The official image uses Redis for the job queue. This template does not use in-memory Redis.

Activepieces if you want Apache-2.0 and a simpler pieces model. n8n if you want the biggest node library — that template is /stacks/n8n-automation.

Stacks / Automation

Easy

Activepieces + Postgres

Apache-2.0 Zapier alternative: Activepieces with Postgres and Redis.

The problem

Zapier and Make meter every run. If you want a fully open-source pieces model instead of n8n's fair-code license, Activepieces is the other box.

Sponsor this stack Tip jar

One-click template from github.com/9o4t/activepieces: official ghcr.io/activepieces/activepieces + Railway Postgres and Redis. Template generates AP_ENCRYPTION_KEY and AP_JWT_SECRET, wires AP_FRONTEND_URL. No operator API keys. n8n is a separate template at /stacks/n8n-automation.

Agent setup prompt

Deploy self-hosted Activepieces that replaces Zapier/Make.

Use the official ghcr.io/activepieces/activepieces image plus Postgres and Redis. Do not combine n8n in this project — that is a separate stack at /stacks/n8n-automation.
- One container, AP_CONTAINER_TYPE=WORKER_AND_APP, AP_PORT=$PORT.
- Set AP_FRONTEND_URL to the Railway public https domain.
- Generate AP_ENCRYPTION_KEY (openssl rand -hex 16) and AP_JWT_SECRET (openssl rand -hex 32). Back them up.
- Wire AP_POSTGRES_URL and AP_REDIS_URL. Health check GET /api/v1/health.
