3dCMS is a browser editor and an MCP server for real 3D websites: you build navigable 3D pages by hand or by chatting with Claude, ChatGPT or any other MCP client, and publish them as crawlable HTML at the same URL as the 3D view. It is free to start, needs no code, and connects to an AI assistant through one URL: see Build a 3D website with Claude or ChatGPT.
3dCMS lets you build websites that are real 3D scenes. You work in a visual editor in your browser (dropping in objects, lighting them, wiring up materials) and then publish a live, navigable 3D page that anyone can visit. No Three.js code, no shaders, no asset pipeline to wrangle. One product does the whole job.
And here's the part that makes it a genuine CMS rather than a tech demo: every published page also serves clean, semantic HTML from the same URL. People get the interactive 3D view; search engines and AI search tools get a full, readable mirror of your content. Nobody gets cloaked.
Four ways to build
Most people reach for several over time, but any one of them gets you a scene:
In a hurry? You can also start from a template: clone a finished scene, already personalized with your name and photo, and reshape it.
Not ready to sign up for anything? Try the editor with no account at /try: it's the whole thing, and your scene comes with you if you decide to keep it.
Who it's for
3dCMS is aimed at web builders making the kind of site where flat HTML feels like it's leaving something on the table: portfolios, galleries, brand experiences, virtual showrooms, architectural walk-throughs, product launches. If you've ever wanted a page that someone can move through instead of just scroll, this is for you.
You don't need to know WebGL. You don't need to manage a build. If you can use a design tool, you can use 3dCMS.
What's in this knowledge base
This is the full manual, written to be read start-to-finish or dipped into. Some signposts:
- The quickstart takes you from an empty viewport to a published link in about five minutes. Start there.
- The middle sections are the deep reference: building scenes, modeling, materials, effects, the AI Assistant, publishing, and SEO.
- The reference at the end has the full keyboard-shortcut table, a glossary, an FAQ, and an honest list of what isn't built yet.
