What is Open Locker?

In development

Open Locker is an open-source project for public locker systems, including a backend, a mobile app, and open hardware designs. Our goal is a reliable and affordable solution that can adapt to local requirements.

Open Locker focuses on predictable costs and open standards: you can run the software yourself or use our optional managed hosting.

We are also designing the system to be easy to use. To support digital inclusion, it should work well for older adults and people with less digital experience.

From hackathon to open source project:

Our background story

Features at a glance

Easy to build

Affordable

Easy to use

Retrofittable

Self-hosting

Prefer managed hosting?

If you don't want to operate Open Locker yourself, we can host the central backend for you in Germany using renewable energy. This reduces your operational workload and directly supports the project's continued development.
