Discord isn’t exactly known for generous file-sharing limits, still, the messaging app offered a 25MB limit to free users. The company has now updated its support page to reflect the upload limit for free users has been lowered to 10MB.
Personally I originally went to Discord because it was the alternative to skype which was increasingly becoming shittier and shittier when Microsoft bought it.
I have a hobby development project with a modest community and maintain a Discord server basically because it’s necessary in order to avoid reducing my potential community reach by at least 50%.
I’m active on GitHub and respond to comments and issues there. I maintain an official thread for my project on the official forum for the game it’s related to. I also keep all documentation, downloads, and guides off Discord and on the clearnet. Discord is still easily 80% or more of where people look for information about the project.
