Leptos is a full‑stack Rust framework for building web apps that supports client-only SPAs, SSR/MPR rendered on the server, and hydrated progressive apps. It offers fine‑grained reactivity, server functions, and cohesive front‑end/backend code using shared Rust abstractions.
An RPC framework for Rust with a focus on ease of use
...The programming model feels native—call methods on a client stub and await results—while the server side exposes clean concurrency primitives for handling many requests. Because the interface is just Rust code, refactoring and IDE tooling work naturally without an external IDL.
The fast, light, and robust client for the Ethereum mainnet
...OpenEthereum's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing OpenEthereum using the Rust programming language. OpenEthereum is licensed under the GPLv3 and can be used for all your Ethereum needs. By default, OpenEthereum runs a JSON-RPC HTTP server on port :8545 and a Web-Sockets server on port :8546. This is fully configurable and supports a number of APIs. You can generate documentation for OpenEthereum Rust packages that automatically opens in your web browser.
