We were probably writing the first few lines of code for Papercups around the time this article was written (in July), but we're another Intercom alternative :)
Like Chatwoot, we're open source and have a free tier on our hosted version for anyone who'd like to give us a try!
I love your product but might I just say I would be hesitant to use your product for the simple fact that there is no apparent about page on your site. I think it helps to know who is behind a company and there is a clear way, aside from the chat widget, to get contact information.
My company has been using Papercups since it launched. It works pleasingly well for such a new product, and we've found the team very responsive when we've asked for support.
Since you are offering a opensource self hosted alternative along with your paid version, how committed are you folks to not doing a reddit and flipping on the users one day?
