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.
It isn't "linked" to your bank account, but every provider I've used has allowed QIF, OFX or CSV downloads which you can import into it.
Special shoutout to https://www.gnucash.org/ as another FOSS alternative.
