Motestack review
A free web editor with animation, indexed color, tile tools, and game-ready exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Motestack is a browser-based pixel art and 2D animation editor for indie game developers, pixel artists, and retro enthusiasts. Its feature set covers pixel drawing with pencils, shapes, gradients, dithering, fills, erasers, and custom brushes, alongside layers, groups, blend modes, opacity, and cross-frame layer linking. Projects run client-side in the browser, with editable .mstack files and exports for PNG, GIF, sprite sheets, project JSON, and other project work.
Animation is a central strength. The frame-based timeline supports ordering, duplication, durations, and tags, while onion skin overlays show neighboring frames during editing. Indexed-color mode adds palette locking and palette-wide recoloring for workflows that require controlled color use. Motestack also includes 47-tile auto-tile sheet generation, making it relevant to tilemap-oriented game work rather than only standalone sprite creation.
The published documentation describes Motestack as beta and as a personal hobby project. Its v0.15.x documentation says all features are enabled, and the product is available as a free web editor. Support is provided through documentation. Solo creators and small teams looking for browser-based animation, indexed-color editing, and game-development exports should find the scope well aligned with those needs. Teams requiring a desktop application, broader support channels, or a product positioned beyond beta should consider a different tool.
