Summary

Hexcalibur is a browser-based pixel-art editor for voxel-game textures, combining drawing tools with 3D previews, animation, tilemap editing, and export presets. Its preview can show artwork on a rotating cube and an L-shaped arrangement to inspect how textures meet across faces. Packs group textures, a palette, and references, so assets can share a palette. The animation timeline supports onion-skinning and named tags, with GIF, APNG, and sprite-sheet export listed. Tilemap tools let users import or draw tilesets, stamp tiles, edit map tiles, and replace or clear a tile throughout a map. Export presets cover Minecraft Java and Bedrock, Tiled, and a TexturePacker JSON-Hash atlas for Phaser, Babylon, Godot, Three.js, and Unity; raw per-face ZIP and custom export are also listed. The free plan supports one pack and up to eight assets, with a single-cube preview and five animation frames. Free artwork stays in the browser; Pro adds cloud sync. A free Axidus account is required, and phones are unsupported. Paid plans start at $5/mo.
