Deploy one representative app to Coolify with a database, secrets, domain, and TLS. Make a safe change, then deliberately ship a broken version and rehearse rollback. Verify logs, backups, and whether data survives application recreation.
A self-hosted platform simplifies deployment only if the underlying server is operated well. Document updates, disk monitoring, key rotation, and recovery from host loss. Compare the full maintenance burden with managed hosting, not just the first deployment.
