FreeMoCap is a free, open-source, markerless motion capture system that uses ordinary cameras (webcams, GoPros, smartphones) to record and reconstruct full-body 3D movement of humans, animals, and robots. It combines a Python processing server with an Electron/React GUI, calibrating multi-camera setups with a ChArUco board and exporting results to CSV, FBX, and Blender formats.

Use cases

• capture full-body motion with just webcams
• markerless motion capture for biomechanics research
• record 3D animation data for Blender or game engines
• track human movement for sports and athletic analysis
• synchronize multiple cameras for 3D pose reconstruction
• affordable motion capture without expensive hardware
• analyze gait and movement for scientific studies

When to choose

• you need research-grade motion capture at zero cost using everyday cameras
• you want exports compatible with Blender, FBX pipelines, or CSV analysis
• you're doing biomechanics, animation, sports, or robotics movement research
• you prefer local processing without cloud services or proprietary hardware

When to avoid

• you need real-time mocap for live game engines or streaming avatars with ultra-low latency
• you require sub-millimeter precision of optical marker-based systems like Vicon
• you need facial or finger tracking at production fidelity
• you want a fully polished turnkey product with no setup or calibration
