Switching from GitHub Copilot to Tabby

Run `docker run --gpus all -p 8080:8080 -v $HOME/.tabby:/data tabbyml/tabby serve --model StarCoder-1B --device cuda`. Install the Tabby IDE extension (VS Code / JetBrains / Vim / Emacs) and point it at `http://your-host:8080`. Tabby is purpose-built as a Copilot-replacement server — it has a multi-user admin UI, repo-aware indexing, and per-team usage analytics that Continue doesn't try to match.

Good fit for: Teams that want one centrally-hosted code-AI server with admin controls and per-developer usage tracking.
Weak at: Chat / agentic edits — Tabby's strength is completion; for chat-heavy workflows pair with Continue or Aider.
License note: Core is Apache-2.0; some enterprise extras (SAML, SSO controls) are gated.
