Developers implementing an OPDS catalog usually use the Feedbooks catalog<ref>{{cite web |url=http://www.feedbooks.com/catalog.atom |title=Feedbooks OPDS Catalog |publisher=Feedbooks |date= |accessdate=2011-05-19}}</ref> as an example of a fully featured catalog. An OPDS validator is also available to test OPDS feeds.<ref>{{cite web |url=https://opds-validator.appspot.com/ |title=OPDS Validator |accessdate=2011-05-19}}</ref>

Over a dozen OPDS clients are available on major platforms such as [[Android (operating system)|Android]], [[iOS]] and [[Microsoft Windows|Windows]].<ref>{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#eBook_Reading_Software_Supporting_OPDS |title=eBook Reading Software Supporting OPDS |publisher=MobileRead Wiki |date= |accessdate=2011-05-15}}</ref>
