Model fast.
Build solid.
A modern, multiplayer 3D modeler: add, subtract, snap, iterate. No installer. No license servers. No 2003 UX.
The full modeling demo is best on a laptop. Open it in a new tab when you are ready to push, pull, snap, and iterate.
Launch demoModern tech meets simple 3D
Fast modeling loops, extensible projects, and native collaboration.
Simple solid modeling
Geometry is well structured while still being flexible to model within. Everything in 3D is a watertight solid.
APIs, MCPs, and plugins (oh my!)
Built to be built upon. Modelcore's geometry engine is getting easier and easier to direct with prompts, but still a work in progress.
Real time collaboration
Model in the same scene with your colleagues. While you edit part of the model it's locked for others, greatly reducing model conflicts.
Join the early beta
We're inviting 50 founding members. Free during beta. Active development, informed by in-app feedback.
Request accessBeta covers core modeling + geometry tools. Data may change. Export important work regularly.

We are building this in public.
Modelcore is early. You can try the demo and read the changelog before you ask for access. The beta cohort is intentionally small while the tool is still changing quickly.
