Hetzner vs Coolify for Solo Developers

Quick Comparison

Hetzner Overview

Hetzner is a European cloud provider known for offering absurd value. Their entry-level x86 VPS, the CX23, gives you 2 vCPUs, 4GB RAM, 40GB SSD, and 20TB of monthly traffic for EUR 3.99/month (it nudged up from EUR 2.99 in the April 2026 price adjustment, and still undercuts everyone). The ARM CAX11 has the same specs at EUR 4.49/month. Try getting that anywhere else. You won't. Dedicated servers add real bare metal that would cost you several times as much at AWS or GCP for comparable hardware.

I run production workloads on Hetzner and the reliability has been solid. Uptime consistently above 99.9%, fast network, and German engineering applied to data centers. The catch is that Hetzner gives you a server and nothing else. No managed databases, no deployment pipelines, no app platform. You SSH in, you install things, you configure everything manually. If your Nginx config breaks at 2 AM, that's your problem.

For solo developers comfortable with Linux administration, Hetzner is the best deal in cloud computing. For those who aren't, it can be a time sink that pulls you away from building your product.

Coolify Overview

Coolify is an open-source, self-hosted PaaS that turns any VPS into your own Heroku. You install it on a server (takes about 5 minutes), point it at your Git repository, and it handles builds, deployments, SSL certificates, and reverse proxying automatically. Docker-based, with support for 280+ one-click services like PostgreSQL, Redis, MinIO, and Plausible Analytics. The project is written in PHP (Laravel), sits at over 56,000 GitHub stars, and ships fast, the v4.1.1 release landed on 2026-05-27.

The dashboard is genuinely well-designed. You see all your projects, their deployment status, resource usage, and logs in one place. Push to Git, Coolify builds and deploys. Need a database? Click a button. Need SSL? It handles Let's Encrypt automatically. Need environment variables? There's a panel for that.

Coolify also offers a cloud-hosted version if you don't want to manage the Coolify installation itself. The base Cloud plan is $5/month and lets you connect up to 2 servers, with each additional server adding $3/month (annual billing saves 20%). You still bring your own servers from any provider, so Cloud is paying for the managed control panel only. But most solo developers install it on a cheap VPS and get the full experience for free, the self-hosted edition is free forever with no feature limits.

Key Differences

They solve different problems. This is the most important thing to understand. Hetzner gives you a server. Coolify gives you a deployment platform. They're not alternatives, they're complementary. Most Coolify users run it on a Hetzner VPS because the combination gives you a Heroku-like experience at VPS prices.

Management overhead. With Hetzner alone, you manage everything: Nginx, SSL, Docker, deployments, databases, backups. With Coolify on top, it manages deployments, SSL, reverse proxying, and service provisioning. You still manage the underlying server (updates, security), but the application layer is handled.

Cost structure. Hetzner charges for compute resources. Coolify is free when self-hosted. Running self-hosted Coolify on a Hetzner CX23 (EUR 3.99/mo) gives you a full PaaS for the price of the server alone, roughly $4 to $5/month all in. Compare that to a managed platform like Heroku or Railway once you add a dyno, a database, and bandwidth, and the savings are enormous.

Scaling approach. Hetzner scales by upgrading server size or adding more servers. Coolify supports multi-server deployments, so you can add Hetzner servers to your Coolify cluster as you grow. It's not Kubernetes-level orchestration, but for a solo developer it handles growth well.

Ecosystem and services. Hetzner has load balancers, floating IPs, volumes, and object storage. Coolify has one-click deployment of 280+ services (databases, monitoring, analytics). Together they cover most needs without touching a managed service provider.

By the Numbers (2026)

Here is the verified state of both tools as of 28 May 2026. These are the figures that actually move the decision, with sources listed at the end.

Hetzner Cloud (pricing effective 1 April 2026)

• CX23, the entry-level x86 plan: 2 vCPU, 4 GB RAM, 40 GB SSD, 20 TB traffic, EUR 3.99/month (up from EUR 2.99 before the April adjustment).
• CAX11, the entry-level ARM plan (Ampere): 2 vCPU, 4 GB RAM, 40 GB SSD, 20 TB traffic, EUR 4.49/month in the Germany and Finland regions.
• You can deduct EUR 0.50/month if you skip the IPv4 address.
• Billing is hourly with a monthly cap, so spinning a server up for a few days costs cents.

Coolify

• Latest release: v4.1.1, published 2026-05-27.
• Built in PHP on Laravel, Docker-based.
• Over 56,000 GitHub stars and roughly 4,600 forks on the coollabsio/coolify repository.
• 280+ one-click services advertised, and 3,641+ paying customers on Coolify Cloud per the project's homepage.
• Self-hosted edition: free forever, full features, no limits.
• Coolify Cloud: $5/month base for up to 2 connected servers, plus $3/month for each additional server, with 20 percent off on annual billing. This pays for the control panel only; you still rent the actual servers elsewhere.

Coolify is open source and PHP-based rather than a published npm package, so there is no npm weekly-download figure to cite. The relevant adoption signal is the GitHub star count and the install-script-based deployment, not a registry download number.

Real Cost at Solo-Dev Scale

Take a realistic solo-developer workload: a SaaS app, its PostgreSQL database, a Redis cache, and a small monitoring service, all on a single server with room to grow. Here is what each path actually costs per month, using the rates above.

Path A, self-hosted Coolify on one Hetzner CX23. Server EUR 3.99 plus Coolify self-hosted at EUR 0. Total: EUR 3.99/month for the whole stack, app, database, cache, and monitoring included, because Coolify deploys all four as containers on the one box. In USD that lands near $4 to $5/month depending on the exchange rate.

Path B, Coolify Cloud managing one Hetzner CX23. Server EUR 3.99 plus Coolify Cloud $5/month for the managed control panel (one server fits inside the 2-server base tier). Total: roughly $9 to $10/month. You trade about $5 a month to never patch or back up the Coolify installation yourself.

Path C, growing to three servers on Coolify Cloud. Three CX23 servers at EUR 3.99 each is about EUR 12, plus Coolify Cloud at $5 base + $3 + $3 for the two extra servers, which is $11/month for the panel. Total in the low-to-mid $20s per month for a three-node setup with a managed control plane. The same three nodes under self-hosted Coolify stay at just the EUR 12 of server cost.

Assumptions: EUR-to-USD treated as roughly one-to-one for a rough monthly estimate, single-region Germany or Finland pricing, IPv4 included, and one CX23 comfortably running the four containers in the example. The takeaway holds across every path: the deployment layer is either free or a few dollars, and the server is the only real line item. That is the structural reason this pairing beats managed platforms for a solo developer.

When to Choose Hetzner (Alone)

• You enjoy full control and prefer manual server configuration
• You're running custom infrastructure that doesn't fit a PaaS model (like K3s or Nomad)
• You need dedicated servers for heavy workloads
• You already have your own deployment pipeline (GitHub Actions, Kamal, etc.)
• You want to learn Linux administration hands-on

When to Choose Coolify

• You want Heroku-like deployments without Heroku pricing
• You want to deploy multiple services (app, database, Redis, monitoring) from one dashboard
• You don't want to manually configure Nginx, SSL, and Docker Compose for every project
• You want Git-push deployments with automatic SSL
• You're running several side projects and need a central management interface

The Verdict

This comparison is a bit of a trick question because the best answer is usually both. Install Coolify on a Hetzner VPS and you get the cheapest, most capable self-hosted platform available to solo developers. You get Hetzner's unbeatable price-to-performance ratio combined with Coolify's deployment automation.

If I had to pick just one, Coolify wins for most solo developers because it solves the deployment problem that actually slows you down. A bare Hetzner server requires hours of configuration before you deploy your first app. Coolify gets you deploying in minutes.

But seriously, the play is Hetzner + Coolify together. EUR 3.99/month for a full PaaS. That's less than a coffee, and it'll run your SaaS, your blog, your databases, and your monitoring stack. Nothing else in the hosting world comes close to that value.
