Coolify

What Coolify actually is

Coolify is an open source, self-hostable platform-as-a-service that gives you the deployment experience of Heroku or Vercel on servers you already pay for. Point it at any Linux machine with SSH access — a small VPS, a dedicated box, a spare laptop, even a Raspberry Pi — and it installs Docker, wires up a reverse proxy with automatic Let's Encrypt certificates, and turns git pushes and one-click templates into running containers. We would describe it as a private control plane for self-hosting: you keep the infrastructure, Coolify removes most of the operational tedium around it.

The project was started in 2021 by András Bácsai as a solo open source effort and has since become one of the most-starred self-hosting projects on GitHub — on the order of 50,000 stars, depending on when you count. The current v4 line is a full rewrite in PHP (Laravel) with a Svelte frontend; earlier generations ran on Node.js. It ships under the Apache 2.0 license, which is the most permissive tier in serious open source: you can fork it, modify it, and embed it in a commercial product. There is no enterprise edition and no feature paywall, a point the project makes explicitly on its own pages and one we consider the right call for this category.

Functionally, Coolify covers what most teams actually run: applications built from Docker images or from git repositories (GitHub, GitLab, Bitbucket integrations for push-to-deploy), static sites, databases (PostgreSQL, MySQL, Redis, MariaDB and others provisioned with volumes and scheduled backups), and more than 280 one-click service templates — the usual self-hosted catalog of queues, dashboards, analytics and storage tools. It runs the same feature set in two modes: self-hosted, where you install and maintain the Coolify instance yourself, or Coolify Cloud, where the Coolify team hosts and updates the control plane and you connect your own servers to it over SSH.

That last sentence is the design decision worth internalizing before anything else. Coolify Cloud does not sell compute. Your applications, databases, volumes and secrets stay on servers you control; what you pay the project for is a managed dashboard and control plane. The Cloud control plane itself runs on Hetzner infrastructure in Falkenstein, Germany, and reaches your machines from published IP addresses you can whitelist.

Pricing: what you really pay

The pricing structure is unusually simple. Self-hosted is free forever, with the full feature set: unlimited servers, unlimited deployments, unlimited team members, all current and future features, community support and automated or self-managed updates. The only thing you bring is infrastructure and the time to run it.

Coolify Cloud costs $5 per month as a base price covering two connected servers, plus $3 per month for each additional server. That is the entire commercial surface: no per-seat fees, no per-deployment metering, no credit systems, no add-on SKUs. Teams on Cloud each require their own subscription, which is the one place the flat structure gets less flat. Email alerts for Coolify events are included, support is community plus limited email, and updates are described as founder-tested before rollout.

The total cost of ownership is therefore your server bills plus your ops time. This is where the economics get interesting: because Coolify takes roughly zero margin on compute, a modest European VPS workload that would cost multiples of that on a per-app PaaS stays at whatever your provider charges. In our view, anyone currently paying a managed PaaS fifty to several hundred dollars a month for a handful of small services should do the arithmetic honestly before renewing. The trade-off is real, though, and we get to it below: at $5 per month the support contract is thin, and "community support (20k+ members)" is not the same thing as a support SLA.

One nuance we flag for buyers: the Cloud FAQ asks whether Cloud backs up your application data, and the pricing comparison lists Coolify backups as self-managed on self-hosted and managed on Cloud. Before you treat that as your disaster recovery story, confirm exactly what the managed backup covers — control-plane state versus workload data are different problems.

Performance & infrastructure

Coolify itself imposes very little on performance because it is an orchestrator, not a compute layer. Build and serve speeds are whatever your connected hardware delivers; the platform handles Docker-based builds (images, buildpacks-style flows), health checks, rolling restarts, per-resource limits, and routing through a reverse proxy with automatic TLS. Deployments can be tied to git branches with webhook-driven rebuilds, and the same application workflow applies to databases and one-click services, each with persistent volumes you manage on the host.

Where infrastructure does matter is operational, not raw throughput. Self-hosted mode gives you one control plane to keep alive: it needs its own backups, its own monitoring and its own upgrade discipline. Cloud mode takes that off your plate — the team runs, updates, backs up and monitors the control plane, with built-in high availability for it, and your workload hosts still need OS patching, firewalling and SSH hygiene done by you. Either way, security of the workloads remains your responsibility; Coolify is explicit about that split.

We have not benchmarked Coolify-deployed workloads against managed-PaaS equivalents, so we will not claim parity numbers. What we can say from the deployment model is that the ceiling is set by your server, which is exactly the property that makes cheap dedicated hardware attractive here. If you want reference numbers for the hardware side, our benchmarks cover the VPS classes most people connect to Coolify first.

Community scale is a reasonable proxy for maturity in open source infrastructure, and Coolify's is large: a very active Discord (the pricing page cites 20k+ members), near-daily commits, and hundreds of thousands of self-hosted instances reported by third-party trackers. Third-party counts of GitHub stars and instances vary by source and date — the star figures we saw ranged from roughly 49,000 to over 58,000 — so treat any single number as approximate.

Where it falls short

The honest list starts with responsibility. Coolify moves deployment work off your plate but not ownership: unpatched hosts, exposed SSH ports, misconfigured firewalls and lost volumes are all still yours, and the platform's simplicity can make people forget that. Teams with no Linux generalist on staff are the ones who get hurt by self-hosting, even friendly self-hosting.

Second, this is a fast-moving project rather than a stable enterprise platform. Releases come frequently, upgrades occasionally change behavior, and the issue tracker is busy. That is normal for a project with this velocity and a small core team — Bácsai has built much of it in public as a solo maintainer — but it means you should pin versions, read release notes and keep your own backups rather than assuming smooth sailing between updates.

Third, support and SLA posture is thin by design. There is no uptime commitment for the control plane, no enterprise support tier, no SSO or compliance package of the kind larger organizations get from a Heroku or a Render. If procurement needs a signed SLA, SOC 2 reports or a named support contact, Coolify is not your vendor, at any price.

Finally, Cloud mode keeps some limits worth pricing in: the base subscription covers two servers, additional servers cost $3 per month each, and each team needs its own subscription. None of this is objectionable at these numbers, but the "flat and simple" story does have edges.

Who should pick this

Our pick for solo developers, small teams and homelab-to-production users who have at least one server and want PaaS ergonomics without PaaS pricing. If you run a handful of side projects, client sites or internal tools on a VPS or a dedicated box, and you want push-to-deploy, SSL, databases and service templates handled for you, self-hosted Coolify is close to a free lunch — and Cloud at $5 per month is a fair price for not babysitting the control plane.

We would steer elsewhere two kinds of buyers. First, anyone who needs contractual reliability: pick a managed platform with a published SLA in our managed cloud category instead. Second, non-technical users who want to publish a site without ever seeing a terminal — Coolify is friendly, but it assumes you can administer a Linux host when something breaks at 2 a.m.

Compared with paying per-app PaaS pricing, the saving is usually large and the cost is your own operational attention. Weigh that honestly against the team you actually have.

Key takeaways

• Apache 2.0 open source PaaS, started 2021 by András Bácsai; runs on any Linux host with SSH, from VPS to Raspberry Pi.
• Self-hosted is free forever with every feature — unlimited servers, deployments and team members, no paywall, no enterprise edition.
• Coolify Cloud is $5 per month including two connected servers, plus $3 per month per additional server; it manages the control plane (hosted on Hetzner in Falkenstein), you still bring and secure your own servers.
• Deploys apps, databases and 280+ one-click services with automatic Let's Encrypt TLS and git push workflows.
• No uptime SLA, community-plus-limited-email support, and a fast-moving codebase mean you keep backup and upgrade discipline yourself.
• Best value in managed cloud tooling for teams with Linux skills; wrong fit where procurement demands an SLA or hands-off operations.
