for RDS, and suddenly there’s a €200 charge for essentially… not upgrading. That was the moment it clicked for me: Why am I running this in the cloud? I had a spare Raspberry Pi at home. For my use case, I just needed something that runs reliably. So I moved everything to self-hosting. And immediately ran into a different set of problems: Deployments were manual (SSH → pull → restart). Debugging required logging into the machine every time. Monitoring (Prometheus/Grafana) was too heavy for small devices. So I started building a small agent for myself. It began as a deployment tool, but gradually evolved into something more: - deploy apps from GitHub or Docker automatically - self-healing processes with restart logic - system metrics + lightweight monitoring - *heartbeats so I know if a device/service is actually alive* - *log forwarding so I don’t have to SSH in to debug* - reverse tunnels (I use it for Home Assistant instead of Nabu Casa) - remote terminal access from the browser I named it Beacon. It’s open source, and I’ve been running it for the last ~8 months. Everything runs locally on the device (Pi, mini PC, etc.) but there is an optional beaconinfra.dev integration — mainly for monitoring, Home Assistant (or other local app) tunnel, and remote access. I host beaconinfra myself too, and since then I moved away from the Pi to an N100. Repo: https://github.com/Bajusz15/beacon

R. I mean AWS just has to run it in a different environment. For 200 I could buy them a new server to run it for me. I thought to myself, I have a spare Raspberry Pi 3, I will just host it on that. Then my journey on self hosting started, I decided to cut ties with AWS or any cloud provider. I faced many challenges, particularly due to resource constraints with the tiny 1GB ram and slow storage. Then to solve my own problems I made Beacon, and I'm sharing it now to help others who face similar challenges. Beacon solves a problem for self-hosters (or if you host on bare metal), IoT homelab users. It's an open-source agent that makes it easy to deploy apps and monitor devices (like Raspberry Pi) without the overhead of traditional tooling. Forget bloated stacks like Jenkins, Opensearch, Grafana, or Datadog. Beacon is a single ~15 MB Go binary that: * Automatically deploys new releases from Git tags * Monitors endpoints, ports, and system metrics with custom commands * Forwards logs from files, Docker, and commands Note: Beacon is currently in Beta development — APIs, configs, and features may change as it evolves.
