Overview

CodeCompanion adds a chat buffer, inline code transformations and an action palette to Neovim, backed by HTTP adapters for providers such as Anthropic, OpenAI, Gemini, Copilot and Ollama. It also connects to CLI agents like Claude Code, Codex and Gemini CLI through the Agent Client Protocol, and to MCP servers. It is written in Lua and installs through lazy.nvim or any other plugin manager.

Who it is for: Neovim users who want LLM chat and coding agents in their editor

Strengths

Many built-in adapters, including Ollama, OpenRouter and Azure OpenAI, plus a custom adapter API
ACP support lets Claude Code, Codex, Gemini CLI and others run inside Neovim
Supports MCP, skills, rules files (CLAUDE.md, .cursor/rules) and custom prompts
Review UI to comment on and approve or reject agent code changes

Weaknesses

Works only inside Neovim
Depends on plenary.nvim and nvim-treesitter being installed
Maintainer accepts contributions at his discretion
Hardware requirements for local models are not documented

What it needs

Docker
Needs Neovim, plenary.nvim, nvim-treesitter
Models: Anthropic, OpenAI, Azure OpenAI, Google Gemini, GitHub Copilot

How to choose

Check which models it can use: your own keys, local models, or only the vendor's.
See what it may do without asking (edit files, run shell, push) and how you approve.
Prefer agents that work in a branch or worktree you can throw away.
