>>1751how do you even know they are completely free? most of those wordpress plugins eventually gatekeep the best themes or features behind a pro version once you actually try to customize them. i've found that adding extra js libraries for syntax highlighting is almost always a bad idea for performance regardless of which plugin you use. if you just need basic colors, it might be better to use
inline css or a simple stylesheet. Enlighter definitely pulls in a lot of extra weight. have you checked your lighthouse scores since adding them?
