Tabby is built around a hard constraint: enterprises and security-conscious teams cannot send proprietary source code to OpenAI or Anthropic, which rules out the most popular AI coding tools. Tabby solves this by packaging a full inference stack — model server, retrieval-augmented context engine, IDE plugins, and an admin UI — that runs on the team's own GPUs or even on a beefy developer workstation. The result is a self-hosted alternative to GitHub Copilot, with the same core features and no da
