InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Prior to 2017, Ghostery belonged to a company named Evidon (which had a business model of collecting and selling data to other companies). It was then acquired by Cliqz (which builds a private and independent search engine as well as privacy-focused browsers). Since then the business model has been dropped, code has been open-sourced and Ghostery is now exploring ways to monetize through paid products. (source)
Ghostery neither collects nor sells data about users or trackers. In fact, they even open the insights they have about the tracking landscape via https://whotracks.me/ so that everyone can benefit from it.
