Does anyone have a no-nonsense way of cross posting between Mastodon and Bluesky?

I’m hoping for a solution that is relatively simple to set up and manage, but also possibly supports multiple users for cross posting needs.

Ideally, I wouldn’t have to do this, but in a world where I might have to manage both, it would be really awesome to have this set up on my own computer with simple API access to both platforms.

I should note that I looked into n8n which seems like it might be OK for this use case, but I’m highly skeptical of all the AI stuff mentioned in the various Youtube videos. Is it possible to completely ignore the AI stuff or is it entirely engrained in the system? Also, are there presets that are friendly for lemmy, mastodon and bluesky?
