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.
One possible option is to use https://ultibo.org/ - it's based around Free Pascal but the result runs on almost 'bare metal' so it's fast starting and quick to run. You would need to agree with the GNU LGPL version 2.1 licence but there is an exception for closed source development. Though you can draw graphics by direct access to the video buffer it's really designed for character output as there are no tools for buttons / windows etc.
