A compact host for automation, observation, and an LLM agent.

AI Tools is a purpose-built Docker host. Caddy publishes HTTPS; each app is its own Compose stack on a private proxy network. Small on purpose, so every new service has to earn its RAM.

Compute 2 vCPU · 4 GB cx23, 40 GB disk

Edge Caddy on 80/443 Let’s Encrypt, gzip

Shape One stack, one project Apps join proxy

Deployed

Three tools, one public info page.

Each hostname is a purpose, not a product name. They share the host, not a Compose file.

Live flows.zolvek.net

Flows

n8n workflow automation. Connect APIs, webhooks, and schedules without putting another runtime on the box.

Open flows

Live monitor.zolvek.net

Monitor

Beszel hub and agent. Host CPU, RAM, disk, and per-container usage so the 4 GB budget stays visible.

Live agent.zolvek.net

Agent

Hermes Agent dashboard. An LLM agent with memory, skills, and a capped memory limit so it cannot starve the rest of the host.

Open agent

Platform

Built as a control plane, not a pile of containers.

Git is the source of truth. Stacks sync to /opt independently. Public HTTPS exists only through Caddy; apps expose ports on the Docker network and never publish 80 or 443 themselves.

Location Hetzner Cloud, Falkenstein (fsn1), Ubuntu LTS.
Network Domain zolvek.net. A and AAAA records, TLS at the edge.
Isolation One Compose project per app. Named volumes hold runtime state; they are never torn down casually.
Authoring Reusable Python, n8n workflow exports, and Hermes skills live beside the stacks, not only on the server.

Potential

Headroom for more purpose-named tools.

The host is already wired for another stack: add Compose, a Caddy site block, DNS, and a light container. Monitoring is in place before the next service arrives.

Automation that compounds

n8n can grow into a library of versioned workflows: alerts from Beszel, webhook receivers, reports, and glue between APIs — without a second application server.

An agent with a job

Hermes can take provider keys, skills, and longer sessions. The dashboard is already public; the memory cap keeps it a neighbor, not a tenant that fills the machine.

More small sites

This page is nginx on 32 MB. Status pages, internal docs, and landing URLs fit the same pattern: static files, Caddy, a purpose subdomain.

A known budget

4 GB is the constraint and the design. New work stays lightweight, observed, and independently deployable — or it does not ship here.
