Ludo releases free, open-source toolbox that lets AI coding agents prepare game assets for engines

32 offline tools in the Ludo CLI take care of setup work such as sprite pivots, collision shapes, palette swaps, seamless tiles, and looping sounds, with no account or credits needed

Seattle, WA, 10 November 2026 – Ludo.ai, the developer’s companion for creating production-ready game assets, today announced the Ludo Toolbox, a set of 32 free command-line tools that give coding agents such as Claude Code, Codex, Cursor, GitHub Copilot, and Gemini CLI the measurements and engine files they need to add sprites, images, sounds, and 3D models to a game. The toolbox ships inside the Ludo CLI, Ludo’s tool for generating game assets from the terminal. The CLI is open source under the MIT license, and the toolbox runs entirely on the developer’s own machine, offline, with no account, API key, or credits required.

Coding agents now write much of a game’s code but still have to guess when it comes to the art: where a sprite's anchor point sits, how big its collider should be, how many pixels make a meter, and whether an animation loops smoothly. The toolbox replaces these guesses with exact numbers. Each tool returns plain structured data (JSON) and writes the engine’s own files, allowing agents to give the same answer on each run without spending tokens on writing their own throwaway scripts.

 

Automatically chain tools from a prompt

 

A developer can describe the job in a single sentence. Asked to set up a knight character in Unity with the pivot on its feet, a collider that leaves out the sword, and a height of 1.8 meters, the agent chains three tools. It measures each of the knight's spritesheets and picks one pixels-per-unit scale for all of them, fits a box and capsule collider to the body without the blade, and writes the Unity files that anchor every frame to its feet. The same numbers come out for Godot, Phaser, and Box2D, plus a TexturePacker atlas for Phaser and PixiJS.

 

Jorge Gomes, Co-Founder and CTO of Ludo.ai, said: “Coding agents are very good at game code, but they still eyeball the art. The toolbox gives them the numbers instead, like where the pivot goes, how big the collider is and whether a loop closes. We made it free and open source because every game project has this work to do, whatever made the art.”

What’s in the toolbox:

 

  • Set characters up for the engine: Place anchor points (pivots) on the ground line, fit hit shapes (colliders) such as boxes and capsules, set one pixels-per-unit scale across a character’s sheets, and export to Godot, Unity, Phaser, Box2D, and TexturePacker

  • Prepare spritesheets: Slice a sheet into frames or join frames into a sheet, bring a character’s moves to one frame size with the feet on one ground line, score how well a loop closes, and export a GIF, WebM, MOV, or MP4 file

  • Polish pixel art and textures: Recolor art to any palette from the Lospec pixel art library, swap colors, add outlines and drop shadows to every frame at once, check that a texture tiles without a seam, and write tilesets for Tiled, Godot, and Unity

  • Check sound files: Read length, loudness, true peak, and a song’s tempo, confirm a sound loops without a click, and trim with short fades

  • Inspect 3D models: Read a 3D model file’s (GLB) triangle count, textures, rig, and animation clips, find which way it faces, and work out how fast to move it so the walk’s feet don’t slide

  • Audit asset folders: Run the asset manifest report across a project’s asset folder to see what every file is and what’s missing, such as a move that the other characters have, a rig, or an animation, along with the Ludo command that adds it

 

The toolbox works on any asset, whether it was made with Ludo or not. Spritesheets made with Ludo carry a stamp with their grid, so the toolbox reads it straight away. On other sheets, it detects the grid itself and stops to ask rather than guess when it isn't sure.

 

Availability

The Ludo Toolbox is available now, free, in Ludo CLI 0.2.0 and later, which requires Node.js 20 or newer. Developers can install or update the CLI with ‘npm install -g @ludoai/cli’ and teach Claude Code every tool with ‘ludo skill install’. Codex, Cursor, GitHub Copilot, and other agents that read skills can add the toolbox with ‘npx skills add Ludo-AI/ludo-cli’.

 

The toolbox builds on the Ludo CLI, announced in October. When a task calls for new art, ‘ludo login’ lets the same CLI generate it, with generation included on Ludo.ai’s Pro and Studio plans.
