Description
I've been building Fusor. It's a reactive web framework for Rust where the templates are plain HTML files, so there's no markup living inside Rust macros like view! or rsx!.The state and logic live in ordinary Rust structs, and the whole app compiles to WASM. It also benefits from Rust type checkers, even for the HTML bindings.The Fusor website is fully built using the framework. It's all experimental, so I expect breaking changes and lots of refactors.Any feedback is welcome, and so are contributions! The project is pro AI, if you do decide to contribute.

Could you build this?
No Fusor is a reactive web framework compiling Rust to WebAssembly with custom template compilation, signal reactivity, and fine-grained DOM tracking. Building reactive compilers and WASM framework internals requires deep systems programming, AST manipulation, and framework architecture expertise.
What it would actually take: To build a reactive Rust web framework like Fusor, you need Rust, proc macros / compiler toolchains, and `wasm-bindgen`/`web-sys`. The core difficulty is parsing HTML templates at compile time, connecting expressions to Rust type systems, and generating fine-grained reactive runtime code (signals and DOM mutations) without virtual DOM overhead. This requires specialized compilers and reactive runtime systems engineering experience.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
