• AI Commands: Use Ctrl+K to edit and write code with natural language, including terminal command generation
• Smart Features: Automatic typing mistake corrections, cursor position prediction, and quick question functionality for immediate code insights
• Composer: AI assistant with access to system tools for complex workflows - read/write files, execute terminal commands, and automate development tasks

Pros:

• Deep, context-aware codebase understanding
• Powerful natural language coding capabilities
• Highly effective debugging assistance
• Lightweight and fast performance
• Robust chat interface with integrated tools
• Seamless multi-line autocomplete
• Bring your own AI models for use with Chat

2. Windsurf: The Collaborative Agentic IDE

Windsurf, from Codeium, is a fork of Visual Studio Code that’s not just an AI-powered editor; it’s designed as an agentic IDE where developers and AI work together seamlessly. Its key feature called Cascade enables Chat and Write capabilities for agentic AI workflows. It keeps you in a “flow state” by integrating real-time collaboration with powerful AI assistance, focusing on true human-AI collaboration beyond traditional coding assistance.

Key Features:

• Cascade: Combines deep codebase understanding with real-time awareness for context-aware suggestions, debugging, and multi-file editing
• Flows (Agents + Copilots): AI that both collaborates like a Copilot and handles complex tasks independently as an Agent
• Version Control: Seamless Git integration for branch management, committing, and merging
• In-line Commands: Generate or refactor code using natural language (Cmd + I)
• Codelenses: One-click code understanding and refactoring from breadcrumbs
• Supercomplete: Smart analysis of next actions beyond basic code completion
• AI Integration: Easy AI settings adjustment via status bar and natural language terminal commands
• Context Features: @ mentions for files, directories, functions, classes plus highlighted code actions in Cascade panel

Pros:

• Powerful Cascade feature for AI-driven workflow
• Generous free credits for new users

Cons:

• Subscription-based pricing model
• Has access to a limited number of AI models, GTP4o, Claude Sonnet 3.5 and Cascade Base
• Paid service at $15/month

3. Visual Studio Code

The popular Visual Studio Code editor now comes with GitHub Copilot integration, providing access to powerful AI models like GPT-4 and Claude Sonnet 3.5 for intelligent code suggestions and pair programming capabilities.

Key Features:

• AI Extensions: Add AI capabilities through marketplace
• Chat and Copilot Edits: Use AI to write, refactor, and debug code
• Copilot Access: Limited free use available

Pros:

• Highly customizable
• Large extension ecosystem
• Free and open-source

Cons:

4. Cline: The AI Development Assistant

Cline is an autonomous coding agent that integrates directly with your IDE, capable of creating/editing files, executing commands, using the browser, and more with your permission every step of the way. It leverages Claude 3.5 Sonnet’s agentic coding capabilities to handle complex software development tasks step-by-step.

Key Features:

• Terminal Integration: Execute commands directly in your terminal and monitor their output as it works, letting it react to dev server issues and runtime errors
• File Management: Create and edit files with proactive error fixing - monitors linter/compiler errors to automatically handle missing imports and syntax issues
• Browser Testing: Launch headless browser sessions to click, type, scroll and capture screenshots + console logs for interactive debugging and testing
• Tool Creation: Extend capabilities through custom Model Context Protocol (MCP) tools that Cline can create and install for your specific workflow
• Multi-Model Support: Works with OpenRouter, Anthropic, OpenAI, Google Gemini, AWS Bedrock, Azure, GCP Vertex and local models through LM Studio/Ollama and Deepseek
• Context Management: Carefully analyzes file structure, source code ASTs, and runs regex searches to understand large, complex projects without overwhelming context

Pros:

• Handles complex development tasks step-by-step
• Integrates with existing development workflows
• Supports browser testing and interactive debugging
• Extensible through custom tool creation
• Tracks API usage and costs transparently

Cons:

• Requires VSCode for full functionality
• May need guidance for complex custom tool setups
