This text discusses the role of civil society in public action to face the consequences of the COVID-19 pandemic in Brazil. Based on a pragmatic approach, the study examines the collective actions promoted by civil society actors in Brazil, highlighting the characteristics, scope, and limits in the governance of this crisis. The study uses documental analysis to observe the recent mobilization of civil society in the country and field research to explore the reality of the city of Florianópolis. The results offer an overview of the performance of “invisible networks” of civil society actors, pointing out the challenges and outcomes of their actions. The findings suggest the need for further studies exploring the role, perspectives, and dilemmas of civil society in the production of “experimentalist governance” in response to the numerous challenges posed by the pandemic at the local level.
