import re
import dns.resolver

def validate_email(email: str) -> bool:
    pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'
    if not re.match(pattern, email):
        return False

    domain = email.split('@')[1]
    try:
        dns.resolver.resolve(domain, 'MX')
        return True
    except:
        return False

Pricing

Pros and cons

Pros:

• Works in the IDE you already love

• GitHub integration (issues, PRs)
• Free for students

Cons:

• Lower quality than Claude-based tools
• Multi-file editing is still in beta
• Less control over models

Who it's for

✅ Anyone who doesn't want to change IDEs ✅ Teams on GitHub Enterprise ✅ Students (it's free)

Cline

What it is

Cline is an open-source extension for VS Code. It's BYOK (Bring Your Own Key) — you pay the model providers directly.

Features

Key features:

• Autonomous coding — the agent completes tasks on its own
• Tool use — runs commands, uses a browser, works with files
• Any model — OpenAI, Anthropic, DeepSeek, Ollama
• Full control — you see and approve every action

Models: Any model available via API (Claude, GPT, DeepSeek, Llama)

Example

[Open the Cline sidebar]
"Add unit tests for the UserService class, covering all public methods"

Cline:
1. Reads UserService
2. Proposes a plan: "I'll create 5 tests for methods X, Y, Z..."
3. [You approve]
4. Creates the tests
5. Runs pytest
6. Fixes errors
7. "Done. All 5 tests passing."

Pricing

Typical month: $10-50, depending on usage

Pros and cons

Pros:

• Full control over every action
• Any model (including local ones)
• Open source (you can audit the code)
• Flexible pricing (you pay for what you use)

Cons:

• You have to set up API keys
• Steeper learning curve
• Less "magic" — more control means more work

Who it's for

✅ Experienced developers ✅ The privacy-conscious (local models are an option) ✅ Anyone who wants to understand what's going on under the hood

❌ Beginners (harder to set up) ❌ Anyone who wants something that "just works"

Claude Code

What it is

Claude Code is Anthropic's official CLI for coding in the terminal.

Features

Key features:

• Terminal-native — works in any terminal
• Project context — understands your project's structure
• File operations — creates, edits and deletes files
• Command execution — runs commands after you confirm them

Model: Claude Sonnet 4.6 (default), Opus 4.6 (for complex tasks)

Example

$ claude-code "Refactor the logging module to use structured JSON logs"

Claude Code:
→ Analyzing project structure...
→ Found: src/utils/logger.ts

Plan:
1. Update logger.ts to use pino instead of console.log
2. Add structured log format
3. Update all import statements (found 12 files)
4. Add pino to package.json

Execute? [y/n]: y

→ Installing pino...
→ Updating logger.ts...
→ Updating imports in 12 files...
→ Running tests...

✓ Completed. All tests passing.

Pricing

Typical month: $20-100, depending on usage

Pros and cons

Pros:

• Native terminal integration
• The best model for coding (Sonnet 4.6)
