Protogrid is an integrated application development solution for the development and operations of information systems. It comprises a server and a client. The client is available for web browsers and iOS. Protogrid includes a development interface that allows for development of applications using rapid application development methods. On the back end there are NoSQL databases like CouchDB. Business logic can be added to a Protogrid application using Javascript. With version 1.1 which was released in May 2016 a json API providing external access was introduced.
According to the web site of the developers the goals were
rapid application development: avoid the programming of standard stuff like table views, standard action buttons, menus etc.
cross platform development: any Protogrid application runs as it is on all platforms supported by Protogrid (at present: several web browsers and iOS)
multi language support: any Protogrid application can be translated within hours to any other language by a person with knowledge of the source and target language
ability to run off-line: any Protogrid application must be able to run off-line on a mobile device offering the full set of functionality
Portability: Protogrid applications are supposed to be portable to all Protogrid clients without additional programming effort.
Touch screen optimization: Protogrid applications are optimized for touch screens
Support for Responsive Design: Protogrid applications run on a range of screens starting from smartphones, tablets unto large screens. The fields and columns are automatically distributed.
Cloud based: The Protogrid back end server resides in a public or private cloud¨
Web enabled apps: Any Protogrid application runs in a browser as web app
Multi language support: As well Protogrid as Protogrid application allows for multi language support
Support for off-line operations: A Protogrid application runs also without internet access. Data is synchronized automatically as soon as internet connection is available.
Data types supported: Text, Date with time, Number, Relations and Tables referencing other records.
JSON API: an API is provided that gives read and write access.
Additional features are intended to be implemented in the near future. This includes the support for Android and a native desktop client as well as client-side Javascript ScriptLibraries and diagrams that provide an overview over the data.
