Synology Docker aka Container Manager has support for Docker Compose under "Projects". It even explicitly gives you the option or either uploading a ready-made docker-compose.yml or to create a new one.

Personally, I mainly use the CLI to manage my Compose files even on Synology DSM.

I’m surprised that I haven’t noticed this before. When I click on it it still isn’t obvious that this is what it does. It’s more than slightly embarrassing.

Thank you.
