License: Apache-2.0 — Core is Apache-2.0; some enterprise extras (SAML, SSO controls) are gated.
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.

Replaces these SaaS
- GitHub Copilot · AI code completion / chat in the IDE
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.
