Knack helps non-programmers easily build beautiful, data-driven web apps. Data can be imported from spreadsheets and converted to an online database. Tools like search, forms, and tables are used to builder web apps that work with the data. Apps can be published to any site and adapt to the surrounding design.
Clean, quick and powerful. A good template library of projects to kickoff from and a comprehensive API.Cons:
Some of the functionality around setting up conditions and validations isn't intuitive. Same for importing data models from a csv.
I love this product. It markets itself as online database software, and surely could be used for that, but in my case I find it incredibly useful as a prototyping platform. If you have a web app concept that needs quick validation and are finding mockups and wireframes insufficient, Knack could be a huge timesaver, and a lot easier to setup and run with compared to getting the same functionality (without styling) out of Adobe products, Moqups or Sketch. A wysiwig for MVC-based web apps.Scott Kipp has used this product for one week.
