Aim is to replace gzip when it comes to HTTP(S) web compression. Major browsers already support it, but only over a TLS/SSL connection. The compression speed is not so great, but brolti compressed content will be smaller then with gzip.
Brotli can also be used as a standalone compressor.
git clone https://github.com/google/brotli.git
mkdir out && cd out
Installation NGINX + Brotli
After installation you need to activate Brotli compriossion in
# Brotli compression
Besides the new header, I don't see a significant performance improvement compared to good old gzip/deflate.
