Keen IO is a platform built for developers to ship custom user-facing metrics. It can collect, store, enrich, and then send data to systems like Amazon S3.

Similar to Mixpanel and Kissmetrics, Keen IO provides a code snippet to put in your application, website, or server, at which point it begins recording event data like clicks and conversions. Keen IO has a cloud database that stores that event data, analytics APIs that can run counts, sums, funnels, and more, and visualization tools that allow you to chart and display your data in dashboards.
