Ok so this looks like something I would use for an app we're deploying on-prem. I'm thinking it would make new deployments/releases a bit easier if we could "advertise" upcoming features/versions and allow users to leave feedback, express their interest, or at minimum just let them know what's coming.

My questions are, can I use this without embedding your js, does it support vanilla js frontends, and how easy it is for marketing folks to build and maintain your newspage (eg starting from release notes in markdown).

I think answering these kind of questions in an FAQ on your landing page would help. I could get the gist of your offering by scrolling but no real "aha!" moment. Too much text for not enough info. (For me at least).

Also, really glad your site works without js enabled, bonus points from me!:)
