The short version
- Each has a real cost: Coolify commit history since June 2026 shows one maintainer at 73 commits and a second at 15 with nobody else above one, and the same two people also ship four other coolLabs products, so the project depends on a very small number of individuals.; Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
- They diverge on capability: Coolify covers Git push deployments, Docker covers Container runtime.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Coolify
- Commit history since June 2026 shows one maintainer at 73 commits and a second at 15 with nobody else above one, and the same two people also ship four other coolLabs products, so the project depends on a very small number of individuals.
- Multi-server support is documented as experimental, load balancer configuration is manual, every server must share the same CPU architecture, and moving images between hosts requires you to run your own Docker registry.
- In self-hosted mode the Coolify machine holds every SSH key and secret with no documented high availability, so the dashboard host is a single point of failure that the paid Cloud tier fixes and self-hosting does not.
- Scheduled S3 backups cover PostgreSQL, MySQL, MariaDB and MongoDB only, so application persistent volumes are your responsibility and a restore is untested unless you test it yourself.
- Release cadence is fast enough that six patch versions shipped inside ten days in August 2026 against several hundred open issues, and because instances can update themselves a regression can reach a production host before you have read the changelog.
Docker
- Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
- Daemon socket exposure grants full root access to the host if compromised
- Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
- Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
- Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Questions people ask
- Is Coolify or Docker better?
- Neither clearly leads. Coolify starts at Free and Docker at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Coolify or Docker?
- Coolify starts at Free and Docker at Free.
- Does Coolify or Docker run on more platforms?
- Coolify runs on Web, Linux, Docker, Self-hosted. Docker runs on Linux, macOS, Windows.
- Can I use Coolify for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Coolify best used for?
- Coolify is most often used for replacing a managed platform bill with a single hetzner or digitalocean instance running a dozen small applications, an agency hosting many low-traffic client sites on shared servers with certificates handled automatically, self-hosting analytics, databases and internal tools from the one-click catalogue without writing compose files, deploying inside a country or jurisdiction where no managed platform operates a region. Of those, replacing a managed platform bill with a single hetzner or digitalocean instance running a dozen small applications and an agency hosting many low-traffic client sites on shared servers with certificates handled automatically are not what Docker is typically brought in for.
- What can Coolify do that Docker cannot?
- Coolify covers Git push deployments, One-click services, Automatic certificates, Managed databases. Docker covers Container runtime, Docker Desktop, Docker Hub, Docker Compose.
Answered from the vendors’ own pages
Coolify: Is anything held back for the paid tier?
No. Coolify Cloud hosts, updates and backs up the dashboard and gives it high availability. Every feature that touches your applications is in the Apache-2.0 build you can run yourself.
Docker: What is Docker pricing?
Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.
SourceCoolify: What does Coolify Cloud cost?
Five US dollars a month connects two servers, and each additional server is three dollars a month, with 20 per cent off for annual billing. You still supply and pay for the servers themselves.
Docker: Can I use Docker in production?
Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.
SourceCoolify: Does it back up my application data?
It backs up PostgreSQL, MySQL, MariaDB and MongoDB to S3 on a schedule. Application persistent volumes are not covered, so anything stored outside a managed database needs your own backup plan.
Docker: What are the main security concerns with Docker?
Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.
SourceCoolify: Can I run it across several servers?
Yes, but the documentation calls multi-server experimental. Load balancing is not configured for you, all nodes must share a CPU architecture, and you need to run your own Docker registry.
Docker: Does Docker integrate with CI/CD systems?
Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.
