- They diverge on capability: HTMX covers AJAX requests, Read the Docs covers Build on commit.

- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
