Coolify is a self-hosting platform for deploying containerized applications cost-effectively, providing more control compared to cloud hosting services. While Coolify offers convenience, it requires added security measures. This guide details how to secure a Coolify instance with Tailscale, which limits server access to a private network. It includes steps to install and configure Tailscale, set up a firewall with UFW, and deploy a Next.js application. Additional focus is placed on best practices like input validation, authentication, and maintaining regular updates to secure the application further.
