Dokploy vs Coolify: Which Self-Hosted PaaS Should You Use on Your VPS in 2025?

Coolify has been the dominant self-hosted PaaS for VPS deployments since 2023. Dokploy emerged as a compelling alternative in 2024, with a simpler setup, stable Docker Swarm support for multi-node deployments, and significantly lower RAM footprint. Both are open-source, both run on your VPS, and both deliver a Vercel/Heroku-like deployment experience on hardware you control.

What Both Tools Do

Dokploy and Coolify both serve the same core purpose: deploy applications on a VPS with git-push automation, automatic SSL, database provisioning, and a web UI. Both support:

• Git integration (GitHub, GitLab, Gitea)
• Automatic SSL via Let’s Encrypt
• One-click database provisioning (PostgreSQL, MariaDB, Redis, MongoDB)
• Nixpacks auto-detection, Dockerfile, Docker Compose, pre-built images
• Preview deployments and environment variable management

Side-by-Side Comparison

Installation Commands

# Coolify
curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash
# Dashboard: http://YOUR_VPS_IP:8000

# Dokploy
curl -sSL https://dokploy.com/install.sh | sh
# Dashboard: http://YOUR_VPS_IP:3000

Key Differences in Practice

Reverse Proxy

Coolify (Traefik): Dynamic routing — no restart needed when adding new services. Let’s Encrypt SSL provisioned automatically via Docker container labels. Some developers find Traefik’s model less intuitive than Nginx.

Dokploy (Nginx): Familiar to most Linux admins, transparent configuration you can inspect and understand. Traefik is available as an optional backend.

Multi-Server Architecture

Coolify: Manages multiple independent servers from one dashboard. Each server runs separate Docker containers. Best for independent services on separate VPS instances.

Dokploy: Docker Swarm support deploys the same service across multiple nodes with automatic load balancing and failover. Better for horizontal scaling of a single application.

Resource Usage on a 2 GB VPS

• Coolify idle: ~750 MB–1.2 GB overhead → ~800 MB–1.2 GB available for your apps
• Dokploy idle: ~200–400 MB overhead → ~1.6 GB available for your apps

Choose Coolify if:

• You want the most mature, battle-tested self-hosted PaaS with the largest community
• You need the widest one-click service catalog (Ghost, n8n, Gitea, Plausible, Metabase, etc.)
• You are managing multiple independent VPS instances from a central dashboard
• You want Coolify Cloud as a managed fallback option
• Your VPS has 4+ GB RAM where the overhead difference doesn’t matter

Choose Dokploy if:

• Your VPS has 2 GB RAM and you need maximum memory for applications
• You need Docker Swarm for horizontal scaling across multiple nodes
• You prefer Nginx’s familiarity over Traefik’s label-based routing model
• You want a simpler initial setup with fewer configuration decisions
• You are interested in a faster-moving, newer project

Getting Started

Both require KVM virtualization for Docker. KVM VPS plans at VPS.DO support both tools fully. The 2 vCPU / 2 GB RAM plan is the minimum for Coolify; 2 vCPU / 4 GB is recommended when deploying multiple applications. The same 2 GB plan is comfortable for Dokploy with 5+ applications running simultaneously.

Conclusion

Coolify is the safer, more mature choice with a larger ecosystem and community. Dokploy is the lighter-weight, faster-evolving alternative with better Docker Swarm integration and significantly lower RAM overhead. Both deliver git-push deployments with automatic SSL on your own VPS. For most users, Coolify’s maturity outweighs Dokploy’s resource efficiency — unless you specifically need Docker Swarm or have a resource-constrained 2 GB VPS where every MB of RAM matters.
