A good way to promote that it's open source is to describe it as being self hostable and have a get starting page that quickly says how to self host it.

As for user experience, Vercel has a lot of UX talent but it hasn't been a great user experience for me. I had a glitch on their end that prevented the dashboard from loading for me and it took over a week to resolve, and transferring a domain out turned out to be a manual process. Meanwhile I have had great user experiences with spartan open source projects.
