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.
Have it open source, OS independent, shareable over LAN/WAN. No subscription, no internet connection required. So yes, every part of it is available on GitHub. Binaries for the win/nix/mac are available, but as I said, a demo system is avaiable as website.
NOTE:
The number of mentions on this list indicates mentions on common posts plus user suggested alternatives.
Hence, a higher number means a more popular project.
