The tools

Small in-browser tools and curated resource hubs for solo game devs. The sprite spec builder is interactive. The audio toolkit is a curation page. More tools shipping as content gaps surface.

Interactive · NEW Procedural · 100% in-browser

Procedural sprite generator

Click "regenerate" until you find a sprite you like. Pick subject (creature, robot, character, item), size, palette. Each sprite has a seed you can save or share via URL. Output is CC0 — drop it into your jam build, recolor it, ship a game with it. Generation runs entirely in your browser; nothing's uploaded.

Interactive For 8-directional and isometric

Sprite spec builder

A form-driven tool that generates a personalized blank sprite sheet template, an AI image-gen spec doc, and an engine-side Claude prompt. Upload your sprite to preview it slotted into every direction, with auto-mirroring for left-facing cells. For Unity, Godot, Phaser, LOVE2D, and Pico-8.
