Hey, had been working on these last few months. It's a way to build web apps with Rust's type safety without depending on complex build systems (only cargo). It's less than 800 lines of code total, has no dependencies but supports routing, reactivity and async that I needed to build meaningful web apps with it
I build one of these visual frameworks too (https://www.ondiagram.com/) and I agree completely with the author.
People think it's a good idea because it will save them time and I get many messages about different questions, use cases and support but the reality is you trade convenience for risk that something will be missing. What most people really want is a boilerplate for the SaaS, some building blocks for their UI and to not think about deployments.
VCs love this too, and many reach out, especially a couple of years ago. Maybe they know something I don't, maybe it was just phase.
