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, iOS, and Android (as closed beta). 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.[1] 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. Version 1.3 introduced new features that allow you to add your own actions and elements and create more individual applications.

Design Goals[edit]

Protogrid on multiple platforms

According to the web site of the developers[2] 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


Names can be defined in multiple languages


Protogrid applications are supposed to be portable to all Protogrid clients without additional programming effort.

Touch screen optimization[edit]

Protogrid applications are optimized for touch screens.

Support for Responsive Design[edit]

Protogrid applications run on a range of screens starting from smartphones, tablets unto large screens. The fields and columns are automatically distributed.

Cloud based[edit]
