Our SDKs automatically detect the environment from your API key prefix. Just swap the key value.

Environment Variables

Store keys in environment-specific files (.env.local, .env.production) for automatic switching.

CI/CD Pipelines

Configure secrets in your CI/CD platform (GitHub Actions, Vercel, etc.) for each deployment environment.
