Tabby is a self-hosted AI coding assistant that runs as a server (binary, Docker, or Homebrew) and provides code completion and chat as an open-source, on-premises alternative to GitHub Copilot, with IDE extensions for VS Code, JetBrains/IntelliJ, and Vim/Neovim. It is BYOK: via ~/.tabby/config.toml's HTTP Model Connector you configure completion, chat, and embedding models against external providers using your own api_key and api_endpoint. The docs include dedicated configuration pages for OpenAI, Azure OpenAI, Anthropic Claude, Mistral AI, OpenRouter, DeepSeek, Perplexity, Fireworks, Hugging Face, Amazon Bedrock, plus local engines (Ollama, vLLM, llama.cpp, LM Studio) and arbitrary OpenAI-compatible endpoints. Core is Apache 2.0; an "ee/" enterprise directory carries a separate license. ~33.6k GitHub stars, actively maintained (v0.32.0, Jan 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.
