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.
Cody is Sourcegraph's AI coding assistant that understands your entire codebase. It uses Sourcegraph's code graph to provide context-aware code completions, explanations, and refactoring across massive codebases. Cody supports multiple LLM backends and works in VS Code, JetBrains, and the web.
