Browser-based tools for Phaser, PixiJS and Unity developers
These tools replace desktop-only software for common game development asset tasks. The Texture Packer produces Phaser, PixiJS and Unity-compatible JSON alongside the packed atlas PNG — the same format as TexturePacker desktop, for free. The Bitmap Font Generator exports AngelCode-compatible .fnt + PNG spritesheets that PixiJS and Phaser load natively.
The Physics Editor provides a visual interface for drawing polygon, circle and box collision shapes on top of your sprites, exporting coordinates ready to paste into your engine. All tools run in your browser with no install and no project lock-in.
