Who Should Use This Tool?

DevOps Engineers & Sysadmins

Quickly format NGINX configs from production servers for better readability, debugging, and documentation.

Full-Stack & Backend Developers

Format generated or auto-migrated NGINX configs to understand server behavior without spending time manually indenting.

DevOps Teams & SREs

Standardize config formatting across your infrastructure before code reviews and Git commits.

Why this is better than manual formatting: Saves hours of tedious manual work, eliminates inconsistent indentation, and ensures configs are readable in seconds instead of hours.

Before & After Example

Before (messy, hard to read)

server{listen 80 default_server;server_name example.com www.example.com;root /var/www/html;index index.html; location / {try_files $uri $uri/ /index.html;} location ~ \.php$ {fastcgi_pass unix:/run/php/php8.1-fpm.sock;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;} location /api {proxy_pass http://127.0.0.1:3000;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}}

After (clean & readable)

server { listen 80 default_server; server_name example.com www.example.com; root /var/www/html; index index.html; location / { try_files $uri $uri/ /index.html; } location ~ \.php$ { fastcgi_pass unix:/run/php/php8.1-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location /api { proxy_pass http://127.0.0.1:3000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }

How It Works

Copy your NGINX config and paste it into the input area.

2. Customize

Choose indentation style (spaces/tabs) and bracket placement.

Power User Tips

💡 Tip 1: Use Consistent Indentation

Stick to either spaces or tabs throughout your config. Pick spaces (2-4) for portability or tabs for accessibility.

💡 Tip 2: Copy Before Beautifying

Always keep a backup of your original config. While beautifier won't modify logic, it's good practice.

💡 Tip 3: Validate on Server

After formatting, run nginx -t on your server to ensure syntax is still valid.

Common Mistake: Don't assume beautified = valid. The formatter improves readability but doesn't validate NGINX syntax. Always test configs before deploying.
