lspmux for Mac

lspmux is a command-line tool for sharing a single language server instance among multiple LSP clients. When writing code in an editor, each window opened or client connected often requires starting a separate language server, and over time this leads to duplicated memory and CPU usage. lspmux routes requests to one shared instance so multiple clients reuse the same language service, reducing wasted resources. It suits developers who frequently keep several editor windows open and care about machine load, especially those accustomed to configuring their toolchain in the terminal. If you already use LSP for completion, navigation, and diagnostics but don't want to pay the startup and runtime cost repeatedly for every client, you can try using it for unified scheduling.
