We're excited to announce a new LaunchDarkly integration to bring low latency, global feature flags to your favorite frontend framework .

Feature flags help your team safely release new code and experiment with changes. Vercel Edge Config helps you instantly read configuration data globally, making it a perfect match for feature flag and experimentation data.

Vercel is the lowest-latency host for globally scalable applications using feature flags. By pushing data to every region, before any requests are made, you're able to read data from a Vercel Function or Edge Middleware immediately upon request.

Because data is pushed to every Vercel region at write time, we've seen most lookups return in 5 ms or less , and 99% of reads will return in under 15 ms.

This speed and global distribution make Edge Config great for:

A/B testing

Feature flags

Maintaining complex and dynamic redirects

Configuring and updating bespoke request blocking rules, without a redeploy
