Ask HN: Alternatives to Mixpannel

We are an early-stage startup with 4 million active users. We have been using Mixpannel for two years now. It has worked beautifully for us to understand event funnels and has helped us in product decisions and understanding user behaviours.

Lately, due to the high volume of events fired, it has become quite expensive for us to afford.

I am looking for some open-source alternatives we can deploy in our cloud.

Features that I am looking out for are:

1. Funnel analysis like Mixpannel 2. User events like Mixpannel 3. Simple UI to understand and create funnels. 4. Near real-time events like Mixpannel 5. Support for SQL-like syntax to create complex dashboards(Add On and not necessary)
