Nokolexbor

Nokolexbor is a drop-in replacement for Nokogiri. It's 4.7x faster at parsing HTML and up to 1352x faster at CSS selectors.

It's a performance-focused HTML5 parser for Ruby based on Lexbor. It supports both CSS selectors and XPath. Nokolexbor's API is designed to be 1:1 compatible as much as possible with Nokogiri's API.
