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.
LibreOffice is free. Tbh, I do most of my drafts on GoogleDocs. There are a range of premium writing software offerings as well, but most of them aren't really worth it unless you're planning on self-pubbing a fair amount.
