Alteryx One is a single platform designed to bring together analytics, automation and AI. It includes multiple tools/features which encompass many aspects of the data analytics process. For an organization, having everything in one location simplifies the management of users and is more intuitive for businesses to work with.
Alteryx One offers different licensing structures, giving users different functionality - the ideal license depends on the requirements of the user.
App Builder
App Builder is a ‘no code’ tool that enables users to run and interact with workflows via a web application. The idea behind them is similar to apps in Alteryx Designer but they do differ in certain ways. Firstly, there is more design freedom within Alteryx One with how the output app looks and feels. However, there is less flexibility with editing/building workflows (but you can still perform simple data transformations/manipulations such as aggregations, filters and functions).
The interface of App Builder is certainly more sleek looking and easier to navigate than Alteryx Designer...
Under the orchestrate pane you have the options to add in workflow tools, charts, buttons etc. which will form the groundwork of your app. The design pane is where you can arrange all the elements and change the general aesthetics of the app such as color, font and sizing of elements.
Once all the configuration and aesthetics are done it is simply a case of publishing and interacting with the finished app!
