Como gerar configurações Nginx

1Escolha um modelo: Reverse Proxy, SPA (React/Vue), Site Estático ou PHP-FPM.
2Informe seu nome de domínio e a porta upstream do servidor backend.
3Ative as opções de SSL/HTTPS, HTTP/2, WebSocket e compressão Gzip.
4Copie a configuração ou baixe o arquivo .conf para o seu servidor.

Segurança e Isolamento Local

Seus IPs privados e nomes de domínio internos nunca saem da sua máquina.

Arquitetura e Privacidade

100% Client-Side Generator: Zero server uploads. Internal server IPs, private domains, and path structures remain strictly within your local browser memory.
Battle-Tested Best Practices: Mozilla Modern TLS ciphers, HSTS headers, secure session caching, and protection against dot-file exposure (.git, .env).
Full WebSocket Proxy Support: Automatically injects Upgrade and Connection headers for Socket.io, GraphQL subscriptions, and real-time streams.
SPA History Mode Routing: Ready-to-use try_files $uri $uri/ /index.html fallback for client-side routing in React, Vue, Angular, and Svelte.
