About Twinny
Twinny is a Visual Studio Code extension that adds AI code completion, chat, edits and code reviews to the editor. You connect it to the model of your choice, whether it runs locally on your own machine or on a hosted service, so your code does not have to go to a particular vendor.
The repository also contains a Twinny server package and Helm deployment files for teams that want to run the backend on their own infrastructure. It suits developers looking for a Copilot-style assistant they control.
