The best alternatives to Pairagraph are Talkshow, Flarum, and ChannelSync. If these 3 options don't work for you, we've listed a few more alternatives below.
Hi Hunters! Today I'm launching Talkshow. It's sort of like a reddit forum for your team, but with mini video clips (max 1 minute) so you can see / hear your team mates more frequently :)
Simple, fast and free. We empower people and companies to connect intellectually and emotionally through online communities, by providing a technically excellent, open and extensible discussion platform.
Discord is great, we know it, but unfortunately it acts as a gateway for information openess. Great content is kept hidden from search engines and potential interested people. With ChannelSync you can create a public forum with your best conent of your server.
