Why it's similar
Libby is the closest and best-loved alternative, with a 4.85 rating across 4,200,000+ reviews, offering free library ebooks and audiobooks plus excellent sync across devices, tagging, customizable reading, and Kindle delivery. Hoopla reviewers themselves repeatedly point to it.
How it differs
Libby uses a hold-and-wait model rather than Hoopla's instant borrowing, so popular titles can mean a 2-3 week queue. It also lacks Hoopla's movies and music, focusing on books and audiobooks, and some users hit occasional CarPlay audio crashes.
