While Spicy itself remains application independent, transparent integration into Zeek has been a primary goal for its development from early on. While historically an external Zeek plugin was required to use Spicy parsers with Zeek, Zeek has now been shipping with built-in Spicy support since version 5.0. That means you can directly add new protocol, file, and packet analyzers to Zeek through Spicy without needing to write any further code. See :zeek:`Zeek's Spicy documentation <devel/spicy/index.html>` for more.
