Top 5 Rust websocket-server Projects

websocat

10 6,491 6.6 Rust

Command-line client for WebSockets, like netcat (or curl) for ws:// with advanced socat-like functions

Project mention: Show HN: ScaleSocket – Turn any script into a multiplayer WebSocket server | news.ycombinator.com | 2023-09-20

It's similar to running netcat in server mode, wrapping a script. It's even closer to doing that using websocat [1], whereby one does not have to do the websocket header juggling.
The main difference is that while netcat or websocat will spawn a new process for each connecting client, ScaleSocket has a concept of rooms (channels). For a room, a process is spawned once only. All clients connecting to the same room are routed to the same process. This is not straight forward to do using the forementioned tools.
There's a small comparison page [2] where I have mentioned some alternative tools.

Working on workflow-rs https://github.com/workflow-rs/workflow-rs - an abstraction layer (set of crates) designed to allow creation of async Rust APIs and apps that function uniformly in native and in wasm32 targets. This also includes an async websocket crate (workflow-websocket) that functions uniformly in both targets.
