  -v $HOME/.tabby:/data \
  tabbyml/tabby \
  serve --model StarCoder-1B --device cuda

# Or without GPU
docker run -it \
  -p 8080:8080 \
  -v $HOME/.tabby:/data \
  tabbyml/tabby \
  serve --model StarCoder-1B --device cpu

IDE Extension: - VS Code: Install "Tabby" extension - Point to http://localhost:8080 - Start coding with completions

Screenshot-to-Code

# Install
git clone https://github.com/abi/screenshot-to-code
cd screenshot-to-code
npm install

# Set API key
export OPENAI_API_KEY=your-api-key

# Run
npm run dev

Usage: 1. Upload screenshot/design 2. Choose stack (React, Vue, HTML/CSS) 3. Get pixel-perfect code 4. Refine with prompts

Simple: Single endpoint Complex: Full CRUD API with auth

Best Practices

1. Prompt Engineering for Code

❌ "Add authentication"
✅ "Add JWT authentication to the user login endpoint with:
   - Email/password validation
   - Token expiration (24h)
   - Refresh token support
   - Error handling for invalid credentials"

2. Context Management

  • Continue/Cline: Use @file to reference specific files
  • Aider: Always specify files to edit upfront
  • Plandex: Let it analyze the codebase first

3. Review Before Commit

  • Always review AI-generated code
  • Run tests before accepting changes
  • Check for security vulnerabilities
  • Verify edge cases

4. Iterative Refinement

1. Generate initial implementation
2. Test and identify issues
3. Provide feedback with error messages
4. Refine until tests pass

5. Model Selection

  • GPT-4: Best for complex logic, architecture
  • Claude Sonnet: Fast, good balance
  • Claude Opus: Complex refactoring
  • GPT-3.5: Simple completions, speed

Common Use Cases

1. Refactoring

Tool: Aider, Continue Example: "Refactor UserController to follow SOLID principles"

2. Bug Fixing

Tool: Cline, Continue Example: "Fix the null pointer exception in line 45"

3. Test Generation

Tool: Aider, GPT-Pilot Example: "Generate unit tests for the PaymentService class"

4. Documentation

Privacy & Security

Data Handling

Cloud-Based Tools (Continue with OpenAI/Anthropic, Cursor, Sweep): - Code sent to third-party APIs - Subject to provider privacy policies - Check compliance requirements (GDPR, SOC 2)

Self-Hosted Tools (Tabby, Continue with Ollama, Aider with local models): - Code stays on your infrastructure - Full control over data - No external API calls

Best Practices

  1. Sensitive Code: Use self-hosted or local models
  2. API Keys: Never include in prompts, use environment variables
  3. Code Review: Always review AI suggestions for security issues
  4. Compliance: Check your organization's AI usage policy
