I’m currently working on a freelance Web site redesign project, and in an effort to find a good, easy, cheap, PC-friendly tool for creating site wireframes I came across this great StackOverflow post. I know Mac users are absolutely smitten with OmniGraffle. Until they come up with a Windows version (or I can afford a new Mac), it doesn’t help me out much.

I know MS Visio is another common go-to for this sort of thing, but the few times I’ve used it I was left feeling I should’ve just opened up Photoshop or Illustrator instead.

I checked out the Pencil add-on for Firefox too. After 25+ minutes of trying to get it to do what I wanted it to do without resorting to documentation (I feel a wireframe tool shout be at least vaguely intuitive to someone who uses Photoshop regularly), I shut it down and moved on.

Denim and Balsamiq sounded interesting, but where some people liked that they had a “sketchy” look, I wanted something with cleaner lines that would seem more professional to certain audiences.

Finally, I decided to give Mockingbird a try. And I’m so glad I did.

Mockingbird is in beta right now, and offers free accounts. They’ll probably try to monetize it sometime in the near future with a paid subscription plan. But, for now, its a zero-cost, cloud-based, easy to use platform for quickly, painlessly making a decent wireframe for Web site design. You can create a new project with multiple pages, and then export the whole thing to a zip file containing PNGs of your mock-ups.

I found Mockingbird to be, in a word, perfect. If you’re in need of something easy and convenient the next time you need to pull together a mock-up for a client, I strongly recommend this solution.
