3D Printing Tool

OpenSCAD Online Playground

Use this OpenSCAD online playground as a browser-based OpenSCAD web editor with no installation. Write or paste code, render a live 3D preview, and download the result as a .scad file or STL on your device.

The OpenSCAD engine runs in your browser and renders the code from the editor.

How to use this tool

1Write or paste OpenSCAD code into the editor.
2Click Render preview to build the model in the live viewer.
3Download your code as a .scad file when you are ready to save or share it.

Playground notes

Preview rendering runs locally in your browser. Your code is never sent to our servers. BOSL2 includes load on demand, common threads.scad paths are bundled, and other external libraries still need to be inlined. Keep in mind that large or complex scripts can take longer to render.

Run OpenSCAD in your browser - no install required

OpenSCAD online tools are useful when you need an OpenSCAD web editor with no installation: a work laptop, a Chromebook, a tablet, or a friend's PC. This page is the writing space - test a snippet, tweak a module, paste generated code, or build a small parametric part directly in the browser.

That's what this playground is for. The full OpenSCAD engine runs in your browser via WebAssembly. You get a code editor, a live preview you can orbit, and one-click export of both your .scad source and a rendered STL. No account, no queue, no server-side rendering - the same engine that powers the desktop app, running on your hardware.

Just need to preview an existing file? Try the OpenSCAD Viewer instead.

What you can do here

Write code from scratch or paste in an existing script. The editor ships with a small sample so you can hit Render and see the pipeline work before writing a line. Typical uses:

Testing a module or snippet before adding it to a bigger desktop project.
Tweaking parameters on a downloaded .scad file when you're away from your main machine.
Learning OpenSCAD basics - primitives, translate, rotate, difference, union - with instant visual feedback.
Rendering quick one-off parts to STL: spacers, washers, simple brackets, test cubes.
Sanity-checking generated code from our SVG to OpenSCAD and DXF to OpenSCAD converters.

Privacy: your code stays on your device

Everything renders locally in your browser. Your code is never sent to our servers - relevant if you're prototyping commercial designs or client work in SCAD. The flip side of local rendering: complex models with high $fn values, big minkowski() operations, or heavy boolean trees can take a while on slower hardware, the same way they would in the desktop app. If a render times out, drop $fn, simplify the booleans, and add detail back gradually.

Browser playground vs desktop OpenSCAD

The desktop app is still the right home for serious multi-file projects - it has the customizer panel, broad library setup, font handling, and faster rendering on big models. Think of the playground as the scratchpad: fastest possible loop from "I wonder if this works" to a spinning preview, anywhere you happen to be.

Frequently asked questions

Can I use OpenSCAD without installing it?

Yes - this playground runs the real OpenSCAD engine in your browser through WebAssembly. Write code, render previews, and export STL files with nothing installed.

Can I download an STL from the browser version?

Yes. Render the model first, then use the STL button. The export comes from the same render the preview shows.

Does this support OpenSCAD libraries like BOSL2?

Yes for BOSL2 paths such as include <BOSL2/std.scad>, plus common threads.scad paths used by printable screw-thread models. The playground loads BOSL2 in the browser when your code references it, and bundles threads.scad the same way the OpenSCAD Viewer does. Other external libraries still need to be inlined or opened in the desktop app.

Why is my render slow or timing out?

Same reasons desktop renders crawl: high $fn, minkowski(), nested booleans on dense meshes. Lower the detail, render, then step it back up. Browser rendering also depends on your device - phones take noticeably longer than desktops.
