Amiga is a broad term: what chipset etc.?
What I really highly advise is this MS Studio Code Plugin:
https://github.com/BartmanAbyss/vscode-amiga-debug
For me a revelation in ease of use. Hit compile and run - and it does in an emulator.
You can use C or Assembler.
The author is a well-known scene contributor since the 80th, and does a hell of a job with this nice IDE.
Best tool and workflow for someone like me, who only casually writes some not so leetcode Amiga 500 ECS demos these days.
