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.
Personally, I've been using Standard Notes, which desperately wants my money as well (but will not be receiving it, even for advanced features), as well as Joplin (far less aggressively compared to the latter), and Obsidian (a bit more of a hassle)
