Expose your local services to the internet securely and easily.

Configuration:
  First time: Run 'drip config init' to set up server and token
  Subsequent: Just run 'drip http <port>' or 'drip tcp <port>'

Examples:
  drip config init                  # Set up configuration
  drip http 3000                    # HTTP tunnel
  drip tcp 5432                     # PostgreSQL tunnel
  drip http 8080 --subdomain myapp  # Custom subdomain

Features:
  ✓ TCP over TLS 1.3 (secure and fast)
  ✓ HTTP and TCP tunnel support
  ✓ Auto-save configuration
  ✓ Custom subdomains
  ✓ Authentication via token`,
