In the ever-evolving world of web servers, Caddy has emerged as a game-changer. Designed for simplicity and modern workflows, it offers automatic HTTPS, straightforward configuration, and a developer-friendly approach.
What is Caddy Server?
Caddy is a modern, open-source web server written in Go. It’s known for its ability to handle complex web hosting tasks effortlessly. Whether you’re hosting a static site, reverse proxying APIs, or managing secure connections, Caddy simplifies the process with features like:
- Automatic HTTPS: Get secure connections by default using Let's Encrypt.
- Readable Configs: Manage sites with a simple Caddyfile—no cryptic syntax required.
- Built-in Reverse Proxy: Handle API routing and load balancing without extra tools.
Why Choose Caddy?
Compared to traditional servers like Apache and Nginx, Caddy is:
- Easier to Use: Minimal setup and automatic configurations.
- Secure by Default: HTTPS is enabled automatically.
- Lightweight Yet Powerful: Written in Go for speed and scalability.
Quick Setup
Download the version according to your OS -> https://caddyserver.com/download
Create a Caddyfile in your server's directory.
# Example Caddyfile
localhost {
reverse_proxy localhost:8080
}
- Start the Server:
-
sudo caddy start-> to run the server in the background -
sudo caddy stop-> to stop the background running caddy server -
sudo caddy run-> to run the server in foreground
-
When to Use Caddy?
- Static Websites: Host portfolios, blogs, or landing pages with ease.
- APIs and Microservices: Use built-in reverse proxying for seamless API management.
- HTTPS Needs: Say goodbye to manual SSL certificate management.
Quick Example:
// app.js
const express = require('express');
const app = express();
const port = 8080;
app.get('/', (req, res) => {
res.send('Hello from Express server!');
});
app.listen(port, () => {
console.log(`Server is running on http://localhost:${port}`);
});
# Caddyfile
localhost {
reverse_proxy localhost:8080
}
node app.js -> This will start your actual backend server in 8080 PORT
sudo caddy run -> This will start the caddy server and you will be able to handle all requests at localhost:443
Extra tips
- For Linux, once you get the binary from official site, you can rename that to "caddy" and then move the file to "/usr/local/bin/"
- Then change the permissions.
sudo chmod ugoa+x caddy - Then you will be able to access "caddy" via CLI anywhere in your system
Conclusion
Caddy server is perfect for developers looking for a modern, no-hassle web server. Whether you’re a beginner or a seasoned professional, its features and simplicity make it an excellent choice for most projects.

Caddy does seem like an interesting choice for modern workflows, but I’m curious—how does it handle scaling or high-traffic scenarios compared to Nginx or more traditional setups such as Cloudways Stack based on Apache and Nginx? Also, what’s your experience with resource utilization when using Caddy for reverse proxying heavy APIs?
It benefits from Go's memory management, making it an excellent choice for reverse proxying heavy APIs with many concurrent connections.
