About Parohub

Parohub is the home for 3D printing files — a version-controlled, collaborative platform built for makers, engineers, and designers.

What we do

We give 3D models the same care as software source code. Every upload creates a new version. Your full history is always preserved, branching and forking are first-class operations, and you can see exactly what changed between revisions — directly in your browser, overlaid in two colors.

Who it's for

Makers & hobbyists

Store all your personal projects in one place. Never lose a revision again.

Professional studios

Collaborate on complex assemblies across a team with private repositories.

Open source designers

Share your models with clear licenses so others know how to use and remix them.
