unicode-range-split
Split a CJK font in two: the glyphs you use, and the rest
A CJK typeface is megabytes because it covers everything. unicode-range-split splits a font into two files: the characters your site actually uses, and everything else, with no glyph dropped. Ordinary pages fetch the small file; the other waits behind a unicode-range until a page uses a character from it. On its own demo, every page fetches 125 KiB instead of 5,632 KiB. Unlike subsetting, a rare kanji in someone's name still renders in your typeface. Free and open source.
Hi Product Hunt! Subsetting a Japanese font to the characters you use today works until someone's name has a kanji nobody wrote before, and then one glyph falls back to a different face. unicode-range-split keeps every glyph but makes ordinary pages fetch only the common ones. The demo site uses the two files it produced; type a rare kanji and watch the second file load. Feedback welcome!
