How to Demo a Chrome Extension
August 18, 2026
A browser extension is unusual to demo because it has no interface of its own to speak of. It appears inside other people's pages, which is exactly the thing you cannot control in a screenshot.
The Chrome Web Store listing has its own constraints on top, and they are where most installs are won or lost.
Choose the host site carefully
Your extension will be shown running on some website, and whichever you pick becomes part of your positioning. Demoing on a well-known site implies an association you may not have; demoing on your own site avoids that and can look artificial.
A neutral, widely-recognised category of site usually works best -- and check the terms if you plan to publish screenshots of someone else's product prominently.
Show the install, not just the use
- The Web Store page and the install click, because a surprising number of people have never installed one.
- The permissions prompt. Skipping it looks evasive, and it is the single biggest install objection.
- Pinning the icon, which is where users lose the extension immediately after installing.
- The first real use, on a page where the benefit is obvious.
Permissions are the objection
Extensions ask for alarming-sounding access, and "Read and change all your data on all websites" is genuinely frightening to a non-technical user.
Addressing it inside the demo -- showing the prompt and stating in a caption what you do and do not do with it -- converts better than a paragraph on your website that nobody reaches.
The Web Store listing itself
The listing takes screenshots and a promotional tile rather than an embedded interactive demo, so the demo lives on your own site and the listing links to it. The first screenshot does most of the work, so it should show the extension doing its job, not a logo.
A short video export of the same demo is useful here, since video is a format the listing accepts.
Frequently asked questions
- How do you demo a Chrome extension?
- Show it running on a host website, including the install, the permissions prompt and pinning the icon, then the first real use. The extension has no interface of its own, so the demo is necessarily of someone else's page with your product on top -- choose that site deliberately.
- Should a Chrome extension demo show the permissions prompt?
- Yes. Permissions are the biggest install objection, and skipping the prompt looks evasive. Showing it with a caption stating plainly what you do and do not do with that access converts better than an explanation on your website that few people reach.
- Can you embed an interactive demo in a Chrome Web Store listing?
- No -- listings accept screenshots, a promotional tile and video rather than arbitrary embeds. Host the demo on your own site and link to it, make the first screenshot show the extension actually working, and export a short video from the same recording for the listing.
