Citizen engagement in urban planning is essential to designing urban spaces that are just and responsive to societal challenges. Consequently, local stakeholders are invited into urban co-creation processes. Digital tools are often used in this process to shape urban futures together. This paper explores what role digital technologies play in urban co-creation through five case studies from European cities that were presented at a workshop during the 11th Communities and Technologies conference. The Co-Design Framework is used to analyse the cases and understand how digital tools support collaboration on different levels throughout the design cycle. The findings help to design more effective digital tools for urban co-creation and provide an analysis methodology to compare and contrast urban co-creation practices across cases varying in scale, time, and utilised tools.@en
