To help you out, we will introduce 12 of the best free prototyping tools in 2020, including their pros and cons, prices, and compatible platforms, for you and your team to choose the perfect prototyping tool with ease.

First, how to choose the right prototyping tool?

Before getting started to evaluate prototyping tools on the market one by one, you should firstly know how to choose the right prototyping tool.

Here are key factors that you should consider while choosing a UX/UI prototyping tool:

1. Figure out what you or your team need

Which tool you will finally choose often depends on what you or your team really need. So, the first thing for you now is to figure out your purpose for choosing a prototyping tool.

For example, if you merely want to draw out your design ideas and iterate on your own, you only need a free prototyping tool with simple UI elements and basic prototyping features.

But, if you want to make a high-fidelity prototype to test your final product and iterate with your whole team, a high-fidelity prototyping tool with a powerful collaboration feature is exactly what you need.

So, before checking different prototyping tools on the market, it is better for you to make a list of all your or your team’s needs.

2. What key features will it offer?

While choosing from various prototyping tools, you should remember to check their key features carefully based on your requirement list. If one or two of them can meet your needs perfectly, it would be great. If not, also don’t be sad. You still have other factors to consider yet.

3. Will you need to collaborate with your team?

Team collaboration is essential for product teams to create a brilliant web/app prototype these days. So, while choosing a prototyping tool, you should also check whether it supports team collaboration and management.

A good prototyping tool often makes it easy to share a project and get feedback quickly. Any changes about the projects sometimes will also be synced to the whole team instantly.

4. How long will it take to learn and use the tool?

The learning curve of a prototyping tool also matters. A tool with an easier learning curve is a better choice for you and your team to get started quickly.

So, before making a decision, it is best for you to download and give the tool a try for checking its learning curve.

5. How much will it cost?

The cost is the most important factor you should take into consideration. No matter whether you will choose a monthly, yearly or perpetual payment plan, the tool that suits your best is the right one for you. You should always compare prices of different tools and never be blinded by their features or prices.

6. Does it provide instant after-sale service?

While using a prototyping tool, it is quite possible to encounter some usage problems or bugs. These days, the after-sale support becomes very important. So, before making a decision, you should consult about the after-sale support service clearly.

Overall, we hope these main factors will help you choose a perfect prototyping tool quickly.

Every web designer and developer should have a good and reliable wireframe (mockup or prototype) tool at there disposal. The importance of such a tool differentiates amongst web designers and developers, some use them, some don’t. Personally, I use them. It is in this initial stage of development that makes web design enjoyable, the coming together of the clients needs and your own creative ideas onto a blank canvas, allowing you to plan effectively the visual arrangement of the sites content.

The downside is that a good and reliable wireframe application can come at a heavy price, have you seen the cost of a good wireframe application? Prices can vary from as low as $100 all the way up to over $4000. Who has this kind of mine to throw around? Certainly no freelancer developer I know.

So, what options do you have? There are certainly a fair few free web apps and tools you can use, and that is what I have collated for this article – The Ten Best FREE Wirefame/Mockup/Prototype applications for designers and developers.

Hot Gloo – The Online Wireframe App

The first thing you need to know about Hot Gloo is that it is in Beta, the second thing you need to know is that it is currently free, but with plans to charge a fee later on this year, so, grab your chance now while its free, its worth it.

HotGloo is an easy to use and intuitive Flash built web-based wireframe app, that can create conceptual interactive prototypes of a website in the early development stages.
Features include drag and drop facilities, layers, grid and snap to grid, a fair rew preset elements, interaction between the elements and you get your own custom HotGloo URL that allow you to share your mockup/wireframe with your clients.

Pencil Project

The popular and fairly powerful Pencil Project is a free and opensource Firefox addon tool for making diagrams and GUI prototyping with a multitude of features.
With its built-in stencils for diagramming and prototyping, the option for multi-page documents with background pages, its on-screen text editing with rich-text support and with its new capability of exporting to HTML, PNG or Openoffice formats, makes this addon essential for any developer or designer.

Web Site Wireframe Tool

The key to this tool is the simplicity of usage, lending itself to speed, both in wireframe creation, as well as being able to quickly share the results without having to send anything more than a web address.

This particular tool allows the wireframe to be built in minutes, and if desired, a link to view the wireframe can be sent through email, instant message, or even the phone. With both parties able to view the wireframe even from different locations, the wireframe can then easily be updated based on feedback, discussion, ideas, suggestions, and so on.
It is free to register and use, and works in modern web browsers including Internet Explorer and Mozilla Firefox.

DUB – DENIM

DENIM is a free desktop application that is available for Windows, Unix, and Mac OS X. It describes itself well as 'an Informal Tool For Early Stage Web Site and UI Design'.

It is an outgrowth of the original SILK project, a pen-based sketching tool for designing user interfaces. SILK combines many of the benefits of paper-based sketching with existing electronic prototyping tools. It allows designers to quickly sketch an interface using an electronic pad and stylus. SILK preserves 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 using editing gestures. SILK allows the designer to extend the interactivity of the recognized widgets using storyboards

Mockingbird

Mockingbird is an online tool that makes it very easy for you to create, link together, preview, and share mockups of your website or application.

With its clean and clear interface, drag and drop functions, snap-to-grid, unlimited page linking and pretty much all the UI elements you could ever need, it all adss up to making Mockingbird our favorite wireframe app on this page.

MockFlow

Let me start by saying that MockFlow is not entirely free, there is a free package (limited to 1 Mockup with 4 pages and 10MB of storage) which, to be honest, really isn't much use to anyone. The premium yearly package costs $49 (reasonable price), which gives you unlimited mockups, unlimited collaborators, 500MB of storage and, most importantly it gives you access to the marvelous Mockstore.

MockFlow gives you everything you would expect from an online wireframe app, with one added bonus – its Mockstore. This is a large library of templates and presets that you can freely use (with the premium package) and will help speed up your workflow and give some added professionalism to your wireframe.

It is a tool for prototyping data, processes, activities and most importantly, user interfaces. The app also works as a Project Management tool, which is fairly simple to use, but a little bit too much for what I need, making this application more suited for a larger company.

fluidIA

FluidIA is an emerging agile design tool for prototyping rich user interfaces. This web based tool allows for rapid refinement and exploration of concepts using an object-oriented approach to design.

The big idea behind this experiment is whether a group of interaction designers, IA’s, UX professionals and developers can create there own prototyping tool in an open way. They have almost succeeded. FluidIA is still a little bit buggy, but looks very promising.

Cacoo

Free Prototyping Tools Machines

Cacoo is a user friendly online drawing tool that allows you to create a variety of diagrams such as site maps, wire frames, UML and network charts.

Lumzy

With Lumzy, you can create prototypes of how the site or application will function by adding events within your Lumzy controls. For instance, what happens when the user clicks a button?

With Lumzy, you can easily create your mockups and send to clients on the fly. It also features collaboration tools for team editing, a chat engine for deliberating over designs, file versioning and so much more.
