What is Tabby?

Tabby is an open-source, self-hosted AI coding assistant from TabbyML: you run it on your own servers or GPU machine and connect it to VS Code, JetBrains, or Vim for code completion and chat that never leaves your infrastructure. That makes it a go-to option for companies whose policies forbid sending source code to outside AI services.

Tabby can index your repositories so answers and completions reflect your own codebase, and it supports a range of open code models. The software is free, though you supply the hardware and administration, and a commercial edition adds team management and support; suggestion quality depends heavily on the model you deploy and the GPU behind it.
