@arinbasu yes exactly and that is what the intent was, to create an ecosystem of free, opensource (and ideally federated) apps that can work together to enable STEM professionals to collaborate on open projects.
gitlab acts as a source repository
funkwhale acts as a way to do podcasts
peertube is a replacement for youtube for posting videos and media
discourse acts as mailing lists for projects (I can setup sub forums for any specialized projects)
Stuff like that. Where possible i tried to use projects based on ActivityPub so they are on the fediverse. For example you can follow a peertube account from your main QOTO account here. That way when someone posts a video on the peertube account it will show as a post here in your home timeline. So everything (where possible) all talks to eachother.
