FBReader was originally written by Nikolay Pultsin and released for the Sharp Zaurus in January 2005, a Maemo port was added in December 2005 for the Nokia 770. FBReader has since had binary packages released for many mobile device platforms and most major personal computer (PC) operating systems.[3] The FBReader name with the FB prefix comes from FictionBook, an e-book format which is popular in Russia, the country of FBReader's author.[4]

The original FBReader was written in C++, however in 2007[5] a fork called FBReaderJ was created, which was written in Java. As the Android platform became available in the following years, this fork became the codebase for the android app, which the C++ codebase remained in use for the other platforms.[6]


For easy cross-platform compiling, FBReader uses zlibrary, a cross-platform interface library. It allows recompiling for many platforms while disregarding the GUI-toolkit used.
