I got an beta invite to creately. I have to say i quite like it. It definitely goes in the right direction.
It is, as i said still in beta mode. And when i compare it to Axure Pro, which is a desktop app, it’s still lacking features.
Creately is not only for wireframing like Axure Pro is, it is also for all kinds of flow charts and diagrams. I hope that they really further optimize the wireframing aspect of creately. There are quite a lot of tools missing when you compare it to Axure.
Here is a fake wireframe i created in like 5 mins. just as a test in creately:
What i really really like about creately are the sharing options. You can publish your wireframe to a create.ly url within a second. Here is the URL to mine:
Also another highlight are going to be the collaboration options. That’s what i really need most for my kind of work. I need to be able to share my wireframes quickly with my team and have them adapt them if needed. So looking forward
