Secure Prototype Hosting



At a Glance

Secure prototype hosting allows customers to upload an HTML prototype that is hosted by UserTesting. The prototype is only accessible by test participants during the time of testing, adding an extra layer of security to your top secret designs.

How It Works

Exporting Framer Prototypes



Key features

  • Participants can only access prototypes after they’ve been approved for the study.
  • Study participants can’t access the prototype after their session has ended or copy or share the URL.
  • Customers may access their own uploaded prototypes, however, they will not be able to share the URL with anyone outside fellow team members on the account, ensuring privacy and security.

How It Works

Step 1: Upload your HTML file

After logging into your account and creating a new prototype study, select Upload HTML .zip file.

Secure prototype hosting requires the upload of the prototype (HTML file) via a .ZIP file. You will not be able to use this feature if the third-party prototyping tool you are using does not allow the downloading of the prototype into this file type. The contents must include a valid index.html along with all of the required elements of your prototype.

Step 2: Customize your link

Once you’ve uploaded your zip file, you can direct participants to a specific page of your prototype by navigating through the custom-generated, secure link. Once you’re at the page of your prototype that you’d like participants to begin their session, simply copy that URL and paste as the Starting URL for uploaded HTML.


Step 3: Complete and launch your study

Once your secure prototype link has been generated, proceed with completing and launching your study as usual.

Exporting Invision prototypes

You can export your Invision prototype by selecting Download Prototype in the drop-down menu for your prototype.

When prompted, select to generate a zip file. Once you have the file, you can upload it and use it in your study.

Exporting Axure prototypes

Axure provides the ability to export HTML that can then be used with prototype hosting. From the publish menu, select Generate HTML Files…


Next, create a zip file from your exported HTML. To create a zip file, right-click on the folder with your generated HTML and select Send to > Compressed (zipped) folder (Windows) or Compress… (Mac). You can then upload the zip file to use with your study.

Exporting Framer prototypes

Framer prototypes just need to be zipped in order to be uploaded for prototype hosting. To create a zip file, right-click on the Framer file and select Send to > Compressed (zipped) folder (Windows) or Compress… (Mac).



The hosted assets are encrypted at rest and only accessed through SSL. These are kept securely in our AWS infrastructure and only accessible through secure links that are inactive unless the test is in progress and used by the assigned active tester.
