Build less. Make more.

Feature Flags for your Next.js applications

Introducing HappyKit

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.

“HappyKit was a drop-in solution for us to start feature flagging our Next.js application, and most importantly, makes it possible for anyone on our team to control flags without requiring developer resources.”

“HappyKit allows us to get features perfect before we release them to our customers. We iterate until they are just right, then we simply switch them on for everyone.”

Who's behind HappyKit?

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.

This journey has led me to create HappyKit Flags, a feature flagging service for your Next.js applications. Sign up below to get started for free. I hope you'll enjoy it as much as I do.
