Documentation

How Hetscale works, how a node gets your application, and what every setting does. The decisions behind it are recorded as architecture decision records in the application repository; the docs link to them and never copy them.

Start

Quickstart
From a Hetzner project to a scaling group in four steps: connect read-only, read the day-0 report, run one Rehearsal, go Live with a floor of two nodes.
Concepts
The words Hetscale uses: node, node group, seed, release, adapter, traffic provider, readiness, drain, ownership labels, and the four modes.
Modes
Observe, Rehearsal, Propose and Live: what each mode may do, how to switch, and the inputs and defaults every decision uses regardless of mode.
