The collaborative prototyping process with Justinmind

With Justinmind prototyping tool, you can supercharge your prototyping process thanks to strong sharing and collaboration features.

In all big enterprises collaboration tools help to boost productivity. Especially when there are designers involved – who often work in distributed groups – and when clients are based all over the world, collaboration management is key.

This is where a collaborative prototyping tool like Justinmind comes in, to make it easier and faster for designers to create together as a team, to get meaningful feedback about their creation, and to share their app or web prototypes with the developers.

Justinmind has always made of sharing and collaboration features one of its strong points, thus enabling an efficient collaborative prototyping process. This post explains how to take full advantage of these features – constantly updated and improved – at each step of the web or app prototyping process.

The Collaborative Prototyping Process

Real-time Collaboration

We will all agree that a team works better when it communicates better. Justinmind helps you in this, optimizing communication and collaboration, and ensuring that everything runs smoothly and within the deadline.

Its teamwork features allow the creation of shared prototypes thanks to Justinmind online service: your team and you will be able to edit and make changes simultaneously on the same web or app prototype. All this can happen in the cloud, or on-premise with Justinmind Enterprise.

You’ll just need to create a Shared Prototype at the beginning of the design process, or share any existing one with other users using the Teamwork drop-down menu. At this point, the project owner will be able to invite (and uninvite) users to edit it. In turn, he can be changed by the owner of the Justinmind account where the project has been uploaded.

All the users have the possibility to lock elements (screens, templates, masters, etc) of the app or web prototype to be the only person with the permission to edit them, so as to avoid conflicts in modifications. Once the work is done, the users can unlock the elements so that others can make all further editing.

When modifying elements of a shared prototype, all the changes are stored locally, until you perform the ‘Commit’ operation and all the changes are uploaded to the server. An “Update” is necessary in order to get all the changes made by other users and be sure that you have the latest version everyone is working on.

And these are only some of the many operations you can perform in a shared prototype environment!

Online and Offline teamwork

With Justinmind you can also open shared projects to work offline: a copy stored locally can be opened at any time to work on it. When a connection is available you will then be able to upload all your local-made changes (“commit”) and sync your project for available updates.

Version control

With big teams working at the same project, it can get difficult to keep track of everything. With Justinmind you can see who did each modification or revision, and create new web or app prototypes from them. All project details and changes are registered for each version.

Share assets with your team

In order to improve teamwork, Justinmind also helps keeping the same design code in the several screens of a single project, as well as throughout other projects the team will be involved in.

The main designers can create the widget libraries following the brand guidelines, and with Justinmind Enterprise they can share them with the team and manage them centrally, so that the entire team is automatically synchronized to the latest version.

The users will only have to drop the objects created by the designer on their canvas, without any confusion of mistaken sizes, colors or deprecated styles. Widgets and templates can be used to maintain the styles, colors, events and structures that are repeated throughout several pages of a single project, or in many different projects, thus enhancing brand consistency. This also contribute to improve productivity, since things don’t need to be redrawn.

Widgets can be treated as independent objects and are easily shareable by mail, network or even personal messaging systems. Most common media types, such as .jpg and .gif, are accepted.


Justinmind generates documentation in several formats: docs for registry and control, HTML for sharing among interested parties and for testing/presentation, CSV for data, etc. This way, your information can always be editable and shareable.

Publish and Share Online

Publish and Share in the cloud with Justinmind


Once your team and you will have the web or app prototype ready, Justinmind lets you publish it on the online platform, where all your projects will be listed, and from where you will be able to share them. As a project owner, you will have complete control over the people who can access and review it.

From your account, you can switch the project to public and allow access to it by sending the URL to anyone you want to see it. If you need extra security, or have confidential projects, you can make them password-protected. Review invites are sent via email to selected users or group of users, and it’s possible to revoke a reviewer’s permission as easily as it is to grant it.

You can make your app or web prototypes available to view in any web browser or device, or publish them on remote user testing tools. Thus, your web or app prototype simulation will always be available for your reviewers to give you feedback. Being able to see the simulation on the actual device will leave small space to mistake when the developing phase will come.

Manage Reviews and Comments

Colleagues and clients can access published prototypes anywhere to test and comment, and they will be able to link their comments to any specific feature or requirement. The comments can then be seen in the specific part of the design that is being reviewed so you’ll never lose track of anything. At each new comment, all the users will be notified with an email.

Feedback System in Justinmind

The comments can be related to any version of the prototype, and they can then be exported and organized in personalized .doc templates, for reports, summaries and analysis.

Furthermore, all feedback can be easily organized in customized categories with labels and colors for solid management, so no details will get lost.

Like with changes, comments and reviews can be made online but also offline. When a connection is available, you will be able to sync your feedback.

When the reviewing phase comes to an end, the web or app prototyping building cycle can re-start, enriched with feedback and comments from all the interested parties. Published projects can be easily replaced with updated versions, and the reviewing part can take place again, as easy as that!

But remember that re-works and changes are not as easy at the development stage as they are at the prototyping stage using Justinmind, so better make the most of it. Try our sharing and collaboration features in your organization and give us your feedback. We listen carefully to our community to learn more about how we can make the product better for you and your team!
