Leptos
Rust framework for building reactive web applications, client-side or full-stack with server rendering and server functions.
Leptos is a Rust framework for reactive web applications. A client-side app is built with Trunk, and a full-stack app uses Actix-web or Axum as its server library. The framework includes server functions.
Client-side builds can be hosted on any service that supports static site deploys, as the CSR deployment guide puts it. A full-stack app is deployed to server or container hosting services, as the SSR deployment guide describes. The project is maintained in the leptos-rs organization on GitHub, and the book at book.leptos.dev is its main documentation.
Worth knowing
The stable release line is still below 1.0, and a release candidate newer than the latest stable release is published.
