Large PDFs are very slow in browsers. I believe they all use pdf.js (or similar).

PDFkit seems to be a name a few different things in stuff like node and ruby. I think the Apple PDFkit is probably just wrapping Apple’s in house PDF tech that Preview uses?
the pdfkit from the first google result doesn't seem to be related to apple's. what happened here is that "pdfkit" is a very generic name (that will tend to show up because people love writing pdf-related software) that also happens to coincide with apple's convention of naming their frameworks something-kit (uikit, appkit, avkit, ...)
firefox uses pdf.js, but chromium uses pdfium and safari uses pdfkit
