PostHog is now available in the Vercel Marketplace as a feature flags, experimentation and Analytics provider.
With this integration, you can now:
- Declare flags in code using Flags SDK and the @flags-sdk/posthog adapter
- Toggle features in real time for specific users or cohorts
- Roll out changes gradually using percentage-based rollouts
- Run A/B tests to validate impact before a full release

Create a flags.ts file with an identify function and a flag check:
