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.
You can install a GUI for it, like (this one)[https://github.com/kunicmarko20/express-vpn-gui/]. It will also create the desktop application for you.
Discord is available as a snap or flatpak. Assuming Nvidia for gpu (you don't say) see https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia.
