Optimized for Next.js

No juggling different SDKs for the client and the server. Install one TypeScript SDK that "just works" on both the client and the server and is ready for the new App Router paradigm with React Server Components.

No cumulative layout shift, no flickers, no out-of-sync client hydration, no page load delay. Instantly initialize the SDK on the client from server props on the first render.

No latency in Vercel's edge environment. Instantly initialize the SDK on the server from Vercel Edge Config.

No flaky preview environments shared by all your developers. Get an isolated branch in Hypertune for every Vercel Preview Deployment to safely test flag changes.

Custom, powerful targeting and A/B testing

No struggling to target the users you want. Use custom properties in your flag targeting.

No stitching together feature flags and A/B tests in your code. Embed A/B tests directly in your flag targeting logic, to seamlessly roll out and A/B test new features.

No struggling to A/B test multiple features at once. Reuse a single A/B test across multiple flags to roll them out in sync and measure their cumulative impact.

No ceilings on your targeting logic. Express any condition with our powerful configuration language.

Git version control and isolated branches

No painfully debugging what combination of flag changes broke your product. A single Git history for all your flags together to pinpoint and revert bad changes.

No shared "preview environment" that drifts from production. Create isolated branches in Hypertune to safely test flag changes. Get a Hypertune branch for each Vercel Preview Deployment.

No accidentally breaking production. Create pull requests and require approvals before merging them.

Git version control

End-to-end type-safety

No "Uncaught ReferenceError: flag is not defined". No raw strings, typos or struggling to find flag references. Get auto-generated type-safe code for all your flags.

No polluting your codebase with stale flags. Remove their definitions, regenerate the code and fix all the type errors to safely remove usages.

No accidentally using invalid properties in the flag targeting UI. Define custom targeting properties in your strongly typed schema for type-safe access in the targeting UI.

End-to-end type-safety
