About ECA
ECA (Editor Code Assistant) is a free, open-source, editor-agnostic AI coding tool that connects LLMs to code editors through a protocol inspired by LSP. It supports VS Code, Emacs, Neovim, and IntelliJ, and works with multiple model providers including OpenAI, Anthropic, GitHub Copilot, and Ollama.
About Pi
Pi is a minimal, opinionated terminal-based coding agent created by Mario Zechner, the creator of libGDX. It ships with just four core tools—read, write, edit, and bash—and a system prompt under 1,000 tokens, emphasizing simplicity and extensibility. Pi supports TypeScript extensions and skills for customization, and it powered the OpenClaw project that reached over 145,000 GitHub stars.
