Zeppelin
"A web-based notebook that enables interactive data analytics. You can make beautiful data-driven, interactive and collaborative documents with SQL, Scala and more."
PipelineDB—The Streaming SQL Database
"An open-source relational database that runs SQL queries continuously on streams, incrementally storing results in tables."
Segment - We make customer data simple.
"Segment isn't an analytics tool. We're the infrastructure that organizes behavioral data from your product and sends it wherever you want."
SlamData
"SlamData lets analysts easily run SQL queries and build reports directly on data stored in MongoDB, no data relocation required."
Riveted - A Google Analytics plugin for measuring active time on site
"Google Analytics does a lot of things really well but the way it measures visit duration—by calculating the time difference between subsequent pageviews—provides only a partial view of how much time is actually spent on site.
Riveted helps fix this by measuring the amount of time users are actively engaged (e.g., clicking, scrolling, using the keyboard) and then reporting the data to Google Analytics in frequent intervals.
It supports Universal Analytics, Classic Google Analytics, and Google Tag Manager. It can also be used with any analytics tool that supports events, e.g. Mixpanel or Keen.io."
Scroll Depth - A Google Analytics plugin for measuring page scrolling
"Scroll Depth is a small Google Analytics plugin that allows you to measure how far down the page your users are scrolling. It monitors the 25%, 50%, 75%, and 100% scroll points, sending a Google Analytics Event at each one.
You can also track when specific elements on the page are scrolled into view. On a blog, for example, you could send a Scroll Depth event whenever the user reaches the end of a post."
Screentime - Measure how much time things spend on-screen
"Screentime is a small tool that helps you start thinking of your website traffic in terms of time instead of hits (pageviews, visits, etc). You can define areas of the page, called Fields, and then Screentime will keep track of how much time each Field is on screen for. You can also use it to track smaller elements, like ad units. Screentime only handles the client side work. You'll need to provide your own backend to post the data to. I've included an example that shows how to this with Keen IO using only a few lines of code. There's also a built-in option for posting to Google Analytics but there are some caveats (see below)."
