Key Points

It seems likely that Cline can be used in VSCode by installing the extension, creating an account, and interacting via natural language prompts.
Research suggests configuring an API provider, like OpenRouter, enhances functionality, requiring an API key.
The evidence leans toward Cline supporting advanced features like code generation and terminal commands, with optional setup for specific models.

Installation and Setup

To get started with Cline in VSCode, first ensure you have VSCode installed from this website. Then, open VSCode, go to the Extensions view (click the Extensions icon or press Ctrl+Shift+X on Windows/Linux, or Cmd+Shift+X on macOS), search for “Cline,” and click “Install.” After installation, click the Cline icon in the Activity Bar or use the command palette (Ctrl+Shift+P or Cmd+Shift+P) to open Cline, then sign in by creating an account on app.cline.bot, which starts with free credits and no credit card needed.

Using Cline

Once set up, interact with Cline by typing natural language prompts in the chat window, such as “Generate a function to sort an array” or “Create a new project folder called ‘hello-world’ with a simple webpage saying ‘Hello World’ in big blue text.” Cline can generate code, explain it, debug errors, and even execute terminal commands with your permission, like installing packages. Review all changes before applying, as AI suggestions may occasionally be incorrect.

Configuring API Provider

For enhanced functionality, you can configure an API provider like OpenRouter. Obtain an API key from OpenRouter.ai, then in Cline’s settings, enter the Base URL (e.g., https://openrouter.ai/api/v1) and Model ID (e.g., deepseek/deepseek-chat), and paste your API key. This allows access to specific models, potentially improving performance, but it’s optional as Cline works with default models out of the box.

Background on Cline and VSCode Integration

Cline is an open-source AI coding assistant designed to enhance developer productivity by offering features like code generation, debugging, and terminal command execution within VSCode. It supports multiple AI models and can be configured with various API providers, making it a flexible alternative to tools like GitHub Copilot. Users can interact with Cline using natural language prompts, and it adapts to project-specific needs through custom instructions and settings.

Step-by-Step Installation and Setup

To begin using Cline in VSCode, follow these detailed steps:

Install VSCode:
- Download and install VSCode from the official website: this website. Ensure you allow extensions to run if prompted upon launch.
Install the Cline Extension:
- Open VSCode and navigate to the Extensions view by clicking the Extensions icon in the Activity Bar or pressing Ctrl+Shift+X (Windows/Linux) or Cmd+Shift+X (macOS).
- In the search bar, type “Cline” to find the extension.
- Click the “Install” button next to the Cline extension, developed by saoudrizwan, available at VSCode Marketplace.
Open Your Cline Folder:
- For a structured setup, open the “Cline” folder in your Documents directory:
  - On macOS: /Users/[your-username]/Documents/Cline
  - On Windows: C:\Users\[your-username]\Documents\Cline
- This step is recommended for organizing projects but optional for basic usage.
Create a Cline Account and Sign In:
- After installation, click the Cline icon in the Activity Bar to open the extension, or use the command palette (Ctrl+Shift+P or Cmd+Shift+P) and type “Cline: Open In New Tab” for a better view.
- Click “Sign In” in the Cline interface, which will redirect you to app.cline.bot to create an account. This process starts with free credits, and no credit card is required, making it accessible for new users.

Configuring API Providers for Enhanced Functionality

Cline supports a wide range of API providers to leverage different AI models, which can be configured for improved performance and access to specific models. The configuration process is optional but recommended for users seeking advanced features. Here’s how to set it up:

Supported API Providers: Cline integrates with providers like OpenRouter, Anthropic, OpenAI, Google Gemini, AWS Bedrock, Azure, and GCP Vertex, as well as any OpenAI-compatible API or local models via LM Studio/Ollama.
Configuration Steps:
- Open the Cline extension in VSCode and access the settings, typically via a gear icon or through VSCode’s settings menu.
- Select your preferred API provider. For example, to use OpenRouter:
  - Obtain an API key from OpenRouter.ai, ensuring to enable spending limits for cost control.
  - Enter the Base URL: https://openrouter.ai/api/v1.
  - Specify the Model ID, such as deepseek/deepseek-chat for DeepSeek Chat.
  - Paste the API key into the designated field and save the settings.
- For local setups, such as using Ollama:
  - Install Ollama from ollama.com.
  - Pull the desired model, e.g., ollama pull deepseek-r1:14b, and configure Cline with the Base URL http://localhost:11434 and the appropriate Model ID.
Performance Considerations: The choice of model affects performance based on hardware. The following table outlines hardware requirements for different model sizes:

Model Size	RAM Needed	Recommended GPU
1.5B	4GB	Integrated
7B	8–10GB	NVIDIA GTX 1660
14B	16GB+	RTX 3060/3080
70B	40GB+	RTX 4090/A100

Cost Considerations: For cloud-based providers like OpenRouter, costs are approximately $0.01 per million input tokens, with detailed pricing at OpenRouter pricing. Local setups with Ollama are free but require sufficient hardware.

Using Cline for Coding Assistance

Once installed and configured, Cline offers a range of features to assist with coding tasks. Here’s how to use it effectively:

Interacting with Cline:
- Open the Cline chat window by clicking the Cline icon in the Activity Bar or using the command palette to open it in a new tab.
- Type natural language prompts to request assistance. Examples include:
  - “Generate a function to sort an array.”
  - “Explain this code snippet.”
  - “Create a new project folder called ‘hello-world’ and make a simple webpage that says ‘Hello World’ in big blue text.”
- For complex tasks, provide context, such as project goals or specific actions, to get more accurate responses.
Advanced Features:
- Code Generation and Editing: Cline can generate code and edit files. Use commands like “Please edit /path/to/file.js” or “@filename” to specify files. It will show changes in a diff view for review before applying, ensuring control over modifications.
- Terminal Command Execution: Cline can execute terminal commands with user permission, such as installing packages or running build scripts. For example, you can ask, “Install the latest version of Node.js,” and Cline will confirm before proceeding.
- Custom Instructions: Set custom instructions in the Cline settings to guide its behavior, such as enforcing coding standards, defining error handling preferences, or establishing documentation practices. These can be project-specific and stored in a .clinerules file in the project root.
Review and Apply Changes: Always review AI-generated code before applying, as it may occasionally be plausible but incorrect. Cline’s checkpoint system allows you to roll back changes if needed, ensuring controlled progress.

Additional Tips and Best Practices

To maximize the utility of Cline, consider the following:

Asking Questions: If unsure, type your query directly into the Cline chat. For example, “How do I fix this error?” Provide additional context, such as screenshots or copied error messages, for better assistance.
Usage Limits and Transparency: Cline tracks total tokens and API usage costs for the entire task loop and individual requests, keeping you informed of spending, especially useful for cloud-based providers.
Community Support: For further assistance, join the Cline Discord community at this link, where you can find troubleshooting guides and connect with other users.
Model Selection: Choose models based on your needs, with options like Anthropic Claude 3.5-Sonnet, DeepSeek Chat, and Google Gemini 2.0 Flash available, each offering different strengths for coding tasks.

Unexpected Detail: Flexibility in Model Deployment

An interesting aspect of Cline is its flexibility in supporting both cloud-based and local model deployments. While most users might expect cloud-based AI assistants to dominate, Cline’s integration with local setups via Ollama allows for cost-free, privacy-focused coding assistance, provided you have sufficient hardware. This dual approach caters to diverse user needs, from budget-conscious developers to those prioritizing data security, and is particularly relevant for open-source enthusiasts.

Conclusion
