Why I Chose Coolify to Self-Host Everything

I run multiple production applications — a multilingual B2B platform, a DeFi frontend, a personal site, internal tools. At some point I had to make a decision: pay for managed hosting and let someone else handle the infrastructure, or own the server and own the problem. I chose the server. And then I chose Coolify to run it. Here's why. ## What Coolify Is Coolify is an open-source, self-hosted platform that gives you the deployment experience of Heroku or Railway — without the bill and without handing control to someone else. If you want the managed version without the ops overhead, they also offer Coolify Cloud. You bring a server. Coolify gives you: - One-click Docker deployments from a Git repo - Automatic SSL via Let's Encrypt - Reverse proxy (Traefik) configured automatically - Environment variable management per service - Database provisioning (MySQL, PostgreSQL, Redis, and more) - A clean web UI to manage all of it It's the ops layer I'd have had to build myself otherwise. ## Why Not Just Use Railway or Render I've used managed platforms before. They're genuinely good for getting started. But they come with a ceiling. The first thing you hit is cost. A few always-on services, a couple of databases, some background workers — the bill climbs fast. What looks like $20/month in the docs turns into $120 when your actual workload lands on it. The second thing is control. Managed platforms abstract the server, which is convenient until it isn't. Debugging a performance issue, tuning a database config, changing how logs are retained, setting up a custom proxy rule — these things require access that managed platforms don't give you. For SharMarket, I needed fine-grained control over how services talked to each other, where data lived, and how the whole system behaved under load. I wasn't going to get that on a platform that hides the server from me. ## The Cost Reality A mid-range Hetzner dedicated server — the kind that would handle everything I run — costs a fraction of what the same workload would cost on Railway or Render per month. That gap only grows as you add services. With Coolify, every additional app is just another deployment on the same server. With managed platforms, every app is a new line on the invoice. For a startup watching burn rate, that math matters. ## What I Actually Run on It On a single server through Coolify I run: - The SharMarket Nuxt frontend - Directus as the CMS/backend layer - MySQL database - Redis for queue and cache - Multiple background worker services - Directus file proxy - Cloudflare Tunnel for secure public access - This website All behind automatic SSL, all with isolated environment variables, all manageable from a single dashboard. Setting any of this up manually with raw Docker Compose and Nginx would have taken days and produced something fragile. Coolify turned it into an afternoon. ## What It Costs You Instead Self-hosting is not free. The cost is time and responsibility. When something goes wrong, you fix it. There's no support ticket to open. Disk fills up? That's on you. A service crashes at 2am? Also you. I've learned this the hard way. Disk management, backup retention, monitoring — these are not optional when you self-host. They're the job. Coolify handles a lot, but it doesn't protect you from yourself. If you're a solo developer who wants zero ops overhead, a managed platform is probably the right call. If you're technical, cost-conscious, and want to own your infrastructure, Coolify is the best tool I've found for making that sustainable. ## The Bottom Line Coolify didn't eliminate ops work. It made ops work manageable for a single person running production systems. I can deploy a new app in minutes, spin up a database in seconds, and manage everything from one interface without SSH-ing into the server every time. That's the deal — and for what I'm running, it's a good one. If you're on the fence about self-hosting, start with Coolify on a cheap VPS and see how far it takes you before you need to do anything complicated. It takes you further than you'd expect.
