I’m looking for another interaction design tool and software that is similiar to Balsamiq Mockups.

The requirements are:

  • The tool is web-based
  • Can be used to create a scratch for application and business intelligence
  • It has a lot of functionality
  • User-friendly
  • Cost/license doesn't matter

My request is to fulfill the requirements above as much as possible.

    Why do you want something different from balsamiq.com ? It's the best mockup software I have seen so far. Commented Apr 7, 2014 at 8:16
  • I understand. I don't know any other recommended mockup tool. Commented Apr 7, 2014 at 11:34

    Could you please answer my question? Why do you want something different? What could be better in balsamiq? If there is nothing that can be better, this question should be closed. If there is something, you should tell us so that we can answer your question! Commented Apr 7, 2014 at 12:34

    I guess web-based is one difference. Pencil can be used as a Firefox add-on, I feel it's almost like web-based so I added it as an answer. I agree that the other requirements are pretty vague. Commented Apr 7, 2014 at 15:03
  • I'm opened minded and there are always other tool to use. I wanna learn new mockup tools. It is the same logic about database. you have oracle, SQL server, Postgre etc. Commented Apr 7, 2014 at 18:26

    After actually going through the effort of using pencil for mockups, I've learned that essence the features are pretty good, but it's really quite buggy. I have to close if every 20 minutes or so and re open it (at least on my mac) to get it to respond again; typically some of the elements become invisible for no good reason!

  • Thanks for the feedback. I have been mostly using Balsamiq mockup under Windows 7, so I don't know how common this issue is. Commented May 2, 2014 at 20:40

You can use moqups:

  • HTML 5 app
  • Vectorial
  • Unlimited team members for all the premium plans

Answer by pixeline

There is another tool, completely free and very promising, built on the Gecko engine (read: Mozilla): Pencil.

UPDATE 3 There is an awesome online prototyping apps comparison chart to help find the right tool for your case.

UPDATE 2 A new tool is available, both mac and windows, and is free (but requires user registration so expect some additional newsletters °-)): indigoStudio

UPDATE 1 Also: Lumzy, which is completely free and boasts a nice list of features.
