Pascal Editor: the in-browser 3D architecture editor that turns buildings into digital twins

Create, edit and share architectural projects from editor.pascal.app without installing heavy CAD: open source (MIT), over 17,000 stars on GitHub, npm packages and MCP server for AI agents.

Pascal Editor is a 3D architectural editor that works in the browser and promises to turn a property into a living digital twin: visualizing, organizing and managing every part of the building from a single three-dimensional canvas. Unlike traditional CAD suites, Pascal is committed to an immediate start—scan a space, import a model or draw from scratch—without a weeks-long learning curve.

What you can do with Pascal

The Pascal proposal is divided into three phases that the product itself describes on its website:

  • Create: Scan a space, convert it to 3D, or sketch a new project in the browser.
  • Edit: move walls, change furniture, test layouts and materials in real time.
  • Present: walk through the design in first person so that clients or colleagues "feel" the space before building it.

The community showcase on the cover shows everything from single-family homes to pavilions, churches or ranches—projects with thousands of visits—which confirms that it is not just a technical demo but a 3D publishing platform.

Capture, AI, library and render

Pascal is not limited to the web editor. The platform integrates several complementary pieces:

  • Pascal Capture — app for iOS that scans real spaces (available in the App Store according to the official website).
  • AI generation — sketches that are converted into solid geometry directly on the model.
  • Pascal Studio — advanced materials (glass, holographic, procedural) for eye-catching renders.
  • Asset library — thousands of 3D objects ready to place and modify.

Open source and developer packages

Pascal is distributed under the MIT license at github.com/pascalorg/editor. The repository exceeds 17,000 stars and is written mainly in TypeScript, with a Turborepo monorepo that separates the engine, viewer and editing application.

The packages published on npm allow you to integrate Pascal into other products:

  • @pascal-app/core — node schemas, scene state (Zustand), geometric generation and persistence.
  • @pascal-app/viewer — 3D rendering components with React Three Fiber.
  • @pascal-app/mcpMCP server for AI agents to read and modify scenes (rooms, objects, materials).

Version v0.9.0 added, among other new features, an IFC → Pascal importer, solid/realistic render modes, plugin architecture by node registration and an elevator system, according to official release notes.

For whom does it make sense?

Pascal fits very different profiles that the website itself lists: owners, architects, developers, contractors, video game designers, production teams, content creators, digital twin companies and developers who want to embed a 3D viewer without reinventing the engine.

For technical teams, the appeal is being able to clone the repo, run the local development environment, and publish their own extensions—or connect AI agents via MCP—without relying on a closed proprietary format.

How to get started

  1. Open editor.pascal.app and press Start building.
  2. Explore templates and community projects to see the level of detail possible.
  3. If you develop: check the repository on GitHub and the @pascal-app/* packages on npm.
  4. For field scanning: try Pascal Capture on iOS if you need to start from a real space.

In summary

Pascal Editor does not compete only with a desktop CAD: it is a web platform to model, edit, present and share 3D buildings, with open source and a community that already publishes real projects. If you're looking for a digital twin accessible from the browser—or an embeddable engine for your own app—it deserves to be on your radar.
