# Guides

Guides answer a specific question end to end and link into the reference pages for detail. For step-by-step walkthroughs on a live server, see [tutorials](/tutorials/).

- [Coolify vs Levelrail for self-hosters](/guides/coolify-vs-levelrail): how they differ, when each fits, and what Levelrail does not do yet.
- [Self-host Postgres with verified backups](/guides/self-host-postgres-with-backups): create a database, back it up to S3-compatible storage, and rehearse a restore.
- [Zero-downtime deploys without Kubernetes](/guides/zero-downtime-deploys-without-kubernetes): readiness gating, digest-pinned images, rollback, and freeze windows on plain Docker.
