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.

Why this trust score (83/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 21/25: The key lives in a deployment you run yourself.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under Apache-2.0, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed: commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [CONFIRMED · SOURCE_SCAN] Ships a container definition, so it can be self-hosted on your own infrastructure. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-08-10, about 0 month(s) ago. source

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.
