## What it is
A set of two NGINX modules that add Brotli compression support: one compresses HTTP responses on-the-fly and the other serves pre-compressed static files. It is written in C and maintained by Google under a BSD-2-Clause license.

## Use cases
- serve brotli-compressed responses from nginx
- compress http responses on the fly with brotli
- serve pre-compressed .br static files
- reduce bandwidth for web assets
- replace gzip with better compression in nginx

## When to choose
- you run NGINX and want better compression ratios than gzip
- you want to serve pre-compressed static assets to browsers supporting Brotli

## When to avoid
- you use a web server other than NGINX
- you cannot recompile NGINX with third-party modules
- your clients or proxies do not support Brotli encoding
