Comparison

FOSS Cloud Platforms vs Traditional VPS

Traditional VPS wins on control and cost. FOSS cloud platforms (Coolify, CapRover, Dokku) win on developer experience. Choose based on whether you value ops efficiency or infrastructure control.

Scoring Matrix

Scored 1-5 where 5 is best. Traditional VPS = Hetzner/CX21, FOSS Cloud = Coolify on same VPS.

What Is Each Approach?

Traditional VPS (Bare)

A Linux server you manage directly. You install nginx/Apache, configure databases, set up Docker if you want, manage SSL certificates, and deploy applications manually or via scripts. You have full control but full responsibility.

Examples: Hetzner CX21, Netcup RS 2000, Oracle Free Tier VPS

FOSS Cloud Platforms (PaaS)

A self-hosted platform that abstracts away deployment complexity. Git push → running application. Handles SSL, reverse proxy, database provisioning, and log aggregation automatically. You manage the platform; it manages your apps.

Examples: Coolify, CapRover, Dokku, Porter

When to Choose Each

Choose Traditional VPS When...

You want to learn Linux and systems administration
You need maximum resource efficiency (no PaaS overhead)
You run services that don't fit the "web app" model (databases, VPN, mail servers, etc.)
You're building infrastructure-as-code with Ansible/Terraform
You need fine-grained control over every component
You're on a strict budget and every MB of RAM matters
You're comfortable with the command line and want full visibility

Choose FOSS PaaS When...

You want to deploy quickly without deep infrastructure knowledge
You're deploying web applications (Node.js, Python, Ruby, Go, etc.)
You manage multiple projects and want consistent deployment UX
You're tired of configuring nginx virtual hosts manually
You want automatic SSL via Let's Encrypt without certbot scripts
You're a developer who wants ops simplified, not eliminated
You need one-click database provisioning

Resource Usage Comparison

One of the most significant differences is what your workloads actually get. Here are typical RAM usages on a 4 GB VPS:

Setup	Baseline RAM	Available for Apps	Notes
Bare VPS + nginx + Docker	~400 MB	~3.6 GB	Most efficient
Bare VPS + Docker + Coolify	~900 MB	~3.1 GB	~500 MB overhead
Bare VPS + Docker + CapRover	~850 MB	~3.15 GB	Similar to Coolify
Bare VPS + Dokku	~500 MB	~3.5 GB	Lighter than full PaaS

Note: These are approximations. Baseline RAM includes OS, Docker daemon, monitoring agents, and the PaaS platform itself.

Real-World Decision: Three Scenarios

Scenario 1: Personal Blog + VPN + Monitoring

You want to run a personal blog (static site), a WireGuard VPN for yourself, and Uptime Kuma for monitoring. Not a web app, not multiple git-deployable services.

Traditional VPS

Deploy nginx manually, use Docker only for Uptime Kuma. WireGuard goes on bare metal. This uses ~600 MB RAM total. Coolify overhead (500 MB) would waste resources for workloads that aren't even git-deployed.

Scenario 2: Five Node.js Microservices + PostgreSQL

You're a small team running five microservices, a PostgreSQL database, and Redis. You deploy from GitHub, want automatic SSL, and don't want to manage nginx configs.

FOSS PaaS (Coolify)

The developer experience wins. GitHub integration, automatic deployments, built-in database provisioning, and automatic SSL are worth the 500 MB overhead. Your developers spend less time on ops.

Scenario 3: Self-Hosting for Learning

You're a developer who wants to understand how deployment actually works. You want to know what happens when nginx gets a request, how Docker networking works, and how SSL certificates are issued.
