A shared 2-core box in kvm, running Ubuntu 26.04 LTS. Everything below is read straight from the kernel — no agent, no polling daemon, no database. Just /proc, a Go binary and an open connection.

Capacity is what a normal user can actually reach — ext4 holds back about 5% for root, and this counts that reserve as unavailable.

Memory budget — how to spend 3.82 GiB

planning guide

Base OS ~600 MiB
nginx ~40 MiB
PostgreSQL ~768 MiB
Go services ~1 GiB
Page cache ~768 MiB
Headroom ~500 MiB

The real constraint here is RAM, not CPU. A Go service idles around 15–40 MiB, so a dozen of them fit comfortably. What does not fit: a JVM app, Elasticsearch, more than one database engine, or go build on a huge module while Postgres is under load. Two cores also means a build will use both — expect the dashboard to spike while you compile. That is fine.

New here? Start with the handbook.

Shell access, /srv layout, Go projects, just, how nginx actually routes a request, pointing a domain here, free subdomains forever, TLS, databases, passkey auth, and cheap media hosting on Google Cloud Storage.
