Nginx Config Formatter & Beautifier

Nginx Config Formatter & Beautifier

Format and beautify Nginx configuration files with consistent indentation, block nesting, and syntax validation. Paste your nginx.conf content and instantly see properly formatted output with a structural overview of your server blocks, locations, and upstreams. Includes common snippet templates and a directive reference.

Anwendung

Paste your Nginx configuration into the input area. The formatter processes it instantly — indenting block directives (http, server, location, upstream, events, map, geo, if), normalizing comments, and validating syntax. Configure indent style (2 spaces, 4 spaces, or tabs), brace positioning, comment normalization, and blank line handling. View the structure tree to understand your config hierarchy. Copy the formatted output or download as nginx.conf.

Merkmale

• Block Indentation — Automatically indents nested directives inside http, server, location, upstream, events, map, geo, if, types, limit_except, and other Nginx block directives.
• Strukturansicht — Tree/outline of your config hierarchy: http → server (with server_name and listen port) → location paths, upstream names. Helps visualize complex multi-server configurations at a glance.
• Syntaxvalidierung — Detects unclosed braces, extra closing braces, missing semicolons on directive lines, duplicate server_name values, and common misconfigurations. Color-coded with line numbers.
• Formatting Options — Configurable indent style (2/4 spaces, tabs), brace style (same line or next line), comment normalization, blank line collapsing, semicolon spacing.
• Common Snippets — Quick-insert templates: reverse proxy, static file serving, SSL/TLS, rate limiting, gzip compression, security headers, PHP-FPM fastcgi, WebSocket proxy.
• Directive Reference — Collapsible reference with common Nginx directives, block types, and location matching rules (exact, prefix, regex).
• Exportieren — Copy formatted output or download as nginx.conf file.

Nginx Block Types

http: Main context for HTTP server configuration. server: Defines a virtual host — identified by server_name and listen directives. location: Maps URI patterns to configuration — supports exact match (=), prefix (^~), regex (~, ~*), and default matching. upstream: Defines a group of backend servers for load balancing. events: Connection processing configuration. map/geo: Variable mapping blocks for conditional configuration.
