Sandbox Demos
Build pixel-perfect sandbox demonstrations with HTML and CSS cloning. No staging environments, dev tickets, or maintenance required.
What are Sandbox Demos?
Sandbox demos are interactive, HTML-based replicas of your product that behave like a live environment — but without the risks of using production or staging data. Viewers can click, type, scroll, and explore freely, just like in the real product.
Before diving into creating a sandbox, we recommend watching this 4-minute overview to get familiar with this feature:
Otherwise, here's an example Sandbox Supademo:
How to Create a Sandbox Demo
Setup Tips and recommendations prior to recording:
Record using Google Chrome. Chrome is the best-supported browser for demo recording.
Refresh the page prior to recording by re-loading (command+R). Stale pages that have been inactive for 20+ minutes may lead to unexpected issues.
Record at full width and height (or with 1280x800 dimensions) on a laptop for an ideal viewing experience. Recording on large monitors may lead to small UI elements or illegible text.
Close unnecessary tabs (especially in the same Chrome window). Having lots of tabs open is a surefire way to slow things down and can impact capture speed.
Slow down between captures (especially for HTML recording). HTML recording needs a moment to capture each page’s HTML + CSS. Pause briefly between clicks so each step finishes processing—this may take longer on complex pages or if you have many tabs open.
You can create sandbox demos in two ways:
1. Record Sandbox Demos with Auto-Linking
Open the Supademo Chrome Extension and select Sandbox Demo, then hit Record Supademo.
Click through every page, dropdown, or feature you want to make accessible.
Stop recording to generate your sandbox demo.
In the editor, open Sandbox Mode and verify/edit the step links.
2. Transform an Existing HTML Demo into a Sandbox
Open any HTML Supademo.
Switch to the </> Edit HTML editor, then select Sandbox Mode.
Add invisible hotspots to elements you want to make interactive.
Repeat across steps until viewers can freely navigate.
