Quick Setup (< 1 hour)

You can use Abby to create and manage feature flags and remote configuration variables for your web applications. It provides type-safe SDKs for React and Next.js, allowing you to test different features across multiple environments before deploying to production. The system includes built-in fallbacks to prevent downtime, debugging devtools for real-time flag monitoring, and supports both server-side rendering and static site generation. You can run A/B tests, gradually roll out new features to users, and modify app behavior without code changes.
