OpenKit, the open-source successor of OpenFeint, is now live

OpenKit, the open-source followup of recently shuttered leaderboard and social feature provider OpenFeint, officially went live today for developers. Conceived as a full successor to OpenFeint, OpenKit offers support for Apple's Game Center, Google + and Facebook, to allow cross-platform social features including social leaderboards, push notifications, asynchronous multiplayer, and tools for in-app purchases. Described as an "open-source, freemium" platform, the service is free to install and tailor on developers' own backends. If used through OpenKit's webspace, the service is free up to a given monthly active user (MAU) count, after which developers can opt for a subscription. "We're breaking down the silos of vertical services that come with mobile platforms," the OpenKit co-founders said in conjunction with the announcement. "Developers can seamlessly slide in OpenKit which wraps both Game Center APIs and Google Play Services." OpenKit was first revealed at March's Game Developers Conference held in San Francisco. At the time, OpenFeint co-founder Peter Relan added that OpenKit would provide "free assistance and full service migration services" to developers wishing to switch to the open-source platform.
