What do you like best?
I highly recommend this application to anyone using Salesforce. Skuid is a tremendously powerful UI tool that lets you display your data in ways only limited by your imagination.
The strongest Skuid feature is Skuid's unstopping devotion to add more out of the box functionality that provides an admin or developer with the ability to quickly create interactive Salesforce pages or reports that would have taken orders longer to create with Visualforce.
What do you dislike?
It would be hugely helpful to be able to add comments to any part of your page including, but not limited to, models, UI-only fields, actions, and tables.
Recommendations to others considering the product
You need to try this out. Think of a need you need to meet, and ask Skuid (or me) how easy it is to meet that need. Then, try it out in a developer environment. You will be blown away for weeks on end.
What business problems are you solving with the product? What benefits have you realized?
One of the biggest business problems I've encountered over the years with Salesforce is the problem of data visualization.
Salesforce allows you to create a structured relational database, but lacks the tools to take advantage of those relationships.
With standard reporting, one-to-many relationships are difficult to report on and many-to-many relationships are impossible to report on. With Skuid, I've created reports that can properly aggregate and display as many levels of relationships that I want in Salesforce. And it takes me a couple hours.
On the subject of normalization, another benefit I've realized is page interactivity. Skuid's modern speed and look aside, bringing all of your relational data to one page is enormously beneficial to the user and the developers. The user, for the sake of convenience, and the developer for data control.
