For us Keen is a near perfect fit for our data streaming and aggregation needs. It starts with the availability of SDKs in multiple languages, and the ability to stream unlimited events using these SDKs or the API, allowing us to capture all the user engagement data we could dream of. Furthermore we find the caching abilities of queries and datasets to be an extremely powerful tool to serve up high value data aggregates with exceptionally low latency and high stability. Support has always been incredibly attentive, quick to respond and willing to work together to maximise the benefits achievable by utilising Keen's tools. Documentation of the API and different packages is informative and clear. Review collected by and hosted on G2.com.
We find the front-end UI to be a bit clunky; navigation between projects and different pages within the project could be a fair bit smoother and more intuitive. Review collected by and hosted on G2.com.
