Sample circuits

Ready-to-run example circuits you can open directly in the app. Each sample is a samples/<name>.numasim.json file in the repo, loaded into the editor with a single click.

TIP

The full gallery is auto-generated from the samples/ folder. See the sidebar for the complete list, or browse the categories below.

How to open a sample

Click any sample's "Open in app" button. The app launches with the sample pre-loaded and ready to run. You can edit it, save your own copy, or just click Run to see it in action.

The URL pattern is:

https://www.numasim.com/?sample=<id>

where <id> is the sample filename without the .numasim.json extension.

Categories
