leptos VS actix-web

Leptos is a modern full-stack framework for Rust, built for fine-grained reactivity, server-side rendering (SSR), and seamless frontend/backend integration. It's similar in spirit to React with Next.js but offers Rust's safety and performance. Leptos integrates with Axum and provides a full-stack development experience — you can write your UI and backend in the same language and reuse logic between the two. It also supports hydration, island architecture, and async rendering. To get started with Leptos, install the CLI and scaffold a project:

How would you compare the two (Dioxus and Leptos)?

The link to Leptos is https://github.com/leptos-rs/leptos for those who need it.

Leptos

Rust? It's built clean from the ground up. The crates.io registry is full of modern, safe, composable libraries. You've got Axum, Rocket and Actix for backends, Leptos, Dioxus, and Yew for frontend, and more. Every library you use follows the same philosophy: safety, performance, and zero tolerance for ambiguity.

> To my knowledge there is not a Vue/React-WASM-type framework out there yet or any framework for building web apps in WASM (without starting from a blank canvas).

Not sure if these qualify, but these Rust web frameworks use wasm:

https://leptos.dev/

https://yew.rs/

Or if you want more Next.JS like, but still fullstack framework there is https://leptos.dev/ and https://dioxuslabs.com/. Maybe dioxus being much more ambitious in its scope (not just web).

1: Actually, that's not true! I use Leptos in their "islands" mode for server side rendering. The entire page is sent as an HTML response, and there is little/no "hydration". The WASM file ONLY includes interactive "islands" that are explicitly marked with the #[island] attribute [0]. In other words, the server binary is handling most of the rendering, similar to if I used a templating tool like Askama or Tera.

2: Leptos is generally slower than vanilla JS, I believe for that reason, but comparable to major JS frameworks [1, 2].

Still doesn't look like it, this is the kind of interactivity I expect.

Where editing the code, immediately shows the GUI related changes on the neighbouring frame.

While what I see on https://leptos.dev/ is just screenshots, and there is nothing on that documentation you linked that provides the same interactive experience, one has to explicitly start a sandbox to host the whole machinery.

Actix Web is a production-grade, high-performance Rust web framework built on the actor model. It’s one of the most mature frameworks in the ecosystem and is known for its blazing speed, extensibility, and feature richness — though it may present a steeper learning curve compared to Axum or Rocket.

To find answers, we wanted to get our hands dirty with three popular Rust web frameworks including rocket, axum, and actix, and get a feeling for their performance, features, and most importantly the developer experience.

So, what framework do I use? Zentrox uses the actix_web framework which is a great library. My DevExp. with this tool was nice. It has good documentation and powerful tools. It was easy to implement for me as I was previously using Express.JS and Flask (Python). Actix also has other helper libraries for files, cookies, sessions,... which I use in my project as well.

Not to compare but i realice this is something you can do with rust with few lines

APIs are often the key to enabling interoperability between AML/KYC solutions and other systems. Design APIs following RESTful principles—using libraries like ExpressJs (JavaScript), Flask (Python), or Actix Web (Rust)—ensuring they are stateless and support the JSON/XML formats expected by most systems. Use Swagger to generate detailed documentation for RESTful APIs to facilitate integration and ensure your APIs are easily consumable by other systems. If you’re building GraphQL APIs, using tools like Apollo Server, Prisma, or Graphene will allow for self-documenting APIs (through GraphQL introspection).
