10 Free Wireframing and Mockup Tools

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.

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.

Please note that all of these apps have been confirmed as completely free on this articles publishing date.

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 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 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
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
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
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
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.

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
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.
