Cline + Volcengine Ark Coding Plan Setup Guide

This guide walks you through setting up the Cline + Volcengine Ark Coding Plan — currently the most cost-effective AI coding solution for developers in China, with Lite starting at ¥40/month (¥9.9 first month promo), no VPN required, and access to multiple top-tier coding models.

Prerequisites

• VS Code (or a compatible editor such as Cursor or Windsurf)
• A Volcengine account (a ByteDance platform — you can register with a phone number)
• About 10 minutes of setup time

---

Step 1: Subscribe to the Volcengine Ark Coding Plan

1. Visit the Volcengine Ark Coding Plan page
2. Choose a plan:
   • Lite: 9.9 CNY/month (first-purchase discount, regular price 40 CNY) — suitable for personal daily use
   • Pro: 49.9 CNY/month (first-purchase discount, regular price 200 CNY) — suitable for heavy users
3. Complete the subscription using Alipay or WeChat Pay

Tip: The first-month discount is substantial. If you’re unsure whether it’s right for you, start with the Lite plan for a one-month trial.

Step 2: Obtain Your API Key

1. Log in to the Volcengine Console
2. Navigate to “API Key Management” or search for “Ark”
3. Create a new API Key, then copy and save it securely

---

Step 3: Install the Cline Extension

1. Open VS Code
2. Press Ctrl+Shift+X (Mac: Cmd+Shift+X) to open the Extensions Marketplace
3. Search for Cline and click Install
4. Once installed, the Cline icon will appear in the left sidebar

---

Step 4: Configure Cline to Connect to Volcengine Ark

1. Click the Cline icon in the left sidebar to open the Cline panel
2. Click the gear icon in the top-right corner to enter Settings
3. In the API Provider dropdown, select OpenAI Compatible
4. Fill in the following configuration:

API Key:      The key you obtained in Step 2
Base URL:     https://ark.cn-beijing.volces.com/api/coding/v3
Model:        ark-code-latest

Note: The Coding Plan uses a dedicated endpoint /api/coding/v3 (different from the standard Ark API endpoint /api/v3). ark-code-latest is the recommended model ID for the Coding Plan — Ark will automatically route to the optimal coding model without requiring you to manually create an endpoint. If you prefer a specific model, you can also enter doubao-seed-code-preview-latest.

---

Step 5: Test the Configuration

1. Type in the Cline chat box: Hello, please introduce yourself
2. If you receive a normal response, the configuration is successful
3. Try asking Cline to write some code: Write me a Python bubble sort function

Step 6: Start Using Cline

Basic Usage

Open any project file and describe what you want to do in Cline:

Refactor src/utils/auth.ts — extract common functions and add error handling

Cline will automatically:

1. Read the relevant files
2. Analyze the code structure
3. Propose a modification plan
4. Wait for your confirmation before applying the changes

Recommended Workflows

• New feature development: Create a new UserProfile component under src/components/, following the style of src/components/Card.tsx
• Bug fixing: Line 45 of src/api/user.ts is throwing an error — analyze and fix it
• Code review: Review the code in the src/services/ directory and identify potential issues

FAQ

Q: What are the request limits?

The Lite plan allows approximately 1,200 requests per 5-hour window; the Pro plan allows approximately 6,000. This is sufficient for daily coding. For intensive Agent tasks, the Pro plan is recommended.

Q: Which models are supported?

The Coding Plan includes:

• Doubao-Seed-Code: ByteDance’s in-house coding model
• DeepSeek-V3.2: Strong general-purpose capabilities
• GLM-4.7: From Zhipu AI
• Kimi-K2.5: From Moonshot AI
• Kimi-k2-thinking: Moonshot AI’s reasoning variant
• Auto mode (ark-code-latest): Automatically selects the optimal model

Q: How does this compare to using the Claude API directly?

Comparison	Cline + Ark	Cline + Claude API
Monthly cost	40–200 CNY (first month 9.9–49.9 promo)	$30–100+
China access	No VPN required	VPN required
Model quality	8/10	9.5/10
Cost-effectiveness	★★★★★	★★★☆☆

Q: Can Roo Code use this same configuration?

Yes! Roo Code’s configuration process is identical to Cline’s — simply apply the same settings in Roo Code’s settings panel.

Advanced Tips

Custom System Prompts

In Cline’s settings, you can add a CLAUDE.md file (or .clinerules) to help Cline better understand your project:

# Project Guidelines
- Use TypeScript in strict mode
- Write function comments in Chinese
- Use the Result<T, E> pattern for error handling

Extend Capabilities with MCP

Cline supports MCP (Model Context Protocol), allowing you to connect to external tools such as databases, Figma, browsers, and more:

1. Go to the MCP configuration section in Cline’s settings
2. Add the MCP Server you need
3. You can now use the additional tools in your conversations
