Why people look for alternatives to Books
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Catalog coverage is uneven and some download links go stale over time
- No built-in reader, annotation, or bookmarking tools — raw file access only
- Performance and uptime depend on Streamlit's free hosting tier
- No dedicated support channel; unresolved GitHub issues linger for months
