Your Homelab Is Where the Fun Starts
Your side project starts on the free tier. Then it gets interesting. This week, Tod from Catalyst Community joins us to talk about why the homelab is one of the best places to build open-source software, experiment with AI, and learn the infrastructure underneath the tools we use every day. We get into why Kubernetes does not need to turn you into a Kubernetes administrator, how Foundry is making it easier to stand up K3s on your own hardware, and why tools like Helm make adding databases, monitoring, storage, and other services much less painful once the foundation exists. Tod walks us through his own homelab: Proxmox, Debian, a three-node Kubernetes cluster, separate storage and GPU machines, and the open-source tooling he uses to build on top of it. We also get into Tailscale, KServe, Ray, CloudNativePG, Prometheus, Grafana, Loki, Whisper, and running GPUs both inside and outside Kubernetes. But the bigger conversation is about building. Matt talks about the GPU machine he originally bought to train a StarCraft bot and how that experimentation turned into skills he could use professionally. Miriah talks about replacing a Supabase free-tier database with Postgres on her homelab. Tod talks about replacing GitHub-hosted CI/CD infrastructure with his own open-source system. The common thread: doing the foundational work once gives you a platform where the next idea is much cheaper to try. And with modern hardware, open-source software, and LLM-assisted development, the barrier to building something useful at home has never been lower. So our question for you: What are you building for yourself, for fun, or for open source? Projects mentioned in the episode include Foundry, K3s, Kubernetes, Helm, Proxmox, Tailscale, KServe, Ray, CloudNativePG, Prometheus, Grafana, Loki, MLflow, Whisper, Render, Supabase, and Anthropic Claude. Keep your AI on a leash.
