10 Free Wireframing and Mockup Tools

Finish Design Projects Quickly

The wireframing process is the straight-to-the-point and completely non-tech stage of any web project. It only requires that you define a skeletal outline of essential page elements such as headers, footers, navigation and content area and should illustrate how to cater and respond to any possible interaction from a user.
It is the most important, yet underused, stage of any web or apps development.

Please note that this post is quite old, so some of these apps may not longer be free. Tread with caution.

There are several avenues you could take for sketching a wireframe, most notably pen and paper (the easiest and most cost effective way), but for the sake of this article we have focused on apps that are not only highly effective and easy to use, they are also completely free.

We have covered free wireframe apps before (here), but a year is a long time in web development – some of the apps we had previously covered are either no longer completely free or are no longer available. And as such, we felt that we should compile a new list with more detail and covering all areas of design including web pages, mobile apps and application dev.

As well as showcasing a variety of free apps (11 in total), at the bottom of the post, we have also highlighted some premium wireframing services that do offer free, yet limited, options. You may like to try them.

Lumzy – Quick Mockup Creation and Prototyping Tool

Lumzy - Quick Mockup Creation and Prototyping Tool

With Lumzy, you can create mockups of how your site or application will function by adding events from the extensive list of controls on offer.

As well as having great tools for creating your mockup, you can also create Message Alerts, interactive Page Navigation, add Links to external content, and much more. It does offer a great set collaboration tools for live team editing and a chat engine for deliberating over designs. All of this and it is absolutely FREE.

Mockup Builder – A Killing Prototyping App

Mockup Builder

Mockup Builder has just recenly been released and looks very promising. It is feature-rich and versatile by allowing you create various prototyping styles, including: UI mockups, interactive wireframes, website layouts, desktop software prototypes and even sitemaps & screen navigation.

Of course, it does come with great collaboration tools for sharing with clients and colleagues.

Tiggr – Creating Prototypes Collaboratively

Tiggr - Creating Prototypes Collaboratively

The idea behind Tiggr (currently in beta) is to give you the resources needed to create prototypes (for web, app or mobile) that look and feel like the final product. It allows you to design from a large number of components, share (via email, Twitter or Facebook), you can collaborate with any number of users and will generate an HTML/JS/CSS so that you can preview your UI mockups very quickly. A 10 second registration (email & password) is the only thing you have to go through to use this fantastic FREE tool.

Frame Box – Lightweight Online Tool for Creating Mockups

Frame Box - Lightweight Online Tool for Creating Mockups

Frame Box does not have an extensive list of features (like the web based apps above). You can drag and drop, re-size and copy/paste the UI units, but its main focus, and why we like it so much, is that it allows you to create your mockup/prototype very, very quickly by using its very easy to use drag and drop interface. Again, this app is FREE and only requires a quick registration.

SimpleDiagrams Free Edition (Adobe Air App)

SimpleDiagrams Adobe Air App

SimpleDiagrams (free version) is a tiny Adobe Air app that helps you express your design ideas quickly and simply. Drag & drop symbols from its libraries, add images or post-notes, export as a PNG are all of its features, adding up to just just enough functionality to create a decent mockup.

iPhone Mockup

iPhone Mockup

With iPhone Mockup you have a choice of using either the Pencil styled editor (screenshot above) or the Illustration editor (screenshot below). Whichever editor you decide to use, the functionality remains the same: Its a very simple and easy to use app that allows you to create your own iPhone mockups very quickly, share them with other people at the click of a button, and any changes you make will by synced to everyone who has the mockup’s URL.



fluidIA is a downloadable web based design tool for prototyping rich user interfaces. It allows for rapid refinement and exploration of concepts using an object-oriented approach to design. The original idea behind fluidIA is to discover whether a group of interaction designers, IA’s, UX professionals and developers can create there own prototyping tool in an open way.

Progress on FluidIA has been a little bit slow recently, but the actual app works perfectly for designing a wireframe mockup.

Pencil Project (Firefox Extension)

Pencil Project

Pencil Project is a free and opensource Firefox addon for designing GUI prototypes. With its built-in stencils you can create linked multi-page UI documents and finally export your mockup in either HTML, PNG, Openoffice.org document, Word document or PDF.

What more would you want from a wireframing app? This truly is an essential Firefox extension that any serious developer or designer should use.

CogTool – General Purpose UI Prototyping Tool (Standalone Application for Win & Mac)

CogTool - General Purpose UI Prototyping Tool

CogTool is a FREE and powerful general purpose UI prototyping tool with a difference – it automatically evaluates your design with a predictive human performance model (a “cognitive crash dummy”). You simply create a storyboard of your design idea with sketches, images or on a canvas with CogTool’s widgets, demonstrate tasks on that storyboard, then press a button to produce a valid cognitive model predicting how long it will take a skilled user to complete those tasks.

CogTool offers a lot of support via its extensive user guides, step-by-step tutorials (video and articles), its forum and also offers example files to help you get started.

Prototype Composer (Community Edition)

Software Prototyping - Serena Software

Prototype Composer makes it possible to simulate how an application will look and function before any code is ever written. Instead of endless text entries, complex data hierarchies, or too technical UML diagrams, Serena Prototype Composer makes it easy for business users and business analysts to collaborate on requirements by building simple, high fidelity prototypes that simulate a working application.

It is a tool for prototyping data, processes, activities and most importantly, user interfaces. The application also works as a fairly easy to use Project Management tool.
The Community Edition is its free version which allows users to work in a sample project as well as in one user-defined project.

DUB – DENIM (Standalone Application for Win, Linux & Mac)


DENIM is a free desktop application that is available for Windows, Unix, and Mac OS X. DENIM describes itself as “an Informal Tool For Early Stage Web Site and UI Design”.
It combines many of the benefits of paper-based sketching with existing electronic prototyping tools.

It allows designers to quickly sketch an interface, preserving the important properties of pencil and paper: a rough drawing can be produced quickly and the medium is flexible. However, unlike a paper sketch, this electronic sketch is interactive and can easily be annotated and modified.

Premium Wireframe/Prototype Apps with a Free Option Available

All of the Wireframe & Prototype & Mockup web-based applications below are premium services that do offer a free, yet limited, option. You may like to try them:

    @2640408773c68933d5aa9a6e3b6384ac:disqus Mocking Bird is no longer free, hence the reason you do not see it in this article titled “10 Completely Free Wireframing and Mockup Tools”

  • slapstickj

    Wow, those JustProto people are really spamming this page aren’t they? :)

  • Kartofelek007

    Yep. Very nice list. I check some program from this list. Mockup Builder and Pencil was very nice in use parallel they was veeery slow. In simple prototyping they very good program. But when we create some big layout we cant work on this “turtle-prog” :)

  • Awesome list.Thanks!

  • Hi there, pretty nice tools. You forgot to mention Balsamiq, it’s another online wireframe/mock-up tool but it’s limited and paid for its full features. So I’ll be definitely trying these out.

    Best wishes and thanks for the excellent info.wido

  • iPhone mock-up is a premium feature in Lucidchart, really shouldn’t be in the free list
