German municipalities face vendor lock‑in risk in smart‑city platforms

Municipal officials in Germany are warned that reliance on a single smart‑city platform can create structural dependence. If a provider raises licence fees, drops an interface, or is acquired by a foreign firm, city data on street lighting, tree registries, playgrounds, charging infrastructure and sensor networks could become inaccessible or costly to extract.

The fragmented rollout of digital solutions—each with its own data model and access rights—has produced a patchwork of isolated systems. Exporting data often requires proprietary formats or paid support, new hardware must match the vendor’s ecosystem, and integrating additional services incurs extra project costs. These factors strip municipalities of flexibility, bargaining power and long‑term savings, turning what appears as a technical issue into a financial and strategic concern for local governments.
