I self-host my SaaS on three mini PCs for $11/month. Here's the full setup.

SayThat.sh runs on three Intel i5-10500T mini PCs sitting under my desk. No AWS. No Vercel. No monthly cloud bill. The entire production infrastructure - database, cache, API, frontend, monitoring, analytics, CI/CD - runs on hardware I own, for about $11 per month in electricity. This is how it's set up and why I went this route. The hardware Node CPU RAM Storage Role st-cp-01 i5-10500T (6c/12t) 24 GB 2TB NVMe SSD Control plane + builds st-cp-02 i5-10500T (6c/12t) 16 GB 256GB NVMe SSD Control plane st-cp-03 i5-10500T (6c/12t) 16 GB 256GB NVMe SSD Control plane Three machines, 36 cores, 56 GB RAM total. Each one cost somewhere between $120 and $250 used. All three are k3s control-plane nodes running embedded etcd for HA consensus. There is no separate worker tier - every node participates in both cluster management and workload scheduling. The software stack Orchestration: k3s with embedded etcd - any node can go down and the cluster keeps running. Database: CloudNativePG operator manag
