Keep Portainer, n8n and databases on 127.0.0.1 and reach them through an SSH tunnel, WireGuard or Tailscale instead of opening dashboard ports to everyone.
Claude Code, Codex CLI and OpenClaw on hosted models need no GPU, as the model runs at the provider. See when a GPU matters and how to size RAM and CPU.
Claude Code, Codex CLI or OpenClaw on your own PC or a VPS: what sleep, power at €0.2832 per kWh, security, phone access and plan limits mean, with prices.
What to back up for Claude Code, Codex CLI and OpenClaw on a VPS: repos, settings, memory and OpenClaw state, with logins left out and a restore test.
A VPS reinstall wipes the disk. Save database dumps, Docker volumes, configs, cron jobs, users, SSH and TLS keys and firewall rules, then copy and check them.
Schedule Coolify's database and volume backups with S3 copies, save the APP_KEY and SSH keys they skip, and restore a database, a volume or Coolify itself.

A year at 10% off costs what 10.8 monthly payments cost, so it only pays if you keep the VPS 11 months. Check renewal, refund, setup and upgrade terms too.
