Railyard is a PaaS that runs on servers you own. Point it at DigitalOcean, Hetzner, or Vultr and push to deploy — managed Postgres/MySQL/Redis, zero-downtime releases, PR previews, canary rollouts, autoscaling. All the Heroku-style workflow, none of the markup — your provider bills you directly, at their price. No lock-in: it's just your own servers, running ordinary containers.
