Case Study: Rotterdam.nl achieves delivery of 100+ low-code applications to digitize city services with Mendix

The City of Rotterdam Empowers Development at Scale

The City of Rotterdam, serving about 660,000 residents, was struggling with rising citizen expectations for digital services, strict data-privacy constraints, an 800‑system IT landscape and a growing backlog caused by siloed business and IT teams that led to slow, expensive projects and shadow IT.

Rotterdam adopted Mendix low-code and formed an agile Rapid Application Development (RAD) team, standardized processes, reusable modules and a citizen‑developer program to scale delivery. In under four years they built 100+ apps—from internal process tools to public services—cutting delivery times and backlog, enabling rapid COVID response (a Digital Counter built in weeks), launching REP parking (MVP in 8 weeks; serves millions of visitors) and trashR (≈€80K annual savings), while improving transparency and citizen engagement.
