About:
ra-multiplex is a proxy that manages a single rust-analyzer server instance and shares it across multiple LSP clients. It significantly reduces CPU and memory usage by preventing redundant language server processes. This is particularly useful when working on the same project from multiple editors or terminals.

Key Features:

Resource-efficient single server instance
Supports multiple concurrent clients
Fast client connection and initialization
Standalone proxy architecture

Use Cases:

Running rust-analyzer in both Neovim and VS Code simultaneously
Reducing memory usage on laptops during heavy development
Using a persistent rust-analyzer session across terminal multiplexers like tmux

Alternatives:

rust-analyzer standalone – ra-multiplex wraps the standard rust-analyzer binary to add sharing capabilities
