Hexcalibur is a browser-based pixel art editor for game artists. Paint block textures in 2D and watch them update live on a 3D block, animate sprites on a frame-by-frame timeline, and build tilesets with autotiling. Everything is organized as packs - manage and export a whole texture set as one unit, with engine-aware exports for Minecraft (Java + Bedrock), Tiled, Godot, Unity, Three.js, and Babylon. No install, humans place every pixel. Free to start, Pro when you need more.
