✅ You want to switch between multiple LLMs - ✅ Privacy is a top concern - ✅ You're comfortable with configuration **Example Scenario:** ```bash Privacy-focused startup: - Can't send code to external APIs - Want to run models locally - Need flexibility to switch providers - Prefer open-source stack ``` ### Choose Kilo Code If: - ✅ You're building complex features - ✅ You want AI to manage entire workflows - ✅ You need parallel agent execution - ✅ You value spec-driven development - ✅ You want deep customization **Example Scenario:** ```bash Development team building a new product: - Need to build full-stack features - Want AI to handle planning + execution - Need to coordinate multiple agents - Value structured development approach ``` --- ## Real-World Examples ### Task: Build a REST API Endpoint **GitHub Copilot:** ```bash Developer types: // Create a GET endpoint for /api/users/:id Copilot suggests the route handler code Developer reviews and accepts Developer types: // Add error handling Copilot suggests try-catch blocks ``` **Continue.dev:** ```bash Developer: @codebase Create a GET endpoint for /api/users/:id Continue generates the complete handler Developer: Add error handling and validation Continue updates the code ``` **Kilo Code:** ```bash Developer: /spec "Build user API with CRUD endpoints" Kilo creates specification Developer: Approve spec Kilo creates tasks, implements, tests Developer reviews final result ``` ### Task: Debug a Production Issue **GitHub Copilot:** ```bash Developer pastes error message Copilot suggests possible causes Developer asks follow-up questions Copilot suggests fixes ``` **Continue.dev:** ```bash Developer: @logs Analyze this error stack Continue explains the issue Developer: @codebase Where could this originate? Continue searches codebase ``` **Kilo Code:** ```bash Developer: /mode debug "Fix the 500 error on /checkout" Debug mode analyzes logs Identifies root cause Proposes and applies fix Runs tests to verify ``` --- ## Migration Guide ### From GitHub Copilot to Continue.dev ```json // 1.
