Which browsers support JustProto?
The preview of your project will look the same in all modern browsers.
The editing mode is optimized to work with Firefox 3.x, 10.x Opera, Safari 3 or newer, and Chrome. You can use JustProto with Internet Explorer, however JustProto's features can be limited.
We recommend using JustProto in Firefox 3.5+ in order to get the best results.
JustProto works very slowly. Is there any way to make it faster?
We recommend switching to Firefox if you use any other browser. It should make your work much more efficient.
If you already use Firefox - make sure that plug-ins such as Firebug or AdBlock etc. are inactive. They analyze most elements on the page while loading, which significantly slows down the work.
If you think that your work is still to slow – try checking your Internet connection. JustProto is a webbased application and its slow working may indicate there's something wrong with your Internet access.
Can I use JustProto under my own domain?
Yes, this option is available for Plus and Unlimited users. Just add the following to your DNSes:
CNAME chosen-subdomain justproto.com
e.g.
- for the domain your-domain.com
- you would like to use JustProto at the address prototype.your-domain.com
- just add the following record to your DNSes:
CNAME prototype justproto.com
After these steps, write to us at support@justproto.com. Make sure to include your account name and chosen address under your domain. You will receive confirmation as soon as we set it up.
How many people can use my account?
The number of people allowed to edit the prototype depends on your chosen plan:
The Standard Plan – you can work with 3 collaborators.
The Plus Plan – you can work with 12 collaborators.
The Unlimited Plan - you can work with 25 collaborators.
If your business needs are more complex and you have other, more specific requirements, please contact us at support@justproto.com - we will create a plan dedicated especially to you.
JustProto allows you to show your prototype to an unlimited number of people.

Can I use the source code generated by JustProto on my website?
No, JustProto is a tool for creating interactive prototypes, not for creating web pages. Therefore, the code is not suitable for use on websites. Although it guarantees the same look of various elements in different browsers, it does not fit the basic SEO requirements which are so important in designing websites.

Easy, isn't it? We hope you’ll find it useful ;)
Can I create a multi-level structure for my project?
