Coolify

Overview

Coolify is an open-source self-hosted PaaS started in 2020 by the Hungarian team coolLabs (coolLabs Solutions Kft.), created by lead developer Andras B. as a self-hosted alternative to Heroku, Vercel, and Netlify. Users can deploy websites, APIs, databases, and any Dockerized service with one click on their own cloud servers, keeping all code and data on machines they control.

As of 2026, Coolify reports 491,197+ self-hosted instances running and 3,765+ paying cloud customers, with tens of thousands of GitHub stars. It supports any language and any server (VPS, dedicated servers, even Raspberry Pi), and ships with automatic SSL, reverse proxy, Git integration, and database backups so developers get a complete PaaS experience at minimal cost.

Key Strengths

• Open source with no lock-in: The self-hosted version is completely free under a GPL license; apps and data stay on your own server, and you can migrate away at any time.
• 280+ one-click deploy services: From Node.js, PHP, Python, and static sites to WordPress, n8n, and databases such as MySQL, PostgreSQL, Redis, and MongoDB, all deployable from the UI — pair it with the Docker deployment guide to get started fast.
• Automatic SSL and reverse proxy: Custom domains get automatic Let's Encrypt certificates (90-day validity) with built-in Nginx/Traefik reverse proxy, removing manual HTTPS configuration.
• Git-based continuous deployment: Integrates GitHub, GitLab, Bitbucket, and Gitea; push to deploy with isolated Pull Request previews, as covered in the Git deploy workflow.
• Automatic database backups: Daily backups to any S3-compatible storage with one-click restore, complementing a solid server backup strategy.

Product Ecosystem

One-Click Service Library

Coolify ships 280+ one-click deploy templates covering application frameworks (Node.js, PHP, Python, Go), static sites, WordPress, CMS platforms, and self-hosted SaaS components such as n8n, letting you go live without writing a Dockerfile.

Database Management

One-click creation and backup for MySQL, PostgreSQL, MariaDB, Redis, MongoDB, and ClickHouse, with automatic linking to application instances and built-in backup and restore.

Reverse Proxy and SSL

Built-in Nginx and Traefik reverse proxy automatically issue Let's Encrypt certificates per domain, handle HTTP/HTTPS redirects and WebSocket support, and route traffic when multiple apps share one server.

Deployment API and Webhooks

A REST API and webhook support integrate with CI/CD pipelines such as GitHub Actions and GitLab CI for automated deployment and resource management.

Coolify Cloud (Managed)

For teams that prefer not to run their own server, Coolify Cloud bills by compute resources and offers the same deploy experience without the operations overhead.

Limitations

• You own the operations: Monitoring, alerting, and team permissions are weaker than commercial PaaS, and you maintain the OS and runtime yourself, shifting the operational burden to your team.
• Limited multi-server orchestration: High availability and multi-node orchestration are weak, so app availability depends on the host machine; large production workloads usually add Kubernetes on top.
• Fast release cadence: Frequent releases occasionally include breaking changes, so snapshot backups are recommended before major upgrades to protect live deployments.
• No enterprise capabilities: There is no SLA, enterprise auditing, or 24/7 human support, which is a poor fit for compliance-sensitive or vendor-backed teams.

Use Cases

• Individual / indie developers (★★★★★): Free self-hosting — a cheap 2-core 4GB cloud server can host all of your personal projects.
• Internal tools for small teams (★★★★): Deploy n8n, WordPress, API services, and other internal apps for a fraction of SaaS subscription costs.
• Budget-conscious startups (★★★★): Build your own PaaS along the lines of low-cost cloud spending control and avoid per-seat pricing.
• Businesses needing SLA and managed ops (★★): No human support or SLA; mission-critical workloads are better on a managed PaaS or with professional operations.

Pricing

Note: The self-hosted version has no feature limits — you only pay for server hardware and bandwidth; Cloud pricing varies by configuration and the official site offers live estimates.

FAQ

• How is Coolify different from Vercel or Heroku? Coolify is self-hosted — apps run on your own server and data stays fully under your control; Vercel/Heroku are managed PaaS billed by usage but need no operations. Teams that are budget-sensitive or care about data sovereignty fit Coolify best.; see Docker deployment basics.

• What hardware does self-hosted Coolify need? The official recommendation is at least 2 cores and 2GB of RAM; with real workloads, start from 2 cores and 4GB. A Docker environment is required — see the Docker deployment guide for beginners.

• Does the free version have limits? No. The self-hosted edition has no feature limits — unlimited apps, unlimited domains, auto SSL, and database backups are all free; only Coolify Cloud bills by resources.; see cloud cost control for small sites.

• Can Coolify deploy WordPress? Yes. Coolify includes a WordPress one-click template that configures the reverse proxy, SSL, and database automatically; the WordPress hosting market analysis helps you estimate deployment costs.

• Is my data safe with Coolify? Data lives on your own server with daily automatic backups to S3-compatible storage. Follow the server backup strategy for off-site copies.
