Purpose: To understand the public value that the website Operação Serenata de Amor [Love Serenade Operation], based on open government data, can generate for society. Originality/value: Researchers are investigating public value generation through digitally transformed public services, i.e., public value directly generated by the government. However, the literature needs a better understanding of this phenomenon through digital technologies, based on open public data, developed by non-governmental actors, such as the Operação Serenata de Amor website. Design/methodology/approach: The study adopted a qualitative approach to understand and describe the public value generated by Operação Serenata de Amor. The data were collected through citizen comments about the website’s initiatives on social media and in articles published on the internet. The data were analyzed through content analysis. Findings: The Operação Serenata de Amor generated public value by doing, facilitating, and stimulating social control. It was also identified that the site added value to society by increasing citizens’ ability to exercise social control. However, this work was limited to analyzing data collected on the internet. In future studies, researchers may collect data through interviews with citizens to understand, with more details, the public value generated by the website.
