About Tabby
Tabby is a self-hosted, open-source alternative to GitHub Copilot, built on open-weights code models.
Its whole point is control: completion runs on your own infrastructure, the code is open source, and you choose the open-weights model behind it, with VS Code and JetBrains plugins.
It's for teams who want completion without sending code to a vendor. The trade-offs: self-hosting takes technical setup and adequate hardware (often a GPU), and output quality depends on which open-weights model you deploy behind it.
It's the self-hosted, open option where Copilot and Tabnine are managed services.
