What is CC GUI? CC GUI (Claude Code GUI) is a free open-source (MIT licensed) JetBrains IDE plugin that brings Claude Code and OpenAI Codex into IntelliJ IDEA through a visual interface, enabling developers to interact with AI using natural language — writing code, refactoring, reviewing — without leaving their IDE. The plugin supports free connection to any third-party LLM API, compatible with Anthropic, OpenAI formats and cc-switch routing, allowing接入 arbitrary OpenAI-compatible providers (SiliconFlow, DeepSeek, etc.). As of May 2026, the plugin has surpassed 20,000 downloads on JetBrains Marketplace and 3,300+ Stars on GitHub.
Claude Code is powerful — but it’s in the terminal. Every time you need to switch windows, type commands, the flow breaks. For Java developers who live in IDEA, this friction adds up fast.
CC GUI solves this by bringing Claude Code and OpenAI Codex directly into your IDEA with a visual interface. You can interact with AI right inside the IDE, write code, refactor, do code reviews — all without leaving your familiar environment. In short: Vibe Coding without the terminal.
CC GUI vs. Leading AI Coding Tools: A Direct Comparison

CC GUI Core Features
Dual AI Engines, One Plugin
CC GUI supports both Claude Code (Anthropic’s official AI) and OpenAI Codex. Switch between them freely without installing separate tools. Perfect for comparing model outputs or using different engines for different scenarios.
Free Third-Party LLM API Support — No Vendor Lock-in
This is one of CC GUI’s standout advantages over other AI coding tools. The plugin ships with a built-in Provider Management system, compatible with cc-switch routing protocol, allowing you to freely connect any OpenAI-compatible third-party API, including:
- SiliconFlow, VolcEngine, Alibaba Cloud and other domestic model providers
- DeepSeek, Kimi, GLM-5 and other popular open-source models
- Locally deployed LLMs (e.g., Ollama)
- Anthropic native API and OpenAI official API
Manage multiple API keys in one place, switch providers per project or scenario — no more fiddling with config files. Supports direct reuse of local settings.json. Developers in China can configure domestic models like GLM-5 and Kimi without being locked into a single API provider.
Visual Interface, No Command Line Required
Claude Code is terminal-native. CC GUI turns it into a GUI — all conversation history, file context, and agent execution status are right there in the sidebar. No command syntax to memorize. Just click and go.
Context-Aware, Precise Code Understanding
The plugin supports @file references — you can directly annotate which files or code snippets the AI should focus on. The AI reads and understands the context automatically, producing more accurate results with fewer “it didn’t get my request” moments.
Skills Slash Commands for Systematic Extensions
Built-in slash commands like /init (initialize project), /review (code review), /refactor (refactor) provide standardized execution flows. AI behavior becomes predictable — no more writing lengthy prompts every time.
MCP Server Support — Extend Beyond the IDE
MCP (Model Context Protocol) is an open standard launched by Anthropic in November 2024 to standardize connections between AI models and external tools. CC GUI fully implements MCP — connect Chrome DevTools (AI-controlled browser for frontend testing), Git Commit MCP (auto-generate commit messages), and more, extending AI capabilities beyond the IDE boundary.
Code DIFF Comparison — Every Change at a Glance
When AI generates or modifies code, CC GUI shows a clear DIFF view: what changed, what was added, what was deleted. Review line by line before accepting — no accidental overwrites.
Permission Management & Security Controls
Following Claude Code’s security architecture, CC GUI provides robust permission controls. AI operations and directory access have clear boundaries — important for team environments.
Multilingual & Theme适配
Auto-switches between Chinese and English, supports dark/light themes, syncs font sizes with IDEA. Visually it feels native — no jarring foreign UI.
Installation & Configuration
Prerequisites
- IDEA version: 2024.2 or higher (upgrade first if below)
- Claude Code SDK: Required for agent execution; the plugin guides you through setup
Installation Steps
Step 1: Install the Plugin
Open IntelliJ IDEA, press Cmd+Shift+A (macOS) or Ctrl+Shift+A (Windows/Linux) to open the Action search, type Plugins and hit Enter. Search for CC GUI and install the most-downloaded one (currently 20k+ downloads).
💡 Tip: There may be two plugins with identical icons. Pick the one with more downloads. No IDE restart required — just find the CC GUI icon in the right toolbar to open the panel.
Step 2: Install Claude Code SDK
On first open, the plugin prompts you to install Claude Code SDK. Follow the guided link — takes about 20 seconds.
Step 3: Configure Model Provider
Click Provider Settings. If you’ve already configured Claude Code locally (typically ~/.config/claude/settings.json), just paste the path. For first-time setup, you can:
- Choose Anthropic official API for Claude models
- Choose OpenAI-compatible format for any third-party LLM API (SiliconFlow, DeepSeek, etc.)
- Use cc-switch routing mode for unified multi-provider management
💡 Tip: CC GUI supports cc-switch routing — connect domestic models like GLM-5 and Kimi without being locked into a single API provider.
Step 4: Monitor Usage
The statistics panel shows token usage per request and cumulative totals. Track consumption and control costs easily.
CC GUI Limitations to Note: CC GUI depends on the Claude Code SDK, which may require additional configuration in network-restricted or enterprise intranet environments. Since Agent auto-execution involves file system operations, be mindful of permission controls and validate in non-production environments before production use.

Conclusion
Key Takeaways: CC GUI moves Claude Code from the terminal into IDEA, lowering the barrier with a visual interface while supporting dual engines, free third-party API connectivity, and MCP for expanded capabilities — particularly suited for developers deeply invested in the JetBrains ecosystem. Pair it with Chrome DevTools MCP to cover frontend debugging scenarios.
CC GUI doesn’t solve the question of “can AI help me write code” — it solves “how can AI help me write code more efficiently in an environment I’m already comfortable in.”
Claude Code is powerful on its own. But moving it outside the terminal and deeply integrating it into the IDE is what truly unlocks its value. CC GUI builds that bridge — Claude Code’s capabilities flow seamlessly into your workflow, becoming part of IDEA.
Tools are extensions of the hand, not replacements for it. Finding the workflow that works best for you is what matters.
CC GUI currently has 3,300+ Stars on GitHub, active community, frequent updates, and responsive bug fixes. The latest v0.4.1 adds MossX support (IDEA 2024.2+). If you develop in IDEA, give it a try — experience AI coding without switching to the terminal.
