The best free online wireframing and prototyping tools

Wireframes and prototypes are one of the most popular ways of communicating between team members or other stakeholders. Whatever is your role in the process of creating a digital product, you can use those methods to quickly visualise your ideas. But not always there’s an Axure or Visio license around and sometimes paper sketches are just not convenient enough to use remotely. How about some free online wireframing tools you can use in your browser and not worry about licenses or scanning sketches?


With InVision you can quickly turn your designs into interactive prototypes. The tools is focused on easy collaboration and getting feedback on your designs, whether from team members or from your respondents. Tons of great feeatures, including importing .psd, .ai. or .sketch files and integration with Dropbox, Basecamp, Trello, Slack, Flowdock or HipChat.

Almost free

When thinking of a tool you will use in your everyday work, an expense of 10-30$ doesn’t sound excessive. That’s why you might want to look at paid tools such as, UXPin or Cacoo. Better keep an eye on UXPin, which has been gaining more and more traction recently, becoming a serious Axure alternative. Constantly upgraded, packed with features and reliable is what you can get for as little as $15/month. Of course the three paid tools I mentioned above allow you to test them for at least 15 days.

Now don’t waste your time! Go and design awesome interfaces!
