Tabby
The self-hosted AI coding assistant with context-aware completions — privacy-first, on-prem and open source. A GitHub Copilot alternative your team fully controls.
GitHub CopilotAbout Tabby
Tabby is a self-hosted AI coding assistant built for teams that can't send their source code to a third-party cloud. You run it on your own hardware — including your own GPU — and it delivers context-aware completions across popular IDEs while your code never leaves your network.
It indexes your repositories to give suggestions grounded in your actual codebase, supports team deployment with admin controls, and works with a range of open models. That makes it a genuine on-prem alternative to GitHub Copilot for privacy-sensitive organisations.
It's Apache-2.0 licensed with an active community and steady releases. For regulated industries or any team that wants Copilot-style help without the data leaving the building, Tabby is the leading open, self-hosted choice.
