Process and control your own user event data. Apache Distill is Flagon's experimental, customizable analytics stack built in Python that interfaces directly with Elastic. It gives data scientists and developers the power to segment and model user data in Python or push modeling output to visual analytic applications. From simple aggregations to complex graph models of user workflow, Distill provides access to user data and the python libraries you love in a streamlined analytical pipeline.
Apache TAP is Flagon's experimental collection of specially modified D3 visual analytic libraries for exploring Apache UserALE.js data. You can explore them in our sandbox environment, or embed them in your own applications. With TAP, Gain insight from advanced sequential and graph models and reveal trends in usage across users of different types and experience, and trends across different versions of your application. Try out our Bowie plot demo below!

Stage systematic user research on the web. Apache STOUT provides everyone the ability to perform user research on the web. Track research participants through different tasks with your web applications, or track them through different versions of the same web application. Apache STOUT allows you to manage user research participants and data collected through Apache UserALE and 3rd party form data services.

About the Project

Apache Flagon is a free and open-source, thin-client behavioral logging solution for business analytics, usage analytics, usability testing and scientific research. Formerly named Apache SensSoft, Flagon had its start at Draper for DARPA's XDATA program and represents the hard-work and innovations of an interdisciplinary team of data scientists, psychologists, developers and system architects. Apache Flagon is maintained by the people that love it under the mentorship and guidance of the Apache Incubator. Join the conversation and the community!
