ECA (Editor Code Assistant) is a free, open-source, editor-agnostic tool that connects LLMs to editors for AI pair programming, using a well-defined protocol inspired by LSP. Editors spawn the server via `eca server` and communicate over stdin/stdout, so integrations share a single configuration and consistent UX. It suits developers who want chat, rewrite, and completion features across editors like Emacs, VS Code, Vim, IntelliJ, or a desktop app.
