I have an old phone with microg, slack, tasker and termux running on it. When slack receives a push notification, tasker pulls it out and sends it to a script in termux that forwards it to my gotify server, which my main phone is listening for notifications on.
I’ve emailed Slack a bunch of times asking for unified push or even just an API route I can listen on, but so far I’ve had no luck.
A bit too late to vote (pixelfed.ca would have been mine anyway), but I love how something like this can happen on the fediverse. Other types of services (eg: x.com) are all about competition and screwing over the other guy, and then here you have one instance handing over a perfect domain to another so they can have a better presence.
Huge props to Dan for giving up his domain, as well as to the lemmy.ca team for expanding the fediverse.
