Within the framework of PLUGGY an app challenge will take place in the first semester of 2019 in order to invite external developers to develop pluggable applications for demonstrating the pluggable nature of PLUGGY and its exploitation potential.

PLUGGY as a place for sharing and bringing culture closer to everyone allows developers to create enhanced and non-traditional experience for all the users via exploring content with their applications. As 3rd party developer you can create two types of applications:

  • Plugin integrated within PLUGGY social platform
  • Standalone desktop or mobile or web application connected to PLUGGY back-end

These applications will be available to wide audience and promoted via PLUGGY. Currently, everybody can use PLUGGY’s API but registration process for developers will be opened during the 3rd week of January. Every registered users on PLUGGY social platform ( will be able to apply for developers account that will bring more information and examples how to start development.

For more information about API visit:

Probably the most important document is API specification:

Stay tuned to PLUGGY and have eyes wide open to culture.

Disclaimer: Please keep in mind that PLUGGY is still in development process.

Short Overview of the process

Applicants will prepare an “app description” and send it to The application should be comprised of 1000 words + pictures/graphs + optional video/other data till the end of February 2019.

The app evaluation committee will choose 6 finalists till the end of March, which will receive 1000E each after the completion of the app.

The criteria for the selection are presented below and they fall under the following categories:

  • Integration with the PLUGGY backend
  • Educational potential
  • Commercial potential
  • Social and cultural impact
  • Creativity and innovation


3 months of app development will be provided till the end of June 2019, when the developers will need to submit their app to the committee.

An evaluation of the app for exclusion criteria will take place in July.

Finally, a public competition for the best app through voting, which will take place in September and October will choose the best app, which will receive as price a further 4.000E in a public event organized in Athens in November 2019.

Detailed description of the app challenge will be published on this page, beginning of January 2019.
