About:
lspmux is a multiplexer that allows multiple Language Server Protocol (LSP) clients to share a single language server instance. This reduces resource consumption by avoiding the overhead of running separate language server processes for each editor or IDE session. It is particularly useful for developers working with resource-intensive language servers.

Key Features:

Shares a single LSP server instance across multiple clients
Reduces CPU and memory usage
Transparent to LSP clients
Supports standard LSP over stdio

Use Cases:

Running multiple editor instances (e.g., VS Code, Neovim) that connect to the same language server
Developing in resource-constrained environments where running multiple language servers is prohibitive
Centralizing language server management for a development environment

Alternatives:

lsp-proxy – Similar concept but may have different implementation details and feature sets.
