To self-host Coolify, rent a fresh Linux VPS with SSH access, then run Coolify’s installer on it. Coolify’s documented minimum is 2 CPU cores, 2 GB RAM and 10 GB of free disk, but that is the platform minimum—not a reliable size for every app. Choose extra capacity for your deployments, databases, builds, Docker images and backups.
Decide what the VPS will run
Coolify is a control plane: it connects to servers over SSH and coordinates deployments, domains, HTTPS, health checks and related operations. With a self-managed installation, you run the control plane on infrastructure you manage; you also remain responsible for the server operating system, firewall, application and database data, backups and recovery. Coolify’s overview explains the platform’s role.
There are two separate capacity decisions: where Coolify’s dashboard runs, and where your production applications run. A self-hosted installation starts with a localhost server, which can run both Coolify and your deployments. That is convenient for a first deployment, but builds and applications share resources with the dashboard. For production workloads, consider connecting a remote server so app activity is less likely to affect the control plane. A dedicated build server is another option if builds need their own resources. See Coolify’s server overview.
Choose a VPS size and Linux image
Coolify’s self-hosted setup guide lists a minimum of 2 CPU cores, 2 GB RAM and 10 GB free disk, with amd64 and arm64 supported. These figures describe what Coolify needs to run; they do not guarantee that a particular workload will perform well. Build jobs, running apps, databases, Docker images, persistent volumes and backups all compete for the same resources when they share a machine.

- WHY CHOOSE G3 ULTRA MINI PC PENTIUM GOLD 7505 - Choose the Intel Pentium Gold 7505 for snappier everyday responsiveness: It delivers up to 30% faster single-core performance than the Ryzen 5 3500U, making office apps and web browsing feel noticeably quicker, while its Intel UHD Graphics (48 EUs) provides 2.4x the GPU performance of the N100 & N150's 24-EU graphics, ensuring smoother 4K streaming and light photo editing.
- 16GB RAM MEMORY & 512GB STORAGE - GMKtec Nucbox G3 Ultra mini computer is prebuilt with 16GB LPDDR4 RAM at 3200 MT/s, you will enjoy a speedier experience with Built-in 512GB M.2 SATA Hard Drive. Our mini desktop pc boots up in seconds, work on multiple browser tabs, software applications and quickly transfers files. There is a primary slot and secondary expansion storage. Primary slot is M.2 2280 PCIE and secondary slot is M.2 2280 SATA.
- RICH INTERFACE - Nucbox pentium mini computer is equipped with 3* USB 3.2 Gen2 ports, up to 10Gbps/S, 1*USB 2.0, HDMI(4K@60Hz)*2, 3.5mm Audio Jack. Supports WiFi 6, and Gigabit Ethernet RJ45 2.5GbE network connectivity, Bluetooth 5.2. This Mini PC supports multiple device connection and can be used with servers, monitoring equipment, office equipment, displays, projectors, televisions, etc.
- 4K DUAL SCREEN DISPLAY - Mini desktop computer is equipped with upgraded Intel Graphics(max 1000MHz), supports 4K video playback and AV1 decoding, connect the pc with a projector as a home theatre, enjoy a variety of entertainments. Two HDMI 2.0 ports allows you to multi-task efficiently on two 4K@60Hz displays.
- UPGRADED COOLING FAN - The G3 Ultra has upgraded the cooling fan to reduce fan noise and thermals. We are using an upgraded thermal paste as well to help reduce heat on the CPU.
Coolify says smaller machines can run the platform but are not recommended. High resource use from builds and deployments can make a shared server unresponsive. For a sense of how workload-specific sizing is, Coolify gives one example: a Hetzner CAX11 with 2 vCPU, 4 GB RAM and 40 GB storage reportedly averaged 2.6 GB RAM, 60–70% CPU and 32 GB storage for a heavily optimized workload that built externally. Treat that as a single published example, not a benchmark or a general recommendation.
A fresh server is recommended to reduce conflicts. Before ordering, check Coolify’s current supported operating systems table against the image offered by your provider. It includes Debian and Ubuntu, Red Hat- and SUSE-family systems, Arch, Alpine and 64-bit Raspberry Pi OS. The guide notes that Ubuntu non-LTS may require manual installation, some variants may require Docker to be installed manually, and Raspberry Pi OS requires arm64.
Choose a provider and understand the bill
Coolify’s documented provider-provisioning flow supports Hetzner, DigitalOcean and Vultr. You can also provision a compatible Linux server elsewhere and connect it, provided you have the access needed to install and manage it. The integration list is not a guarantee that a particular plan, image or location is available today.
Free tools Windows power users keep installed
One-click scans. No signup required.
Before purchase, compare the region, server resources, Linux image, SSH access and total recurring cost. Provider prices, regions, plan specifications and optional fees can change, so verify them at checkout. Coolify’s provisioning guide specifically notes that Hetzner backups add 20% to the monthly server price; confirm the current fee before enabling that option.

Self-hosted Coolify software and VPS hosting are separate costs. Coolify’s pricing page listed self-hosted as free and Coolify Cloud starting at $5 per month for two connected servers when checked on October 7, 2026. Cloud manages the control plane but does not supply the workload servers. Recheck the pricing page before deciding, since pricing can change.
Provision the VPS through Coolify or your provider
Coolify’s documented cloud provisioning workflow requires a provider account able to create servers, a provider cloud token, a private SSH key configured in Coolify, and a valid payment method with the provider. The form asks you to choose a server name, location, plan or resources, supported Linux image and private key. Exact choices depend on the provider and its current offerings.
-
Create or select the provider account and confirm that its payment method is valid. Generate a provider token with the permissions needed to create servers, and configure your SSH private key in Coolify.

Securely back up
/data/coolify/source/.env. It contains installation secrets, includingAPP_KEY, which is used to encrypt Coolify database values and is needed for restoration. Store the backup somewhere protected and separate from the VPS. -
Confirm that the proxy is running, then make a low-risk test deployment. Coolify’s first-app guide uses an Nginx Docker image and a generated test domain to check the deployment path.
Check the setup before relying on it
-
Confirm you can still connect over SSH and that firewall rules allow only the access your setup needs.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy. -
Sign in to the Coolify dashboard and verify the server is reachable and the proxy is running.
-
Deploy a simple test app before moving production workloads. Watch CPU, memory and disk use during builds and while the app runs; add capacity or separate workloads if the server is under pressure.
-
Keep protected copies of application and database backups as well as Coolify’s
.envfile. A VPS alone does not provide a recovery plan.Quick Recap
