A participatory project of Smart City Hameln-Pyrmont
Open Locker The smart locker for everyone.
An open source toolbox for building, sharing, and managing affordable digital locker systems yourself.
What is Open Locker?
In developmentOpen Locker is an open source project for public lockers, including a backend, a mobile app, and hardware blueprints. Our goal is a solution that works reliably in everyday use, adapts to local requirements, and is affordable for those who really need it.
Open Locker builds on controllable costs and open standards: you can run the software yourself or optionally book hosting.
We also build the solution to be easy to use. In the spirit of digital inclusion, our locker is well suited for senior citizens and less digitally experienced groups, too.
From hackathon to open source project:
