With the death of Google Reader under a month away, third-party RSS clients will soon need to find a replacement to Google’s service. Feedly has been working hard to fill the void, and it’s announcing that it will integrate with the apps Reeder, Nextgen Reader, gReader, Press, and Newsify before the end of the month. To ease the transition for developers, Feedly has been turning its API into a clone of Reader’s. It’s also been working with those five apps’ developers to make third-party integration even more robust. That should also make it easier for apps that aren’t on that list to hook into Feedly as well. Because Reader was the go-to service, it shouldn’t be hard for other apps to support Feedly if it really can create a replica of Google’s API. But Feedly isn’t just leaving app development up to the community — it’s going to be beefing up its own services as well.
