Your Own Heroku, for $6 a Month
Coolify v4 lets you run your whole web stack on a cheap server you control — apps, databases, and AI tools included — for a fraction of managed-platform prices.
What this is
Coolify is a piece of software you install on a cheap rented server — we're talking $6 a month — and suddenly that server can do what Heroku, Railway, or Render do, but without the monthly bills that creep up the moment you start getting real traffic.
Version 4 just landed, and the big news is how polished it's become. The dashboard was redesigned from scratch. You can now manage multiple servers from one place. And it comes with over 280 tools you can switch on with a single click — things like databases, automation tools, and even local AI models.
One team went from paying around $150 a month on managed hosting down to under $30 on a single Hetzner server. That's not a rounding error — that's a meaningful line item recovered.
Why it matters for your business
If you're running a web product or a client portal, you're probably paying someone to host it. That's fine — until it isn't. Coolify gives you a middle path: you still rent a server (someone else's hardware, no headaches), but the software layer is yours, free, forever.
The new version also connects directly with Claude, Anthropic's AI assistant, which means if you have a developer on your team, they can manage your whole server setup just by having a conversation with it.
Words worth knowing
VPS (Virtual Private Server): A rented computer in a data centre somewhere. You pay by the month. Think of it like leasing a kitchen instead of buying a restaurant building.
Self-hosting: Running software on your own server instead of paying a company to run it for you. More control, usually lower cost, a bit more responsibility.
One-click deploy: Coolify's way of saying "press a button and this tool is running" — no technical setup required beyond the initial install.
MCP (Model Context Protocol): A way for AI assistants like Claude to connect to external tools and actually do things — not just answer questions, but take actions on your behalf.
If you've ever winced at a hosting invoice, it might be worth asking your developer: have you looked at Coolify?
