Our verdict on Nerulio Sprite Editor
Nerulio Sprite Editor is a browser-based workspace for preparing game sprites and related assets. It suits solo and small-team web artists who need to draw pixel art, assemble animations, define collision data, build atlases, and export files for engines. Imports cover sprite sheets, numbered frames, GIF, APNG, and Aseprite projects. The Pixel workspace combines pencil, bucket, shape, and selection tools with layers, blend modes, indexed palettes, and onion skinning. Sprite and tile workspaces extend the editor beyond single-image drawing.
Animation and engine preparation are the standout areas. An animation timeline supports tags and per-frame durations, while each frame can receive pivots, hitboxes, hurtboxes, and collision polygons. Atlas packing includes trim, padding, and multipack options. Export formats include PNG, GIF, APNG, Aseprite files and JSON, CSS sprites, and engine-oriented bundles for Godot 4, Unity 6, Phaser 3/4, PixiJS 8, Spine/libGDX, Starling/Sparrow XML, LÖVE, and Defold. Integrations also name Aseprite and GameMaker, although GameMaker export is marked unverified by the vendor.
All features are free, and no export is held back, so the product presents a broad toolset without paid tiers to compare. Projects are stored in the browser and can be saved as Nerulio files; the vendor says files are not uploaded. That approach fits artists who prefer a cloud-delivered editor with local-in-browser project handling. The web-only platform may be less suitable for teams seeking a native desktop application or shared workspace, and users targeting GameMaker should validate that export path before committing. Choose Nerulio for an all-in-one browser workflow from pixel drawing through engine bundles; consider another editor when native deployment or verified GameMaker output is essential.
