Methodology
Same starting URL and page limit. Same Windows environment. Record HTML, CSS, JS, images, fonts, navigation, and notes.
Evidence
How we test WebCopier
A fair test uses the same URL, page limit, and Windows machine, then records what was saved. This page explains the method and internal evidence. It does not invent a public HTTrack bake-off.

Public bake-offNot published
HTTrack vsNot independently tested
What this is not
Not a public scorecard. Not a claim that every JavaScript site succeeds. Legal permission still applies.
Standard methodology
- Same starting URL and page limit
- Same Windows environment and WebCopier 1.4.1
- Compare HTML, CSS, JS, images, fonts, navigation, SPA routes, lazy content
- Record date, missing files, and notes
