Caddy vs. Nginx in 2025: Differences for Educational Platforms

🔍 Introduction: Caddy vs. Nginx for Education in 2025

In 2025, web servers like Nginx (35% market share) and Caddy (30% adoption among modern servers) power educational platforms on Amazon EC2 Ubuntu, fueling India’s 35% EdTech growth (NASSCOM). Caddy’s automatic HTTPS and simplicity contrast with Nginx’s high performance and flexibility. This guide compares their differences—configuration, HTTPS, performance, and more—while deploying a Next.js frontend and Python/FastAPI backend for a course dashboard in ap-south-1 at ₹0.80/hour. Replace yourdomain.com with your domain or public IP. Build on our EC2 Node.js and Caddy guide and explore crypto education trends in RBI’s repo rate impact on crypto.

🚀 Caddy vs. Nginx: Key Differences

1. Configuration

- Caddy: Uses a human-readable Caddyfile, e.g., reverse_proxy /api/* localhost:8000. Ideal for beginners.

- Nginx: Requires complex .conf files, e.g., proxy_pass http://localhost:8000;. Steeper learning curve.

🧩 Use Case: A Bengaluru educator chooses Caddy for quick setup, saving 2 hours vs. Nginx.

2. HTTPS

- Caddy: Automatic Let’s Encrypt integration, no setup needed.

- Nginx: Manual setup with Certbot or custom certificates.

🔒 Benefit: Caddy reduces setup time by 30 minutes.

3. Performance

- Caddy: Handles ~10,000 req/s on t2.micro, suitable for small/medium platforms.

- Nginx: Scales to ~50,000 req/s, ideal for high-traffic sites.

📈 Impact: Nginx suits 10,000+ daily users (Stack Overflow).

4. Security Headers

- Caddy: Simple header directive, e.g., Strict-Transport-Security.

- Nginx: Flexible add_header, but requires manual tuning.

🧩 Use Case: A Mumbai startup uses Caddy’s headers, cutting config time by 20%.

5. Extensibility

- Caddy: Limited modules, but growing ecosystem.

- Nginx: Vast module support, e.g., Lua, GeoIP.

🔗 Benefit: Nginx supports complex routing for 15,000 users.

🛠️ Step-by-Step: Deploying with Caddy and Nginx

Deploy a course dashboard on EC2 Ubuntu using Caddy or Nginx.

1. Launch EC2 Instance

- Name: “Caddy-Nginx-Education”

- AMI: Ubuntu Server 20.04 LTS.

- Type: t2.micro.

- Key Pair: Create “edu-key.pem” (chmod 400 edu-key.pem).

- Network: Public IP, allow SSH (22), HTTP (80), HTTPS (443).

- Storage: 8 GB SSD.

Note public IP (e.g., 54.123.45.67).

2. Install Dependencies

SSH: ssh -i edu-key.pem ubuntu@ and update: sudo apt update && sudo apt upgrade -y.

Install Python, Node.js, Nginx, Caddy:

sudo apt install -y python3 python3-pip nodejs npm nginx
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install -y nodejs
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf "https://dl.cloudsmith.io/public/caddy/stable/gpg.key" | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf "https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt" | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update && sudo apt install caddy

3. Set Up Python Backend (FastAPI)

Create backend:

mkdir edu-backend && cd edu-backend
pip install fastapi uvicorn
pip freeze > requirements.txt

Create main.py:

from fastapi import FastAPI
app = FastAPI()\[email protected]("/courses")
async def get_courses():
return [{"id": 1, "title": "Python 101"}, {"id": 2, "title": "Math 101"}]

Test: uvicorn main:app --host 0.0.0.0 --port 8000.

4. Set Up Next.js Frontend

Locally, create frontend:

npx create-next-app@latest edu-frontend
cd edu-frontend
npm install axios

Edit pages/index.js:

import { useState, useEffect } from "react";
import axios from "axios";
export default function Home() {
  const [courses, setCourses] = useState([]);
  useEffect(() => {
    axios.get("/api/courses")
.then(res => setCourses(res.data));
  }, []); 
 return (  Course Dashboard    {courses.map(c => {c.title})} );
}

Export: npm run build && npm run export.

5. Caddy Simple Configuration

Edit /etc/caddy/Caddyfile:

yourdomain.com {  reverse_proxy /api/* localhost:8000  root * /home/ubuntu/edu-frontend/out  file_server}

Transfer frontend: scp -i edu-key.pem -r out ubuntu@:/home/ubuntu/edu-frontend/.

Reload: sudo systemctl reload caddy.

6. Nginx Simple Configuration

Edit /etc/nginx/sites-available/default:

Run sudo certbot --nginx -d yourdomain.com for HTTPS.

server {  
listen 80;
server_name yourdomain.com;
location / { 
root /home/ubuntu/edu-frontend/out;    
try_files $uri $uri/ /index.html;
  }  
location /api/ {    
proxy_pass http://localhost:8000/;    
proxy_set_header Host $host;
  }
}

Install Certbot: sudo apt install certbot python3-certbot-nginx.

Transfer frontend: scp -i edu-key.pem -r out ubuntu@:/home/ubuntu/edu-frontend/.

Test: sudo nginx -t and reload: sudo systemctl reload nginx.

7. Deploy Backend

Transfer: scp -i edu-key.pem -r edu-backend ubuntu@:/home/ubuntu/.

Install: cd /home/ubuntu/edu-backend; pip install -r requirements.txt.

Install PM2: sudo npm install -g pm2.

Start: pm2 start "uvicorn main:app --host 0.0.0.0 --port 8000" --name backend.
