A Caddyfile is the main configuration file for the Caddy web server. It uses a simple, block-based syntax to define how your server should handle requests, manage domains, and apply directives like reverse proxies or compression.

How do I use the generated Caddyfile?

Copy the generated code and save it to a file named 'Caddyfile' (no extension) in the same directory as your Caddy executable. Then run 'caddy run' or 'caddy reload' in your terminal.

Does Caddy support automatic HTTPS?

Yes! Caddy is famous for being the first web server to have HTTPS on by default. It automatically obtains and renews certificates from Let's Encrypt for any domain names in your Caddyfile.

About Caddyfile Generator

The Caddyfile Generator is a powerful, free online tool designed to help developers and system administrators create configuration files for the Caddy Web Server. Whether you are setting up a simple static site, a complex reverse proxy, or a WordPress installation, this tool simplifies the process by providing a visual interface for common directives.

Caddy is known for its simplicity and automatic HTTPS. However, remembering the exact syntax for every directive can be challenging. This tool bridges that gap, ensuring your configuration is syntactically correct and optimized for performance.

How to Use This Tool

Select a Recipe: Choose your project type (e.g., Static Site, Reverse Proxy) to pre-load standard settings.
Enter Domain: Input your domain name(s). Use localhost for local development.
Configure Paths: Set your site root or upstream proxy address depending on your recipe.
Toggle Features: Enable compression, logging, or security headers with a single click.
Export: Copy the code to your clipboard or download the Caddyfile directly.

Tips for Caddy Users

Automatic HTTPS: Caddy automatically provisions TLS certificates from Let's Encrypt. Ensure your domain's DNS records point to your server before starting Caddy.
Formatting: Use the caddy fmt command in your terminal to automatically format your Caddyfile if you make manual edits later.
Reloading: You don't need to stop the server to apply changes. Run caddy reload for zero-downtime configuration updates.
