Cline Integration

Use QCode.cc API with the Cline extension in VS Code

Cline Integration ¶

Cline is a popular VS Code AI coding extension (5M+ installs) that supports any AI model and custom API endpoints. By pairing Cline with the QCode.cc API, you can use Claude models in VS Code at low cost.

Why Cline?¶

Zero markup: No markup on model costs — you only pay QCode.cc API fees
Flexible model switching: Switch between Claude, GPT, Gemini, and more in the same interface
Deep VS Code integration: Sidebar panel, inline code actions, file edit preview
Fully open source: Transparent code, active community
CLI 2.0: Supports terminal mode and parallel agents

Installation & Configuration ¶

Step 1: Install the Cline Extension ¶

In VS Code:

Open the Extensions panel (Ctrl+Shift+X / Cmd+Shift+X)
Search for "Cline"
Click Install

Step 2: Configure QCode.cc API ¶

After installation, click the Cline icon in the VS Code sidebar
In the API Provider dropdown, select "OpenAI Compatible"
Enter the following information:

Setting	Value

API Key	Your QCode.cc API key (starts with `cr_`)
Model ID	`claude-sonnet-4-6` (recommended) or `claude-opus-4-6`

Step 3: Verify Connection ¶

Type a simple message (e.g., "Hello") in the Cline chat box. If you receive a response, the configuration is successful.
