Beyond Menu, a popular food delivery service in the US, adopted feature flags for gradual rollouts, instant rollbacks, A/B testing, trunk-based development and easier collaboration with beta users. They needed to evaluate feature flags and A/B tests on both server and client sides due to their use of Next.js and Vercel's App Router. The solution they chose was Hypertune in conjunction with Vercel's Edge Config, which provided seamless feature flag management without layout shifts. This setup enabled ultra-low latency reads at the edge, minimizing performance impact on the app and its conversion rate. Beyond Menu was able to roll out new features safely and reliably, with a robust developer and user experience, and with no negative effects on their app's performance or end-user experience. They plan to use Edge Config with Hypertune for more complex app configuration management and product analytics in the future.
