This is the creative side of ToolFluency — a procedural toolkit for the kind of person who's prototyping an indie game on a Tuesday night, sketching dungeon tiles for Friday's D&D session, or designing a miniature to print before the weekend. These aren't AI image generators and they aren't pro-grade DCC suites. They're focused, browser-based generators and editors that let you produce usable assets without installing Blender, paying for Aseprite, or learning a 200-button UI before you can ship anything.

The variety covers most of what a small game project needs. The Pixel Art Maker is a grid editor with palette presets like NES, PICO-8, and Game Boy and exports clean transparent PNGs. The Voxel Builder is a Minecraft-style cube editor with a 64-cubed grid and JSON export. The 3D Character Builder generates parametric characters across 54 archetypes. Asset mixers spin out endless variations of avatars, creatures, ships, foliage, dungeon tiles, potion bottles, and fantasy map icons from a single click. The Tileset Maker and 2D Game Maker let you build a level using the Kenney New Platformer Pack and ship a playable level on the same afternoon you started.

Export formats match the destination. STL, OBJ, and glTF for 3D printing or game engines. PNG and sprite sheets with TexturePacker JSON sidecars for sprite-based engines. Every tool can save its output to My Assets with a free account, so the work you produce in one tool — say a pixel sprite from the Pixel Art Maker — becomes available to the next, like the 2D Game Maker dropping it into a level. It's a connected suite, not eighteen disconnected one-offs.

Modular dungeon tile generator for VTT battle maps — Roll20, Foundry VTT, Owlbear Rodeo. Export tile packs in pixel art or sketch style with consistent grid alignment.
🎮
2D Game Maker
Drag-and-drop level builder for the Kenney New Platformer Pack. Place tiles, add enemies and pickups, set spawn and goal — playable in-browser the moment you save.
⚔️
2D Game Builder PRO
Advanced level builder with custom blocks, enemies, physics tuning, and asset library integration. Assemble levels using sprites you've made — every saved sprite becomes playable.
FAQ

Common questions

Quick answers to what indie devs and tabletop creators ask first when they land on a creative tool page.

In most cases, yes — but check each tool's footer for the specific license. Procedurally generated output is released as CC0 (public domain) or under permissive terms with no attribution required, meaning you can sell games and assets that contain it without paying ToolFluency anything. Tools that build on third-party content (like the 2D Game Maker using Kenney's New Platformer Pack) inherit that source's license — Kenney packs are CC0, so those are also commercial-friendly. Anything you draw, paint, or build from scratch in the editors is entirely yours from the moment it's made. We make no claim on your output, ever.
Yes. 2D tools export PNG plus sprite sheet PNGs with TexturePacker-format JSON sidecars — Unity, Godot, Phaser, PixiJS, and most 2D engines import that format directly. 3D tools export glTF (the modern web and game format used by Three.js, Unity, Unreal, and Godot 4), OBJ (universal — Blender, Maya, every major DCC tool), and STL (3D printing standard). The 3D Character Builder exports rigged glTF that you can drop directly into a Unity or Godot project and animate. For voxel models, route through the 3D Shape Builder to convert to a watertight mesh first.
The 3D builders are designed with 3D printing in mind. Precision Lathe guarantees manifold output for revolved parts like bottles and handles. 3D Shape Builder runs every export through a mesh repair pass that fixes degenerate triangles, merges duplicate vertices, and re-orients face normals — STL files come out clean and slice-ready in Bambu Studio, Cura, PrusaSlicer, or OrcaSlicer. Voxel models route through Shape Builder for STL conversion. Print-in-place clearances are baked into parametric parts where appropriate. For mini-painting and tabletop terrain, the chunky voxel and lathe outputs print especially cleanly with no support material needed.
Every creative tool can save its output to My Assets — your personal asset dashboard inside the 3D Assets Suite. You'll need a free account to keep work across sessions and devices. Each save stores the model or sprite plus a thumbnail and metadata, and groups into Collections so you can organize a game project's assets together. You can also export the file directly to your computer at any time without an account — the local download path is always available alongside the Save button. Files saved locally are also restorable by re-importing them into the same tool.
It depends on the tool. 2D tools export PNG (transparent, lossless) and sprite sheets (PNG + JSON sidecar). The Foliage Mixer and Cartography Mixer also export SVG for print-quality scaling. 3D tools export STL (3D printing), OBJ (universal 3D), and glTF (modern web and game engine standard). The Voxel Builder exports a sparse-grid JSON of cube coordinates plus a PNG screen capture; route into Shape Builder for STL or glTF. Any tool that operates on game-engine-ready output uses widely supported formats — no proprietary file types, no vendor lock-in.
The Pixel Art Maker supports canvases from 8×8 up to 256×256 pixels — covering everything from tiny inventory icons to large character portraits and detailed environment art. The Sprite Sheet Maker can pack frames of any size into sheets up to 4096×4096 (engine-safe). For genuine full-screen illustrations beyond pixel art, use the 2D Sketch Pad or work at high resolution in Pixel Art Maker and downsample on export. Performance stays smooth at all canvas sizes since everything renders locally in the browser with no round-trips to a server.
Absolutely — tabletop is one of the main use cases. The Dungeon Tile Mixer and Cartography Mixer output tile packs and map icons that drop straight into Roll20, Foundry VTT, Owlbear Rodeo, and Inkarnate. The Potion Bottle Generator creates bottle PNGs for inventory cards and 3D-printable STLs for physical props. Precision Lathe and 3D Shape Builder produce printable miniatures, terrain pieces, and dungeon furniture in the 28mm to 32mm scale range. Voxel-built castles can be printed at 1:32 scale for wargaming with no support material since every face is axis-aligned.
2D tools (Pixel Art Maker, Sprite Sheet Maker, Image to Pixel Art, mixers) work well on tablets — touch input maps cleanly onto pixel grids and stylus support is reliable on iPad and Android tablets. The 3D tools (Voxel Builder, Shape Builder, Precision Lathe, 3D Character Builder) are best on desktop or laptop because orbit controls, boolean operations, and mesh repair are CPU and GPU intensive — they technically run on tablets but the experience is more comfortable with a mouse and keyboard. Phone-sized screens are usable for the simpler mixer tools (avatar, creature, ship, foliage, potion) which are mostly randomize-and-export workflows.
