A Raspberry Pi costs €30 to €80 depending on the model. It fits in your hand. It draws less power than a light bulb. And it can run a ProxyPass node that handles production workloads.
Tested Performance
We have tested a Raspberry Pi 3 streaming four simultaneous Full HD video feeds through the tunnel without dropping frames. The Pi 4 and 5, with their faster processors and better network interfaces, handle even more. The ProxyPass node itself is lightweight — it maintains a single TCP tunnel and processes commands. The heavy lifting is done by whatever application you run alongside it.
Architecture Support
ProxyPass supports all Raspberry Pi generations that matter:
- Pi 2 and Pi 3 — armv7 (32-bit) build
- Pi 3, 4, and 5 — arm64 (64-bit) build for better performance
The install script detects the architecture and pulls the right Docker image automatically. Same command on a Pi 3 and a Pi 5 — it just works.
Scenario: The Smart Agriculture Sensor Network
An agricultural technology company deploys environmental sensors across 60 farms. Each farm has a Raspberry Pi 4 acting as a sensor gateway — collecting temperature, humidity, and soil moisture data from local sensors and forwarding it to the cloud.
They add a ProxyPass node to each Pi. Now they can remotely access every gateway through the tunnel. Check sensor calibration via the local web interface (REST Bridge). Download diagnostic logs (File Mount). SSH into the Pi to debug firmware issues (CONNECT mode). All without driving to the farm, which might be 200 kilometers away.
The Pi runs 24/7 on a €5/year electricity budget. The ProxyPass node uses minimal resources alongside the sensor gateway software. The company manages 60 remote locations from one dashboard.
A Test Platform Too
For IT teams evaluating remote access solutions, the Raspberry Pi is also an excellent test platform. Install a node on a spare Pi, put it on a different network — a friend's house, a mobile hotspot, a coffee shop — and see how it feels to access a device through ProxyPass. The experience is identical to accessing an enterprise server in a data center, because the tunnel does not care what hardware sits at the other end.
If your edge devices run on ARM, ProxyPass runs on them. Same features, same dashboard, same security. No compromises for low-power hardware.
