The Neo4j community is launching a challenge to create the best Heroku-hosted demo or template applications for the Neo4j Add-on. Participants will have the freedom to choose their application type, programming language, frameworks, and Neo4j-driver, with the goal of creating educational, tested, and working well applications. The challenge aims to provide valuable feedback for the Neo4j Add-on while showcasing ready-made applications that can be shared in the Gensen Heroku Template Repository. A guest panel will review top applications to identify winners, who will receive prizes including a Neo4j-Heroku t-shirt.
