical diorama with "placeable" 3D-like objects like trees and furniture. Total Offline Capability Because it is a localized application, you can prepare your entire campaign, build NPCs, and write story entries without an internet connection. Your data is stored on your hard drive, giving you total ownership of your campaign files. The Fantasy Grounds Forge FGU features an integrated marketplace and community portal called "The Forge." This allows GMs to browse and auto-install thousands of community-made extensions and themes that update automatically whenever the main software is launched. Cross-Platform Unity Engine Built on the Unity 6 engine (as of 2026), the software offers smooth performance on Windows, macOS, and Linux. It uses hardware acceleration to handle complex dynamic lighting, weather effects, and large-scale vision blocking for massive dungeon crawls.
