PostHog joins the Vercel Marketplace

By Steven Van · 2026-02-10

PostHog joins the Vercel Marketplace, adding feature flags, experimentation and analytics via the Flags SDK.

PostHog is now available in the Vercel Marketplace as a feature flags, experimentation and analytics provider, announced in a Vercel Marketplace listing.

Declare flags in code using the 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

The integration can be installed from a project directory with vc i posthog, and Vercel offers a starter template, an e-commerce example using static page variants with middleware rewrites determined by the Flags SDK and PostHog.

Vercel

The platform for frontend developers — deploy, preview, and scale web apps and AI agents with zero config.
