HappyKit is a feature flagging service for your Next.js applications.
The @happykit/flags package integrates with a single React hook. It works with all the different rendering strategies, like SSR, SSG, ISR and even hybrid approaches.
HappyKit supports dynamic rules, A/B Testing, can be used as a Kill Switch or used to gradually roll your new features out to your visitors.
It evaluates millions of feature flags a day.
HappyKit is ultra fast as it's built on Cloudflare Workers. This also makes it extremely robust. HappyKit is up if Cloudflare is up.
Building applications with Next.js is fun.
If you've ever built something with Next.js you might have been blown away by its simplicity. I certainly was.
But as you get closer to release, something becomes apparent. There are questions you're not able to answer: How do you release a feature without redeploying? How can you hide a feature quickly in case something goes wrong? Which marketing copy converts better? Can you roll out a feature gradually?
Now the fun stops.
Next.js is great for building applications, but there's a whole piece missing as you get closer to production. HappyKit wants to be that piece.
Your companion to run Next.js in production — with confidence.
So the fun can continue.
Hi, I'm Dominik. While working with Next.js, I realized that Next.js is enabling a paradigm shift. The frontend and the backend are moving closer together. This unlocks a completely new category of tightly integrated services.
But existing tools haven't noticed.
They still live in a world where frontend and backend are miles apart. Segregated by location of execution.
So I set out to build drastically better tools. To take advantage of these new capabilities.
