CodeCompanion.nvim is a Neovim plugin that brings LLM-powered coding into the editor with a chat buffer, inline code transformations, and agentic workflows/tools. It is built around a bring-your-own-LLM adapter system: users supply their own API keys (via environment variables or shell commands) and can target any OpenAI-compatible endpoint through a dedicated openai_compatible adapter with a configurable base URL, or write fully custom adapters. Ships with out-of-the-box adapters for Anthropic, OpenAI, Azure OpenAI, Google Gemini, DeepSeek, Mistral, OpenRouter, xAI, Hugging Face, GitHub Copilot, GitHub Models, Novita, and Ollama/local models.

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
