Hey, I'm one of the founders of Baserow. We launched the beta of our application builder last week. It allows you to build database-driven websites, web applications, and portals. It's in the same product as our database module, and will work seamlessly together with it. More information can be found in the release blog post linked to this post, and in this video
https://www.youtube.com/watch?v=yjE7gxkPlDs. Even though it's in an early state, it's already possible to try it out on
https://baserow.io or by self-hosting the latest version. Happy to answer all the questions you might have.
