Coolify vs Dokku: Self-Hosted PaaS Platforms Compared

The two most popular self-hosted PaaS platforms. Coolify offers a modern web UI with one-click deployments. Dokku is the minimalist Heroku clone that runs entirely from the CLI. Both turn a VPS into a deployment platform. Here's how they compare.

Quick Verdict

Choose Coolify for the best self-hosted PaaS experience — web dashboard, one-click services, built-in monitoring, and multi-server support. Choose Dokku for Heroku-like CLI simplicity — git push dokku main and you're deployed.

When to Choose Coolify

• You want a web dashboard for deployments
• One-click database/service provisioning matters
• Multi-server management (deploy to multiple VPS)
• Built-in monitoring and log viewing
• Scheduled backups without extra tools
• Team collaboration (multiple users)
• Docker Compose deployments (native support)
• Non-CLI users on the team

When to Choose Dokku

• You love the Heroku CLI workflow
• git push deployments are your thing
• Minimal resource footprint (runs on 512 MB VPS)
• Single-server simplicity
• Heroku buildpack compatibility matters
• Maximum stability (10+ years of production use)
• You prefer CLI over web interfaces
• Plugin ecosystem for extending features

Deployment Comparison

Coolify:

1. Install Coolify on your VPS (one command)
2. Open the web UI
3. Click "New Resource" → connect GitHub repo
4. Configure environment variables in the UI
5. Click "Deploy"
6. View logs, monitoring, and status in the dashboard

Dokku:

# On server
dokku apps:create myapp
dokku postgres:create myapp-db
dokku postgres:link myapp-db myapp
dokku config:set myapp NODE_ENV=production

# On your machine
git remote add dokku dokku@server:myapp
git push dokku main

Both get you deployed quickly. Coolify is more visual. Dokku is more scriptable.

The Heroku Compatibility Advantage

Dokku was built as a mini-Heroku. If you're migrating from Heroku:

• Same buildpacks work
• Same Procfile format
• Same git push workflow
• Same environment variable management
• Same scaling commands (similar syntax)

Coolify uses Nixpacks by default (auto-detects language and builds). It also supports Dockerfiles and Docker Compose, making it more flexible but less "Heroku-like."

The Bottom Line

Coolify is the modern choice — web UI, multi-server, monitoring, one-click services. It's what you'd build if you designed a self-hosted PaaS in 2024. Best for teams and people who want a visual deployment platform.

Dokku is the classic choice — CLI-first, Heroku-compatible, minimal footprint. It's been battle-tested for a decade. Best for developers who want the simplest possible git push deployment.

If you're migrating from Heroku, Dokku is the easiest transition. If you're building a new deployment workflow from scratch, Coolify offers more out of the box.
