Hexcalibur
Pixel art editor with a live 3D preview, in your browser
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.
Hey Product Hunt! Solo founder here.
Hexcalibur started about a year ago as a tiny web app called HYBRUSH - just a canvas that wrapped your texture onto a spinning 3D cube, built for voxel game devs. This is that idea rebuilt properly: a full pixel art editor with a live multi-shape 3D preview, an animation timeline, and tileset tools with autotiling.
Here's the build story - first commit was May 5, launch was July 12. Ten weeks, one person, 823 commits - the editor plus the marketing site, docs, auth, billing, and cloud sync, built almost entirely with Claude Code. Happy to go deep on that workflow if anyone's curious.
One deliberate product choice: the editor itself has zero AI generation features. It's a paint tool - humans place every pixel. I lean toward AI improving the workflow around the art, not generating the art itself.
It's free to try in your browser, no install. I'd love to hear what you'd want from a browser pixel editor - and if you make game textures or tilesets today, tell me what your pipeline looks like. I'll be here all day.
the live 3d preview while painting block textures is honestly so satisfying, kinda wish i had this back when i was modding minecraft.
Tried the live 3D preview while painting and it actually made tweaking texture seams way less painful. The pack-based export to Tiled and Godot is a genuinely useful touch for anyone juggling multiple game projects.
the autotile tileset builder saved me a ton of time on a side project, super smooth workflow
