Managed (Vercel, Fly, Render, Railway, Cloudflare, Netlify), open-source self-hosted (Coolify, Dokploy, Caprover, Easypanel), and roll-your-own on a VPS (Kamal 2). This piece compares 14 platforms in one sitting — Fluid Compute, multi-region, Git-driven deploys, preview environments, cold starts, the return to your own servers — and ends with who should pick what.
