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.
As others mentioned, rust_hdl and ghdl ls are worth checking out. If your project has both VHDL and Verilog/SystemVerilog, might be worth checking https://github.com/suoto/hdl_checker (disclaimer, I'm the author). It's got less LS features than the other two but if you use it with modelsim it'll provide mixed language syntax check.
