I use Google Analytics, Flurry Analytics, Facebook Analytics and Fabric all with custom events. Fabric is great for real-time. Mixpanel seems to be extremely costly depending on what type of app or game you have.

For broadcast push notifications, I use PushWoosh. They have a lot of features that Parse Push doesn't for broadcast notifications.

As for the in-app client-based push notification triggered by liking or commenting on a post or profile, I have no idea how to replace that without Parse. Hopefully they'll included some sort of guide to help with that migration.
