Make Yourself an Onion SaaS, or Applied 'Onionery' in IT Projects
summary
A practical guide to building a low-cost SaaS MVP by combining free-tier/cloud services, cheap VPS or homelab hardware, open-source components and no‑/low‑code connectors. The case study shows prototyping a neighborhood-reporting app using Docker, Postgres/Supabase or SQLite, Cloudflare R2 for files, GitHub Actions CI, deployments to Vercel/Netlify or a €5 VPS, Certbot for TLS, Restic backups and Uptime Kuma/Grafana monitoring. It also reports operational lessons: exposed servers attract thousands of scans and unpredictable cloud bills, and a small VPS is often the best trade-off.
