As answered by people managing HackerRank and epuBear.
epuBear's answer:
epuBear stands out by combining a free EPUB reader app with a cross-platform SDK for custom ebook solutions. It supports EPUB2/EPUB3, parsing, rendering, navigation, multilingual content, and customizable reading modes, helping teams add EPUB functionality without building a reader engine from scratch.
epuBear SDK is especially useful for teams that need not only a standalone EPUB reader, but also a flexible technical foundation for branded ebook apps, digital libraries, EdTech platforms, and publishing products.
