GitBook
- Hosted, so you do not own the rendering pipeline and are subject to platform changes
- Git sync is powerful but conflicts between browser and repository edits are confusing to resolve
- Pricing scales per user, which gets expensive where many people contribute occasionally
- Less customisable than a static site generator you control end to end
HTMX
- Best suited for server-rendered architectures, not pure client-side SPAs
- Limited client-side state management capabilities compared to frameworks
- Smaller ecosystem with fewer third-party libraries and tools
- Learning curve for developers from JavaScript framework backgrounds
