Coolify

Overview

Coolify is a powerful, open-source platform that functions as a self-hosted Heroku or Vercel alternative. It allows users to easily deploy, manage, and scale a wide variety of web applications—including n8n, WordPress, and Ghost—on a single Virtual Private Server (VPS). By simplifying the deployment pipeline and infrastructure management, Coolify significantly reduces hosting costs while providing complete control over your apps and data.

Key Concepts

• Cost-Effective Self-Hosting: Host multiple applications, services, and databases securely on a single affordable VPS using Coolify's built-in proxy and wildcard domain routing.
• Pre-Built Deployments: Coolify provides out-of-the-box templates that drastically simplify the installation of complex stacks (like n8n with Postgres) compared to manual Docker configuration.
• Robust Security: The setup relies on SSH key authentication and strict firewall configurations (blocking unused ports) to ensure your self-hosted infrastructure remains safe.
• Scalable Architecture: Easily scale from a single-server setup to a multi-server environment where a central Coolify control server manages deployments across dedicated worker nodes.
• Maintenance & Backups: Regularly backing up your data (e.g., using UpdraftPlus for WordPress or backing up Docker volumes) is critical before leveraging Coolify's redeploy feature to update applications.
