Thank you for your feedback!
The Discord server serves as a platform for feedback and discussions about hardware hacking and HardBreak. Do you have any suggestions for alternative ways to offer these features?
Ultimately it's your decision, and I guess Discord is probably easier to manage. Just consider that with Discord the discussions and knowledge that build up on the server don't really belong to you.
In your specific case, you may have to self-host or pay because I don't believe your project would qualify under their open source hosting offering but it wouldn't hurt to ask
