Continue is an open-source AI code assistant that empowers developers to build custom autocomplete and chat experiences directly within their IDE.

Key features:

• Flexible model integration: Connect any AI models and context sources
• Customizable autocomplete: Get intelligent code suggestions as you type
• In-IDE chat: Ask questions and get code-aware responses without leaving your editor
• Context-aware: Leverages your codebase, documentation, and other sources for more relevant assistance
• Open and extensible: Build on top of Continue to create tailored AI coding experiences

Continue aims to keep developers in flow while coding by removing productivity barriers. Its plug-and-play system makes it easy to get started and integrate with your entire development stack. As an open platform, Continue allows teams to evolve their AI assistant capabilities as new innovations emerge.

Whether you're looking to accelerate development, reduce context switching, or become a leader in AI-assisted coding, Continue provides a powerful foundation for amplifying your development workflow with artificial intelligence.

Transform your VS Code into an intelligent development environment with AI assistants that understand your entire codebase. Unlike traditional autocomplete tools, Roo Code provides agentic AI capabilities that can plan, write, and fix code across multiple files simultaneously.

Key advantages over closed alternatives:

• Open-source and model-agnostic - Use any AI model including OpenAI, Anthropic, or local LLMs
• Deep project-wide context - Reads your entire codebase for intelligent multi-file refactoring
• Specialized modes - Switch between coding, debugging, and architecture modes on demand
• Task orchestration - Breaks down complex tasks and delegates to specialized AI modes
• Guarded execution - Approve or deny commands while maintaining full control

Advanced capabilities include:

• Multi-file editing with diff-based preservation
• Automated browser testing and verification
• Command execution with permission controls
• Fully customizable modes and behavior rules
• Enterprise-ready with self-hosted model support

Privacy-focused design ensures your code stays local unless you choose external APIs. Use .rooignore files to exclude sensitive content and run completely offline with local models for maximum security.

Perfect for both enterprise development and casual coding, Roo Code adapts to your workflow while providing the intelligence of an entire development team right in your editor.
