Citizen participation has been fundamental in the design and management of public spaces in Valencia over the last decade, promoting spatial justice. Models such as co-creation through participatory budgeting, self-management and social mobilisation have proven their effectiveness. This article focuses on the study of Valencia’s DecidimVLC digital platform, analysing its influence on participatory budgeting over ten years, since its launch in 2015. The research delves into a participatory project with high media coverage focused on the children’s area of Plaza del Cedro, a neighbourhood park with high community involvement. The results are structured in two sections. On the one hand, a general analysis of the DecidimVLC platform is carried out, examining the types of projects it has promoted. On the other, it provides a specific assessment of the results through the case study of the children’s green area, evaluating the impact of direct interaction with the administration on spatial justice and social cohesion. The study confirms that digital tools such as DecidimVLC are a key vehicle for citizen ‘empowerment’, promoting a more equitable and participatory vision of the city.
