Yes, I use my Conduit instance for all my development work and also host a big Discord bridge on it (for https://veloren.net, which was mentioned in another comment).
Sounds like AppService/bridge support is on par with Synapse at this point (and maybe has been for quite a while?) - any gaps to be aware of in that department?
You can find some bridge documentation here: https://gitlab.com/famedly/conduit/-/blob/next/APPSERVICES.m...
