Coolify vs CapRover vs Dokku: The Self-Hosting Platform Showdown

You’ve got a VPS. You want to deploy apps on it. But the idea of manually wrangling Docker Compose files, Traefik configs, and SSL certificates makes you want to go back to Heroku.

I get it. I’ve been there.

Good news: there are platforms that handle all of this for you — on your own server. The big three in 2026 are Coolify, CapRover, and Dokku.

I’ve deployed dozens of apps across all three. Each one has its fans, and honestly, they’re all pretty good. But which one should you pick? Let me break it down.

The Quick Verdict

	Coolify	CapRover	Dokku
Best for	Most people	Tinkerers	CLI lovers
UI	⭐⭐⭐⭐⭐	⭐⭐⭐	❌ (CLI only)
Ease of setup	⭐⭐⭐⭐⭐	⭐⭐⭐⭐	⭐⭐⭐
One-click apps	100+	50+	Via plugins
Resource usage	~300 MB	~200 MB	~100 MB
Multi-server	✅	✅	❌
Git push deploy	✅	✅	✅
Docker Compose	✅	❌	❌
Active development	Very active	Moderate	Stable
License	Apache 2.0	Apache 2.0	MIT

TL;DR: Coolify if you want the best overall experience. Dokku if you love the CLI and want minimal overhead. CapRover if you’re stuck between the two.

Coolify: The Modern PaaS

Coolify has become the most popular self-hosting platform, and I understand why. It’s basically a self-hosted Vercel/Netlify/Heroku that actually works, running on your own servers.

What Makes Coolify Special

First thing: the UI is gorgeous. This isn’t some clunky admin panel from 2010. It looks and feels like a modern SaaS product. Dark mode, responsive design, real-time logs that actually update without refreshing. The deployment flow is intuitive. You’re not fighting the interface.

Docker Compose support is a game-changer. Unlike CapRover and Dokku, Coolify can deploy entire Docker Compose stacks. Got a docker-compose.yml with a web app, database, Redis, and some sidecar services? Paste it in. Coolify handles the networking, SSL, routing, the whole deal. This alone was a deal-breaker for me switching from CapRover.

One-click services let you spin up databases, caches, and popular apps without touching config files. Need PostgreSQL? One click. Redis? One click. Plausible Analytics? One click. For someone coming from Heroku, this is comforting.

Setting Up Coolify

Installation is genuinely painless:

curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash

Two minutes later, you’ve got a full PaaS running on your server, accessible at http://your-ip:8000. No Docker Compose wrestling, no building from source. Just works.

Coolify Strengths

Multi-server management — I manage three separate VPS instances from one dashboard, and it doesn’t feel janky
Docker Compose support — Deploy complex multi-container stacks without hand-rolling everything
Automatic SSL via Let’s Encrypt (applies to everything)
Built-in monitoring — Resource graphs per app and per server
Scheduled backups for databases, stored on S3 if you want
Webhook deployments — Push to GitHub, auto-deploy. Works as expected
Very active development — New features every week, bugs get fixed fast

Coolify Weaknesses

Resource hungry — The platform itself uses ~300-500 MB RAM. On a 2 GB VPS, this matters
Young project — You’ll occasionally hit a bug. The team fixes them quickly, but you’re on the bleeding edge
Opinionated — Less flexibility than raw Docker if you need weird edge cases

Who Should Use Coolify

Coolify is the right choice for most people. If you want a beautiful, modern platform that just works and you don’t mind the resource overhead, go with Coolify. Pick it if you:

Want to deploy from Git repositories
Need Docker Compose support
Manage multiple servers
Want a UI that doesn’t make you want to cry
Came from Vercel/Heroku/Railway and miss the simplicity

CapRover: The Middle Ground

CapRover has been around since 2017 (originally called CaptainDuckDuck) and sits nicely between Coolify’s feature-richness and Dokku’s minimalism.

What Makes CapRover Special

It does one thing well: takes your code or Docker image and deploys it with SSL. The web interface is functional. Not fancy. But it works. The one-click app library covers most of what you actually need.

Custom Dockerfile support is solid. Point it at a repo with a Dockerfile, and it builds and deploys. No surprises.

Setting Up CapRover

# Install CapRover
docker run -p 80:80 -p 443:443 -p 3000:3000 \
  -e ACCEPTED_TERMS=true \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v captain-data:/captain \
  caprover/caprover

Then configure it via the CLI:

npm install -g caprover
caprover serversetup

CapRover Strengths

Lower resource footprint (~200 MB) than Coolify
Stable and battle-tested — It’s been around long enough to have real users
One-click apps with a decent library
Cluster mode — Scale across multiple servers using Docker Swarm
Custom Nginx configs if you need to tweak things
CLI and web UI both available

CapRover Weaknesses

No Docker Compose support — Apps are single-container only. This is a real limitation for anything non-trivial
Dated UI — Functional but not pretty. You get used to it
Slower development pace — Updates happen, but not at Coolify’s speed
Docker Swarm reliance (the industry mostly moved on)
Database management is minimal compared to Coolify

Who Should Use CapRover

CapRover is good for you if:

You want something lighter than Coolify
Your apps are genuinely single-container
Swarm clustering matters for your use case
You prefer a more proven, battle-hardened platform
You don’t mind the UI trade-off

Dokku: The Heroku Clone

Dokku calls itself “the smallest PaaS implementation you’ve ever seen.” Accurate. It’s a collection of shell scripts that gives you Heroku-like git push deployments on your own server. No bloat.

What Makes Dokku Special

Minimal overhead. Dokku barely touches your system (~100 MB). Everything else is available for your actual apps. If you’re resource-constrained, this matters.

Heroku compatibility. Already used Heroku? Dokku uses the same buildpacks, same git push workflow, same Procfile. The mental model transfers directly.

Plugin ecosystem. Dokku’s features come from plugins — databases, caching, cron, Let’s Encrypt, all opt-in. You install only what you need.

Setting Up Dokku

# Install Dokku
wget -NP . https://dokku.com/bootstrap.sh
sudo DOKKU_TAG=v0.35.0 bash bootstrap.sh

Then configure via the web installer or straight CLI:

# Add your SSH key
cat ~/.ssh/id_rsa.pub | dokku ssh-keys:add admin

# Create an app
dokku apps:create myapp

# Add a domain
dokku domains:set myapp myapp.yourdomain.com

# Deploy
git remote add dokku dokku@your-server:myapp
git push dokku main

Done.

Dokku Strengths

Minimal resource usage — ~100 MB overhead means more room for your apps
Heroku-compatible — Buildpacks and workflows feel familiar
Rock solid — One of the oldest self-hosting projects around
Plugin architecture — Install what you need, nothing you don’t
Simple mental model — Apps, domains, config. That’s the scope
Excellent documentation

Dokku Weaknesses

CLI only — No web interface. If you hate the terminal, stop reading
Single server only — No built-in multi-server support
No Docker Compose — Single-container apps, like CapRover
Learning curve — You need to be comfortable with the command line
Buildpack limitations — Some apps don’t fit the buildpack model

Who Should Use Dokku

Pick Dokku if:

You’re comfortable (or prefer) the terminal
Resource efficiency is your priority
Your apps are simple (not complex multi-container stacks)
You’ve used Heroku and miss that workflow
You want the most battle-tested, no-nonsense option

Head-to-Head Comparisons

Deployment Workflow

Coolify: Connect your GitHub/GitLab repo → configure build settings in the UI → deploy. Or paste a docker-compose.yml. Webhooks auto-deploy on push.

CapRover: Connect your repo or upload a tarball → CapRover builds your Dockerfile → deploy. CLI or web UI both work.

Dokku: git push dokku main. Buildpacks auto-detect your app type. Done. If you need a Dockerfile, use that instead.

Winner: Coolify for flexibility, Dokku for simplicity.

Database Management

Coolify: One-click PostgreSQL, MySQL, MongoDB, Redis, etc. Built-in backup scheduling to S3. Connection strings auto-configured. You can actually forget about backups.

CapRover: One-click app library for databases. Management is more hands-on. No built-in backup scheduling (you remember to do it yourself, right?).

Dokku: Plugin-based. dokku postgres:create mydb. dokku postgres:link mydb myapp. Backup plugins exist but aren’t built in.

Winner: Coolify, and it’s not close.

SSL/TLS

All three support automatic Let’s Encrypt certificates. Coolify and CapRover handle it automatically. Dokku requires the dokku-letsencrypt plugin (two commands, no big deal).

Winner: Tie.

Monitoring

Coolify: Built-in resource monitoring. Graphs per app, per server, in real time.

CapRover: Basic monitoring in the dashboard.

Dokku: No built-in monitoring. Use external tools like Uptime Kuma.

Winner: Coolify.

Community and Support

Coolify: Very active Discord. GitHub issues get responses fast. Sponsored development (sustainable).

CapRover: Moderate community. GitHub-based support.

Dokku: Large, established community. Documentation is excellent. Slack channel is active.

Winner: Tie, but for different reasons.

Resource Usage Comparison

I tested all three on a fresh Hetzner CAX11 (2 vCPU ARM, 4 GB RAM) with the same app deployed (Node.js API + PostgreSQL):

Metric	Coolify	CapRover	Dokku
Platform RAM (idle)	380 MB	210 MB	95 MB
Platform RAM (1 app)	520 MB	310 MB	140 MB
Platform disk usage	1.2 GB	800 MB	300 MB
Boot time	~45s	~30s	~15s
First deploy time	~3 min	~4 min	~2 min

On a tight-resource VPS (1-2 GB RAM), Dokku gives you the most headroom. But real talk: a 4 GB Hetzner VPS costs €6/month. The resource difference stops mattering at that price point.

Our Recommendation

Choose Coolify if…

You’re new to self-hosting
You want the best overall experience (and it shows)
You need Docker Compose support
You manage multiple servers
You want built-in database management and backups

Choose CapRover if…

You want a lighter alternative to Coolify
Docker Swarm clustering actually matters for your setup
You prefer a more proven, stable platform
Your apps are simple (single container)

Choose Dokku if…

You love the command line
Resource efficiency is critical
You have a Heroku background
You deploy simple apps
You want maximum control with minimum overhead

The 2026 Pick: Coolify

For most people reading this, Coolify is the best choice in 2026. It’s the most feature-rich, actively developed, and beginner-friendly. Yes, it uses more resources. But a 4 GB Hetzner VPS costs €6/month. You get plenty of room.

The Docker Compose support is the real differentiator. Most real-world apps need multiple containers. With Coolify, you paste YAML. With the others, you’re rebuilding things or deploying separate apps.

That said, all three are excellent projects. Use what fits your brain. The best platform is the one you’ll actually maintain.
