## Documentation

# Deploy and Host Windmill on Railway

Windmill is an open-source developer platform for turning scripts (Python, TypeScript, Go, Bash, SQL and more) into webhooks, workflows, cron jobs and internal apps with auto-generated UIs. This template runs the Windmill server, a default worker and a PostgreSQL database with a persistent volume, so your scripts, flows, schedules and run history survive redeploys.

## About Hosting Windmill

This template deploys three services from the official `ghcr.io/windmill-labs/windmill` image (pinned by digest) plus `postgres:18`. The server (`MODE=server`) serves the UI and API on the public domain. A separate worker service (`MODE=worker`, group `default`) executes jobs, so you can scale workers independently. Both connect to PostgreSQL over Railway's private network; the database password is generated at deploy as a random secret and shared with the app services by reference, so there is nothing to type. PostgreSQL stores its data on a volume mounted at `/var/lib/postgresql`. After deploy, open the public domain and sign in with the Windmill default account (`admin@windmill.dev` / `changeme`); Windmill asks you to set a new password and create your first workspace right away, so do this immediately after the first deploy.

## Why Deploy Windmill on Railway

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Windmill on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.

- **Server, worker and database wired together** — no connection strings to assemble.
- **State survives redeploys** — Postgres sits on a volume, not on ephemeral disk.
- **Scale workers on their own** — add replicas of the worker service when job volume grows.
- **No per-execution SaaS fees** — run as many jobs as your instance handles.

## Common Use Cases

- **Internal tools** — build admin panels and approval apps on top of scripts.
- **Workflow automation** — chain scripts into flows with retries, branching and schedules.
- **Webhooks and cron** — expose any script as an endpoint or run it on a schedule.

## Dependencies for Windmill Hosting
