Is this a production-ready Nginx config?
No. It is a best-effort generator, so you should review and adjust the output before using it in production.

Nginx Reverse Proxy Generator
Generate Nginx reverse proxy server blocks for self-hosted apps, Docker services, WebSocket apps, and HTTPS setups in your browser.
Example output
server {
listen 80;
server_name example.com;
location / {
client_max_body_size 50m;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://127.0.0.1:3000;
proxy_redirect off;

More context for Nginx Reverse Proxy Generator
Useful when you want a fast starting point for a reverse proxy without hand-writing every directive, especially for a Docker-backed app.
Overview
What is this tool?
It generates Nginx reverse proxy server blocks in your browser from a domain, upstream target, and optional toggles for WebSocket support, common proxy headers, HTTPS templates, and HTTP-to-HTTPS redirects.
Input samples
Example inputs
Basic reverse proxy
domain: example.com upstream: http://127.0.0.1:3000 common proxy headers: on websocket support: off
WebSocket app
domain: app.example.com upstream: http://app:8080 common proxy headers: on websocket support: on client_max_body_size: 100m
HTTPS and redirect
domain: app.example.com upstream: https://127.0.0.1:8443 common proxy headers: on websocket support: on redirect block: on SSL template: on
When to use it
Common use cases
- Create a reverse proxy starter config for a self-hosted app or Docker service.
- Add WebSocket support and common proxy headers without memorizing every directive.
- Generate a clean HTTPS template with placeholder certificate paths before you request or decode a real certificate.

Answers
FAQ
Does it support HTTPS upstreams?
Yes. Select https as the upstream protocol and the generated proxy_pass line will use an https upstream URL.
Will it use my real SSL certificate paths?
It uses placeholder paths based on the domain you enter. Adjust the certificate files, server names, and upstream address to match your environment.
What should I check after generating the proxy?
Review the upstream host, port, headers, TLS paths, and redirect block, then verify the response with the header tools.

This is a best-effort config generator, not a replacement for hands-on review. Check the generated output before production use and adjust the SSL certificate paths, real domain names, upstream service address, and any environment-specific directives to fit your setup.
