Konstrukt vs UI-O-Matic
Differences between Konstrukt and UI-O-Matic, the back office UI builders for Umbraco.
For anyone familiar with Umbraco you may already know of the open source back office UI builder, UI-O-Matic and be wondering why you should choose Kostrukt instead. To help with that decision, we've put together the following feature matrix to compare some of their major differences.

Seperation of Concerns
Yes - Config is seperate to poco models

Manage 3rd Party Models
Yes - As config is seperate to poco models, Konstrukt can manage any poco models
No - As config is attribute based, you need to have full control of poco models to add attributes to

Config is always in the context of the poco model with Konstrukt automatically converting between properties and DB columns
Config switches between poco model properties and DB columns so can be confusing if you aren't aware of the context
