GrowthBook

GrowthBook is the most popular open source feature flag and experimentation platform, used at scale in production by thousands of companies.

By integrating GrowthBook Cloud with Vercel, you can view and manage all of your feature flags and experiments directly in Vercel. You can also enable Edge Config sync for near-zero initialization latency.

Installation is quick and easy. We will create a new account for you on GrowthBook Cloud and set you up with all of the required environment variables to quickly integrate our SDK into your code. If you enable Edge Config, we will also set up a webhook for you to keep feature definitions in sync automatically.
