Reverse Proxies

PostgSail can run without a reverse proxy. Hosting PostgSail behind a reverse proxy can help with security, scalability, and flexibility.

Doing so has a few downsides:

• PostgSail does not support HTTPS connections natively (TLS termination must be handled by the proxy).
• PostgREST does not check HOST headers — it serves on a port regardless of the hostname used. A reverse proxy lets you enforce correct hostname routing.
• PostgREST only supports simple in-memory caching. If you need more advanced caching, use a reverse proxy like Nginx, Varnish, or Apache with custom rules.
• You may need to host multiple services (API, frontend, Grafana) under a single domain or set of subdomains.
