Continuous deployment

Split Testing is Netlify's built-in A/B testing feature -- splitting live traffic between different deploy branches using a cookie-based assignment, without needing a separate feature-flag or experimentation service for simple branch-level tests.

• Use Split Testing for straightforward branch-level A/B tests rather than standing up a separate experimentation platform for simple cases
• Confirm the cookie-based traffic split actually reaches statistical significance for your traffic volume before drawing conclusions from a short test
• Reach for a dedicated feature-flag service instead of Split Testing when you need more granular, per-user targeting beyond a simple branch split
