Quite recently Kin has been open-sourced (see http://blog.kin.today/post/156970937113/kin-is-now-open-source http://blog.kin.today/post/156970937113/kin-is-now-open-sour...).
Have a look at the client (https://github.com/KinToday/kin-web-client https://github.com/KinToday/kin-web-client) and the server (https://github.com/KinToday/kin-api-server https://github.com/KinToday/kin-api-server) on GitHub. It's definitely inspired by Sunrise, but might be a suitable replacement for Google Calendar.
Even better: Contributors get the hosted version of Kin (2€/month; 20€/year) for free.
