Profile

Built this because I kept needing a quick sprite sheet tool while working on side projects and everything either required a download or had a paywall.It runs fully in the browser, no upload to a server, no login. Supports: - Packer mode: upload separate frame PNGs, reorder them, export as atlas + JSON - Slicer mode: upload an existing sheet, define rows/columns, split into frames - JSON metadata compatible with Phaser, custom WebGL renderers etc.Works with Unity and Godot workflows too. Would love feedback on what's missing.

The company sits in the show hn launch segment, where it competes on its core product or service.

It is recorded at the Show HN launch stage.
