Twinny

Overview

An open-source VS Code coding assistant for completion, inline editing, chat, and reviews using local or hosted models. It is most useful when the task matches its specific workflow, and generated code or recommendations should be tested before production use.

What is Twinny?

Twinny is a VS Code coding assistant that keeps model communication under the developer's chosen infrastructure. It supports code completion, inline edits, chat, and code review while allowing local models, remote model servers, or hosted APIs to be selected.

It is a practical option for developers who want a familiar VS Code workflow without sending all coding context to a single proprietary service. The trade-off is that users must understand model endpoints and choose models capable of code completion or instruction following. Performance therefore varies with the selected model and hardware.
