If you're looking for a Mixamo alternative, you usually want the same outcomes: a clean skeleton, decent skin weights, and an easy way to get your character moving inside Unity or Unreal. The tricky part is that your character might not be a perfect "game-ready" mesh yet, or it might come in GLB/FBX/OBJ and you don't want to spend hours fixing pipelines.
autorig.online is a lightweight online tool focused on a simple goal: take a character in T-pose, run automatic rigging, and export results you can immediately use in real projects.
What you get
- Rigged model (skeleton + skin weights)
- Animated exports (ready-to-import files for popular pipelines)
- Multiple formats depending on your pipeline (GLB, FBX)
- Preview video of the rig/animation result (handy for sharing and quick checks)
When a Mixamo-style workflow makes sense
Automatic rigging is perfect when you need to:
- prototype a game character fast
- test multiple characters and pick the best
- get a baseline rig before doing manual polish
- convert assets to match Unity/Unreal requirements
What matters most: T-pose and clean geometry
Most auto-riggers fail for predictable reasons. If you want good results, focus on these basics:
- True T-pose: arms straight out horizontally, legs straight, neutral face
- Correct scale: avoid extreme tiny/huge scales and weird unit conversions
- One character: remove extra props/scene clutter if possible
- Clean mesh: avoid broken normals, duplicate faces, or non-manifold geometry
Unity vs Unreal exports
Many "rigging online" tools stop at "here's a rig." A production pipeline usually needs more: correct orientation, bone naming expectations, and export formats that won't fight your engine. If you're targeting Unity, a Unity-friendly FBX export is usually the smoothest. For Unreal, an Unreal-friendly FBX export typically reduces import friction.
How to use it (quick steps)
- Upload your model (GLB/FBX/OBJ) or paste a direct link.
- Start the rigging process.
- Watch progress and download the rigged/animated results.

FAQ
Is this free?
You can try free conversions, and then continue with an account/credits depending on your site rules.
Do you support non-human creatures?
Auto-rigging works best on humanoid proportions. Creatures can work, but results vary depending on anatomy and pose.
Does it replace manual rigging?
For many use cases (prototyping, quick NPCs, previews), it can. For hero characters, manual polish is still common.
