I've tried several launchers in the past decades, across operating systems. On Windows I'm a happy Keypirinha user — it's fast, uses a twentieth of the memory needed by its C# relatives (Run, Flow, etc.), and results appear with almost no latency as I type.

Plenty of plug-ins (list here https://ue.spdns.de/packagecontrol/ ) and they are fairly easy to develop: a Python code that returns a catalog of results, statically or dynamically.
