avante.nvim is an open-source Neovim plugin that emulates the Cursor AI IDE inside the editor, providing agentic AI-assisted code suggestions that you can review as diffs and apply directly to your source files. It is fully bring-your-own-key: users supply their own provider API keys via scoped environment variables (e.g. AVANTE_ANTHROPIC_API_KEY, AVANTE_OPENAI_API_KEY) or legacy global vars, or by pointing api_key_name at a shell secret-manager command (cmd: prefix). Each provider's endpoint/base URL is configurable, and the __inherited_from = 'openai' mechanism lets users wire up any OpenAI-compatible vendor. Supported providers include Anthropic, OpenAI, Azure OpenAI, Google Gemini, Cohere, Amazon Bedrock, Ollama/local models, OpenRouter, DeepSeek, Groq, Mistral, Perplexity, and arbitrary custom OpenAI-compatible endpoints. The plugin is free and Apache-2.0 licensed; the user pays their chosen provider directly. Verified June 2026: ~17,981 GitHub stars, Apache-2.0, actively maintained (last push June 20 2026, recent release avante-libs v0.1.2 on June 3 2026).

How your API key is handled

Your API key is supplied via an environment variable or local config file. 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

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
