One of the things I liked about Parse.com was the ability to easily set up a PFUser and allow for different channels for targeting push notifications using PFCloud. Is there a still a way to do this now that parse is shut down?
The API is still the same, so yeah. There are some missing functionalities like localized PNs, scheduled PNs using the user's timezone, analytics, etc.
You can deploy our own (https://github.com/parse-community/parse-server & https://github.com/parse-community/parse-dashboard) or pay a Parse provider (there are quite a lot now. Here's a list of the ones recommended by the community: https://github.com/parse-community/parse-server/wiki#hosting-services). Some providers offer some functionalities that others don't, you might want to check the roadmap on their sites.
