Twinny is a self-hosted AI coding assistant designed specifically for VS Code.

## What is Twinny?

Twinny is a self-hosted AI coding assistant designed specifically for VS Code.It enables developers to run their own models on local laptops, desktops, or a team gateway, supporting Ollama, llama.cpp, LM Studio, or any OpenAI-compatible server.Its core philosophy is that "nothing leaves your machine unless you point it somewhere," ensuring code privacy and security.

The tool offers features such as code autocomplete, chat, inline editing, code review, and agent mode.All requests are sent only to the server you configure, with no telemetry collection and no account required.Twinny is open source under the MIT license, making it suitable for individual developers seeking maximum privacy as well as teams needing centralized model access management via a unified gateway.

## Key features

- **Local Autocomple**：Provides fill-in-the-middle ghost text completion as you type, working well even on smaller models.
- **Contextual Chat**：Attach files, symbols, the problems panel, git diffs, terminal output, or the workspace index using @ mentions.
- **Inline Edit**：Trigger with Ctrl+I to describe changes, accepting or rejecting each hunk individually; nothing is kept until confirmed.
- **Smart Code Revie**：Review the working tree, a branch against its base, or GitHub pull requests to assist in identifying potential issues.
- **Agent Mode**：Reads, searches, edits files, and runs commands with each step visible; commands ask for permission first, and file changes can be undone.
- **Terminal Integra**：Generates terminal commands from descriptions, showing them before execution, with failures traced to specific files and lines.
- **Workspace Index**：Maintains a keyword and vector index of the workspace, reranked and updated on save to improve code retrieval relevance.
- **Zero Telemetry &**：No accounts, no telemetry data upload, source code is open under the MIT license, and the gateway never calls home.

## How to use it

1. Install the Twinny extension from the VS Code marketplace or via VSX.
2. Set up a model backend on your local machine, such as installing Ollama, llama.cpp, or LM Studio.
3. Configure the model server address in Twinny settings, ensuring requests point to your local instance or designated gateway.
4. Start coding to experience autocomplete; use Ctrl+I for inline edits, or reference context in chat using @ mentions.
5. (Optional) For teams, deploy the twinny-server gateway to centrally manage keys and usage.

## Where it fits

- **Privacy-Sensitiv**：Ideal for regulated industries like finance or healthcare, ensuring proprietary code and data remain entirely on internal networks or local devices.
- **Offline Coding E**：Provides continuous code assistance and completion in environments without stable internet connectivity by relying on locally running models.
- **Team Collaborati**：Offers model access to the entire development team through a single gateway, centralizing API key management, policies, and usage statistics.

## Pricing and free quota

Free for up to 5 developers forever; Personal one-time fee of $29; Team plan at $15 per seat/month (billed yearly) for seats beyond the free 5; Enterprise at $25 per seat/month from 50 seats.
