Exploring Google’s Gemini CLI: Top Features and a Coding Showdown with Claude Code

Google has recently launched the Gemini CLI, an AI-powered coding assistant that brings a fresh wave of capabilities to developers. While it might initially feel like a competitor or knockoff to existing tools such as Cloud Code, Gemini CLI shines with several powerful features that can significantly enhance your coding and development workflow. In this post, we’ll explore the top five standout features of Gemini CLI, and then dive into a real-world coding comparison between Gemini CLI and Claude Code to see how they stack up.

1. Generous Free Tier with Powerful AI Models

One of the most exciting aspects of Gemini CLI is its free tier, which is exceptionally generous compared to competitors. With just a standard Google account—no credit card required—you gain access to the Gemini 2.5 Pro model, arguably one of the best AI models available for coding right now.

• Rate Limits: 60 requests per minute and 1,000 requests per day for free.
• Comparison: Claude Code’s base plan costs $20/month and offers significantly less.

This free access to a powerful AI model is a game changer for developers who want to experiment or build without immediate costs.

2. Integrated Google Search for Up-to-Date Information

Google’s expertise in search is seamlessly integrated into Gemini CLI. When the tool encounters a query or coding problem that requires the latest information from the web, it can automatically perform a Google search and incorporate those results into its responses.

• This means Gemini CLI can provide current, accurate coding standards and technology updates without you needing to search separately.
• The integration is smooth—search happens behind the scenes and enriches the AI’s understanding in real-time.

This feature ensures that developers get grounded, relevant answers reflecting the most recent tech developments.

3. Non-Interactive Mode for Flexible Terminal Usage

Gemini CLI isn’t limited to interactive conversations. It also supports a powerful non-interactive mode, allowing you to execute it within scripts or pipelines directly from the terminal.

• Use the -d prompt flag to run commands non-interactively.
• You can pipe files into Gemini CLI and output results directly to files.
• For example: Summarize an entire project into bullet points and generate markdown documentation automatically.

This flexibility makes Gemini CLI a strong candidate for automation, batch processing, and integration into larger development workflows.

4. Massive 1 Million Token Context Window

One of Gemini CLI’s most impressive technical features is its enormous context window—up to 1 million tokens.

• This allows the AI to load entire large projects (such as a full Shopify site) into its memory.
• It understands relationships across multiple files and can make changes with full awareness of dependencies.
• This reduces the risk of breaking unrelated parts of the codebase when making updates.

A large context window is crucial for complex software projects and collaborative coding environments.

5. Multimodal Capabilities: Beyond Text Coding

Gemini CLI supports multimodal inputs and outputs, going beyond just text.

• You can convert documents like invoices into JSON files effortlessly.
• The CLI reportedly integrates with VO MCP servers to generate images and videos from within the tool.
• This opens up possibilities for handling diverse data types—images, sound, video—directly in your development workflow.

For AI software developers, this multimodal ability could streamline many tasks that traditionally require multiple separate tools.

Gemini CLI vs Claude Code: Real-World Coding Challenge

To test Gemini CLI’s coding prowess, a real-world example was used—a Shopify-based map showing retail locations with street view markers. The goal was to add a directions button that opens Google Maps with navigation to the selected store.

Gemini CLI’s Approach

• Successfully found and modified the correct part of the codebase.
• Added a fully functional directions button that opened Google Maps correctly.
• Encountered minor quirks such as non-English characters appearing in the code.
• Sometimes switched from the Pro model to a lower-tier “Flash” model during coding, which can be remedied by restarting the CLI.

Testing More Complex Features: Dynamic Zoom Level Based on Device Resolution

• Gemini CLI implemented a simple zoom-level adjustment based on window width thresholds.
• However, the approach was somewhat naive and resulted in suboptimal map views on desktop and mobile.
• It did not account for factors like device pixel ratio or aim to maximize visible locations intelligently.

Claude Code’s Superior Handling

Using the exact same prompt, Claude Code produced a smarter implementation:

• Calculated an effective width by multiplying screen width by the pixel ratio.
• Used more granular zoom level categories.
• Resulted in better map zoom behavior on different devices.

Summary: Where Gemini CLI Stands Now

• Strengths: Gemini CLI excels in accessibility with its free tier, massive context window, Google search integration, and flexibility via non-interactive mode.
• Multimodal functionality also sets it apart for diverse AI-assisted development tasks.
• Coding ability: It handles simple tasks confidently but falls behind Claude Code on more complex programming challenges.
• Model switching quirks and occasional hallucinations (e.g., strange characters) indicate room for refinement.

For developers looking to try out cutting-edge AI coding tools for free and those who value integration with Google’s ecosystem, Gemini CLI offers a compelling option. However, for intricate coding problems requiring nuanced solutions, Claude Code still holds a performance edge.

Final Thoughts

Google’s Gemini CLI is a bold step forward in AI-assisted development. Its generous free access and powerful features make it an inviting tool for many developers. As the technology matures, we can expect the coding capabilities to improve further and close the gap with competitors.
