Self-Hosted Automation & Home Lab Wiring

Workflow / iPaaS automation

★ n8n — workflow automation; 500+ integrations; visual editor; great DX. The default for "I want Zapier but self-hosted."
- https://github.com/n8n-io/n8n
★ Activepieces — newer; clean UI; growing fast in 2026.
- https://github.com/activepieces/activepieces
★ Windmill — script-first; TypeScript / Python / Go / Bash; flow editor; very fast.
- https://github.com/windmill-labs/windmill
Node-RED — flow-based programming; great for IoT / Home Assistant glue.
- https://github.com/node-red/node-red
Huginn — older Ruby agent network.
- https://github.com/huginn/huginn
n8n vs. Activepieces vs. Windmill:
- n8n — best integration library, biggest community.
- Activepieces — best UX, friendliest license.
- Windmill — best for code-heavy automation; fastest runtime.

★ Home Assistant — the default; runs on Pi / NUC / Docker; thousands of integrations; mobile apps.
- https://github.com/home-assistant/core
HA OS — Home Assistant's bundled OS for "install on a fresh Pi."
ESPHome — firmware for ESP32 / ESP8266; pairs with HA.
- https://github.com/esphome/esphome
Z2M (Zigbee2MQTT) — Zigbee → MQTT bridge for HA.
- https://github.com/Koenkk/zigbee2mqtt
OpenHAB — Home Assistant alternative; Java; more enterprise-flavored.
- https://github.com/openhab/openhab-core

crontab + scripts — boring, works, you remember why later.
systemd timers — modern alternative; better logging / dependencies.
Healthchecks — see Self-Host Monitoring & Uptime; know when your cron stops running.

For bigger pipelines see Workflow / Pipelines — Argo Workflows, Tekton, Airflow, Prefect, Dagster.

webhook — minimal Go webhook receiver.
- https://github.com/adnanh/webhook
Hookdeck / Svix — see Webhooks.

★ Home Assistant for "make my house smart" + n8n for "make my services talk." Two orthogonal tools.
Idempotent workflows. Don't double-fire actions on retry.
Persistent storage backups. n8n / Activepieces store flows in their DB; back it up.
Don't run unattended automations against destructive APIs. Add a manual confirm step.
Version your flows in git. n8n supports JSON export.
Health checks on critical flows — pair with Healthchecks.
