We model deterministic container memory requirements on StackPilot so solo builders can verify 6 operational prerequisites — SSH hardening, localhost port binding, 25% RAM headroom, auto-TLS, and 3-2-1 backups — before replacing recurring SaaS subscriptions.
Short pre-check note: tick off each StackPilot readiness step below to save progress locally in your browser.
Select the self-hosted services you plan to co-locate. Our StackPilot formula sums documented container RAM/storage footprints against 5 public hosting tiers.
KVM 4 (4 vCPU • 16GB RAM • 200GB NVMe) • $10.49/mo
Consolidate Docker, n8n, Coolify, and Uptime Kuma on one AMD EPYC KVM node sized from official container specs.
Tick each verification item as you configure your server; progress is persisted locally in browser storage with zero server-side tracking.
Before starting Docker Engine on a 4 GB or 8 GB KVM slice, verify PasswordAuthentication no inside /etc/ssh/sshd_config and restrict port 22 or custom SSH port via UFW so automated brute-force scanners cannot saturate auth logs.
Docker manipulates iptables directly and can bypass UFW if you publish 0.0.0.0:5432. Bind internal Postgres/Redis ports to 127.0.0.1:5432 and expose only TCP 80/443 through Caddy or Traefik.
We calculate minimum RAM from documented container footprints plus 25% Linux page-cache headroom (e.g., n8n 2 GB + Coolify 3 GB + Immich 4 GB + Kuma 1 GB = 10 GB target on a 16 GB KVM 4 node).
Create clean A/AAAA records (flows, git, photos) with 300s DNS TTL so Caddy or LiteSpeed renews TLS certificates automatically every 60 days without manual cron scripts.
Run pg_dump / mysqldump before restic or borg nightly snapshots to an off-node storage target and test a full restore into a temporary directory before migrating live team data.
Keep webhook dual-delivery or read-only SaaS access active for 48 hours, verify Uptime Kuma alerts on HTTP 200 checks, and only then turn off recurring SaaS auto-renewal.
Preview how StackPilot models n8n, Coolify, Plausible, and Vaultwarden memory overhead (~8 GB DDR5 RAM) with Caddy auto-TLS before migrating production data.
We compile baseline specifications and official vendor pricing URLs retrieved on 2026-11-12 so readers can audit promotional and renewal terms directly.

All 8 StackPilot workload blueprints and 5 SaaS-to-VPS TCO breakdowns remain accessible below for reference.
Replace $49/mo Zapier task caps with an unlimited self-hosted n8n + Redis worker stack using Hostinger 1-Click OS templates or Docker Compose.
Turn one $5.99–$10.49 NVMe VPS into your private Vercel + Railway + Supabase alternative with preview PR URLs, managed Postgres, and zero bandwidth overages.
Host a ChatGPT-grade workspace for your entire team with local Llama/Qwen models on UltaHost Dedicated RAM VDS or pay-per-token API routing.
Own every RAW photo and 4K family/creator video with iOS & Android background backup on InterServer’s $6/mo 1TB Price-Lock Storage VPS.
Ship production AI customer bots, RAG pipelines, and visual LLM workflows without hitting SaaS vector document caps on Hostinger KVM 4 or UltaHost VDS.
Escape Substack’s 10% revenue cut and Ghost Pro subscriber-tier price hikes by running Ghost 5 + MySQL 8 on a fast NVMe VPS.
Want self-hosted ownership without touching Docker or SSH? Launch sub-200ms TTFB WordPress/WooCommerce on ChemiCloud Singapore/Tokyo LiteSpeed nodes.
Monitor 100+ endpoints every 20 seconds with Discord/Slack alerts and cookie-free lightweight web analytics on one shared indie observability VPS.
Yes! Lightweight Docker apps like n8n, Coolify, Ghost, and Uptime Kuma mostly idle between requests. An 8GB–16GB NVMe KVM VPS (like Hostinger KVM 2 or KVM 4) easily runs 4–6 containerized tools simultaneously with automatic daily backups.
You have two effortless paths: use Hostinger’s 1-Click Application Templates (which pre-install n8n, Coolify, or Docker via a web dashboard) or choose ChemiCloud Managed LiteSpeed NVMe ($2.95/mo) for zero-CLI WordPress, WooCommerce, and newsletters.
InterServer locks your exact monthly rate for life ($6/mo per 1TB Storage VPS with zero renewal hikes), while Hostinger lets you lock up to 24–48 months upfront with an extra 20% partner discount.
Our planner inspects your checked workloads: Docker & automation bundles map to Hostinger 1-Click KVM NVMe, heavy 1TB+ photo/file vaults map to InterServer Price-Lock Storage, zero-CLI sites map to ChemiCloud LiteSpeed, and private local LLMs map to UltaHost Dedicated RAM VDS or Vultr Cloud GPU.
