Pascal Editor

Pascal Editor is an open-source 3D architecture editor from Pascal Group. In the browser you draw walls, add windows and place furniture to build a scene, on top of React Three Fiber and WebGPU.

You can connect your own AI agent through its CLI and MCP, so the agent models and edits the scene directly. There is also a Pascal Next preview that isn't yet part of the open-source release.

Who it's for:people working in architecture, interior design or 3D scenes who want an AI agent to help with modeling. You'll need to be comfortable with a command line.

Before you start: you launch it locally through a browser or the CLI; the CLI requires specific minimum versions of Node 22, 24 or 26, and you can also self-host in a container. Using MCP locally needs no Pascal account or API key and doesn't upload your project. An optional hosted service needs an API key, stored in your system keychain; its pricing isn't stated. The code is MIT licensed, and the Next preview's demo media is CC BY 4.0. The interface is in English.
