Coolify vs Dokploy vs CapRover vs Dokku: Choosing the Right Self-Hosted PaaS for Your Stack

The self-hosted PaaS landscape has grown from a handful of experimental projects into a genuinely competitive market. Coolify, Dokploy, and CapRover each let you deploy applications on your own servers with a UI that handles builds, routing, SSL, and database management — replacing expensive managed platforms like Heroku, Render, and Railway. And now, with Coolify Cloud offering a managed layer on top of Coolify's open-source engine, there are four distinct options to evaluate.

But choosing the right PaaS is not just about feature lists. It depends on your team size, your deployment patterns, the complexity of your stack, and how much overhead you are willing to manage. This guide is structured as a decision framework: who you are determines which tool is the best fit. For a deeper technical comparison of the three self-hosted options, see our Dokploy vs Coolify head-to-head.

The Options at a Glance

Before diving into use cases, here is a quick orientation on what each option is and what it prioritizes.

Coolify (self-hosted) is the most feature-rich self-hosted PaaS available. It offers a polished UI, built-in monitoring via Sentinel, S3 backup integration, support for 360+ one-click services, Docker Compose support, multi-server management, and an active development cadence. The trade-off is resource consumption: expect roughly 500–700MB of RAM and 5–6% idle CPU usage before deploying any applications.

Coolify Cloud is the managed version of Coolify. You still provide and pay for your own server infrastructure, but the Coolify team handles the Coolify instance itself — updates, maintenance, monitoring of the PaaS layer, and SSH key management. The cost is $5 per month for two connected servers plus $3 for each additional server, on top of your infrastructure costs. You get the same Coolify features without needing to manage the PaaS installation.

Dokploy is the lightest of the four. It consumes roughly 0.8% idle CPU and around 350MB of RAM — meaningfully less overhead than Coolify. Dokploy is Docker-native, built on Docker Swarm with Traefik for reverse proxying. It has native Docker Compose support, multi-server capability, and a clean UI. The community is growing fast, with over 38,000 GitHub stars and frequent releases.

CapRover is the most mature option, available since 2017 (originally as CaptainDuckDuck). It has a large library of one-click app templates, a proven track record for stability, and a straightforward setup process. However, Docker Compose support is limited, the UI feels dated compared to Coolify and Dokploy, and the development pace has slowed. It remains a solid choice for teams that value stability over cutting-edge features.

Dokku is the odd one out: a command-line PaaS with no dashboard (a web UI is sold separately as Dokku Pro), driven by git push dokku main and Heroku-style buildpacks or a Dockerfile, with plugins for PostgreSQL, Redis, Let’s Encrypt and more. MIT-licensed, about 32,000 GitHub stars, version 0.38 at the time of writing, and happy on 1 GB of RAM. It is built for one server, has no Docker Compose deployments and no team accounts, and it is exactly what a developer who misses Heroku’s workflow and dislikes dashboards wants. The self-hosted PaaS hosting page puts all four open-source tools in one table.

Decision Framework by Use Case

The best PaaS for you depends more on your context than on any feature checklist. Here is how the four options map to common team profiles and deployment scenarios.

Solo Developer Shipping Side Projects

You are running a few small apps, maybe a personal site, a SaaS prototype, and a staging environment. Budget matters. You want something that installs fast, gets out of your way, and does not consume half your server's resources before you deploy anything.

Recommendation: Dokploy. The lightweight footprint means you can run Dokploy plus several small applications on a single 2 vCPU / 2GB RAM server without resource pressure. Docker Compose support is native, so your existing docker-compose.yml files work without modification. The UI is straightforward — no steep learning curve.

CapRover is also a reasonable choice here if you prefer one-click app templates over Docker Compose workflows. Coolify works but consumes more baseline resources, which matters on smaller servers.

Small Team (2–5 Developers) with Production Apps

Your team is deploying real workloads — production web apps, APIs, background workers, and databases. You need reliable deployments, monitoring, and enough tooling that you are not SSH-ing into servers to debug issues. Multiple team members need dashboard access.

Recommendation: Coolify (self-hosted) or Coolify Cloud. Coolify's built-in Sentinel monitoring, S3 backup integration, and team management features are designed for exactly this scenario. The UI is the most polished of the four options, which matters when multiple people are using it daily. If your team does not have someone who enjoys managing the PaaS layer itself (updates, troubleshooting Coolify issues), Coolify Cloud at $5/mo per server removes that burden.

Dokploy is a viable alternative if your team is comfortable with a leaner toolset and prefers lower overhead. For a team running 5–10 services on a single server, the difference between 350MB and 700MB of PaaS overhead is meaningful.

Growing Startup Needing Multi-Server Deployments

You have outgrown a single server. Your architecture spans multiple nodes — maybe separate servers for your application, workers, and databases. You need orchestration across machines, and you are thinking about geographic distribution or redundancy.

Recommendation: Coolify or Dokploy. Both support multi-server management from a single dashboard. Coolify has more mature multi-server features, including the ability to manage servers across different providers. Dokploy's multi-server support is built on Docker Swarm, which works well for straightforward multi-node setups. The choice often comes down to whether you value Coolify's broader feature set or Dokploy's lower per-server overhead.

CapRover supports multi-server via Docker Swarm clustering, but the management experience is less refined than either Coolify or Dokploy for this use case.

Enterprise or Compliance-Sensitive Environment

You need audit trails, controlled update schedules, and predictable behavior. Uptime is non-negotiable. You may have regulatory requirements around data sovereignty or access controls.

Recommendation: Coolify (self-hosted) on dedicated infrastructure. Coolify gives you the most granular control over deployment configurations, and self-hosting means your PaaS layer is entirely within your infrastructure boundary. Pair it with Dedicated VPS or Managed Cloud Dedicated servers for guaranteed CPU and memory isolation, plus hardware-level failover. Avoid Coolify Cloud in this scenario — the managed model requires granting SSH access to the Coolify team, which may conflict with compliance requirements.

Dokploy is also suitable for compliance-sensitive deployments, particularly if the lighter footprint allows you to allocate more resources to your actual applications and monitoring stack.

Feature Comparison Matrix

The table below covers the features and characteristics that most commonly drive the decision between these four options.

Resource Footprint: The Numbers That Matter

Every PaaS platform consumes server resources before you deploy a single application. This overhead directly reduces what is available for your actual workloads, and the differences between these four options are significant enough to influence your server sizing decisions.

Coolify (Self-Hosted and Cloud)

Coolify runs the most services at idle — the main application, a PostgreSQL database, Redis, and optionally the Sentinel monitoring agent. Expect approximately 5–6% idle CPU usage and 500–700MB of RAM consumption before deploying any applications. On a 2 vCPU / 4GB server, that is roughly 15–18% of your available memory consumed by the platform itself. Coolify Cloud has the same footprint because the Coolify instance still runs on your server — the managed service handles updates and maintenance, not hosting.

Dokploy

Dokploy is meaningfully lighter. At idle, it consumes approximately 0.8% CPU and roughly 350MB of RAM. That is less than half the RAM overhead of Coolify. On the same 2 vCPU / 4GB server, Dokploy leaves you with roughly 3.6GB for your applications versus 3.3–3.5GB with Coolify. The difference scales: on a 2GB server, that extra 200–350MB of headroom can be the difference between running comfortably and running out of memory.

CapRover

CapRover falls between the two, with approximately 2–3% idle CPU and roughly 400MB of RAM. It runs Nginx as its reverse proxy (versus Traefik for Coolify and Dokploy), and the overall architecture is simpler with fewer background services. The footprint is moderate — not as lean as Dokploy, but noticeably lighter than Coolify.

Dokku

Dokku is the lightest of all because it has nothing to run at idle: no dashboard, no database, no agent, just Docker and the Nginx (or Traefik or Caddy) proxy plugin. Its documentation asks for 1 GB of RAM (or swap) and the overhead above the proxy is a few tens of megabytes. On a 1 vCPU / 2 GB server almost the whole machine is left for your applications, which is why Dokku remains the choice for a single developer squeezing a side project onto the smallest server.

What This Means for Server Sizing

If you are running on a 1 vCPU / 2GB server (the common entry point for self-hosted PaaS), the platform overhead matters a lot. Dokploy leaves you with approximately 1.6GB for applications; Coolify leaves you with 1.3–1.5GB. That 200–300MB gap is roughly one additional small application or database container. On larger servers (4+ vCPU / 8GB+ RAM), the proportional impact shrinks, and feature differences become more important than footprint differences.

Coolify Cloud vs. Self-Hosted Coolify: The $5/Month Question

Coolify Cloud is not a separate product — it is Coolify, managed by the Coolify team. You still need your own server. You still pay for your infrastructure. The $5 per month (two servers included, $3 per additional server) buys you managed updates, the Coolify team handling SSH key management, and support for PaaS-layer issues.

When Coolify Cloud Is Worth It

• You do not want to manage the PaaS itself. If your focus is on deploying applications and you view the PaaS as infrastructure that should just work, paying $5 to $8/mo to avoid managing Coolify updates and troubleshooting PaaS issues is a reasonable trade.
• You are a small team without dedicated DevOps. The time cost of keeping Coolify updated, debugging update failures, and managing SSH keys across servers adds up. At $5/mo for two servers, the ROI is obvious if it saves even an hour per month.
• You want faster access to new features. Coolify Cloud instances are updated by the Coolify team, typically before self-hosted users apply updates themselves.

When Self-Hosted Makes More Sense

• You have compliance or security requirements. Coolify Cloud requires granting the Coolify team SSH access to your servers. If your security policy prohibits third-party SSH access, self-hosted is the only option.
• You manage many servers. At $5 per server per month, a 10-server deployment adds $50/mo — $600/year. At that scale, the economics shift toward having someone on your team manage Coolify directly.
• You want full control over update timing. Self-hosted means you decide when to update, which matters for production environments where you need to test updates before applying them.

Where Dokku Fits

Searches for "Coolify vs CapRover vs Dokku" are common because the three are the long-standing open-source PaaS options and Dokku is the one without a UI. The table compares what differs; figures are from the projects’ repositories and docs on 31 October 2026.

Choose Dokku when you want Heroku’s git push on one server and would rather script than click. Choose CapRover over Dokku when you want a dashboard and one-click apps without Coolify’s footprint. Choose Coolify or Dokploy over both when your applications are Compose stacks, when more than one person deploys, or when you expect a second server. Dokku runs on the same $9.58 Starter preset as the others, with the most headroom of the four.

The Decision Tree

If the framework above still leaves you undecided, this quick-reference decision tree maps specific needs to specific tools.

Infrastructure Recommendations by PaaS

The PaaS you choose should inform your server selection. Different resource profiles mean different infrastructure fits best.

Dokploy: Start with Cloud VPS

Dokploy's low overhead means you can start on a smaller server than the other options. A Cloud VPS with 2 vCPU and 2–4GB RAM is sufficient for Dokploy plus several small-to-medium applications. The shared compute model keeps costs low, and you can independently scale CPU, RAM, and storage as your workload grows. For production workloads that need consistent performance, step up to a Dedicated VPS — you get guaranteed CPU cores without the noisy-neighbor risk.

Coolify: Benefit from Dedicated Resources

Coolify's higher baseline consumption means it benefits more from dedicated CPU cores. The 5–6% idle CPU is more predictable on a Dedicated VPS where you are not sharing physical cores with other tenants. Start with 2 dedicated vCPU and 4GB RAM as a minimum for Coolify plus a few applications. For multi-server setups, the management node (running Coolify itself) should be on dedicated resources even if worker nodes use shared compute. If you are new to Coolify, our step-by-step installation guide covers everything from server provisioning to first deployment.

CapRover: Cloud VPS Works Well

CapRover's moderate resource footprint fits well on a Cloud VPS. Its Nginx-based reverse proxy is efficient, and the overall architecture is straightforward. A 2 vCPU / 2–4GB server handles CapRover plus several applications comfortably. For scaling, CapRover uses Docker Swarm clustering — add worker nodes as needed.

Coolify Cloud: You Still Need Your Own Server

An important clarification: Coolify Cloud does not host your applications. You still provision and pay for your own servers. Coolify Cloud manages the Coolify installation on your server for $5/mo covering two servers, plus $3/mo for each additional server. The infrastructure recommendations are the same as self-hosted Coolify — Dedicated VPS for production, Cloud VPS for development and staging. The difference is that you are not responsible for keeping Coolify itself updated and running.

Conclusion: Match the Tool to Your Context

There is no universally best self-hosted PaaS. The right choice depends on your team size, your technical comfort level, your resource constraints, and how you prioritize features versus overhead.

Dokploy wins on efficiency. If you are a solo developer, budget-conscious, or running on smaller servers, its minimal footprint and clean Docker-native approach mean more of your server goes to your applications instead of your platform.

Coolify wins on features. If you are a team that needs monitoring, backup integration, extensive one-click services, and the most polished management UI, the extra resource overhead is the cost of having the most capable tool.

Coolify Cloud wins on convenience. If you want Coolify's features without managing Coolify itself, $5/mo for two servers and $3 for each one more is a straightforward trade of money for time.

CapRover wins on maturity. If you value a long track record, a battle-tested one-click app library, and do not need Docker Compose support or the latest UI polish, CapRover is the known quantity.

Whichever PaaS you choose, the infrastructure underneath determines your actual performance, reliability, and cost. Start with the right server tier for your workload, scale the specific resources that become bottlenecks, and upgrade to dedicated resources when your applications need guaranteed performance. The PaaS is the deployment abstraction. The infrastructure is what your users actually experience.

Frequently Asked Questions

Coolify vs Dokku: which should I pick?

Dokku if you are one developer who wants Heroku’s git push workflow on a single small server and prefers the command line; it has no dashboard, no Compose deployments and no team accounts, and it idles at almost nothing. Coolify if more than one person deploys, your applications are Docker Compose stacks, you want one-click services, monitoring and backups in a UI, or you expect to add servers. Both are free and open source and both run on the same $9.58 Starter preset.

Is CapRover still worth choosing in 2026?

For single-container applications and one-click apps on a tool that has not changed much in years, yes: it is stable, Nginx-based and well documented by nine years of forum answers. Its limits are Docker Compose support, a single admin password and a slower release pace than Coolify or Dokploy, so teams and Compose-heavy stacks usually pick one of those two instead. Our Dokploy vs CapRover post covers the migration if you outgrow it.

Which self-hosted PaaS uses the least RAM?

Dokku, because it runs nothing at idle beyond Docker and the proxy plugin and its docs accept 1 GB of RAM. Among the dashboard tools Dokploy is lightest at roughly 350 to 450 MB idle, CapRover sits around 400 MB, and Coolify uses 500 to 700 MB because it runs its own PostgreSQL, Redis and optional Sentinel agent. On a 4 GB server the difference is a few hundred megabytes; on a 2 GB server it decides how many applications fit.
