feature flags guy @vercel, made https://t.co/gSLMbcfh2V, creator of Edge Config

Today we launched our new Flags SDK docs. I love the playground. It allows switching multiple flags, and yet the page itself remains static. Pick any combination of flags and reload. There's no layout shift

I gave a workshop about the Flags SDK at Vercel Ship this week, and the companion app we built is such a great walkthrough of the Flags SDK for Next.js. The recording of the talk should be available online soon too.

Excited to have Hypertune on our Vercel Marketplace. 1. Open the Flags tab in your project on the ▲ dashboard.2. Connect Hypertune.3. You got feature flags now :).
1/ Excited for Hypertune to join the Vercel Marketplace as a native app. You can now install it directly from the Flags tab of your Vercel dashboard in one click, and start using feature flags and running experiments in minutes.

You can now change the state of your flags without redeploying your app! And it's still ultra fast and highly available. This is of course a basic setup you will outgrow, at which point you can switch to a real flag provider. See for adapters.

Back your flag by reading from our global data store called Edge Config instead of declaring the value in code. Think of Edge Config as a config file you can change without redeploying your app. It's available at insanely low latency and has extremely high availability.

You now have a free, homegrown feature flagging service!. There are tradeoffs though.• changing flag state requires redeploying.• can not change flag state across deployments.• no UI to edit flags. This is where Edge Config can help….

This system has a few nice properties.• decouple merging to main from releasing features.• able to test features in production before they go live.• flags evaluate instantly, as it's all local.• the flag "service" can't go down, it lives in your code.• flag usage is free.

3. Override. You can now merge to prod and your feature will remain hidden for users. But how do you actually test your feature before releasing?. Use the Flags Explorer in Vercel Toolbar to override the flag. This will turn the flag on for your own session only, so you can test

2. Use your flag. The flag we created earlier has no feature flagging service behind it. It's basically just an async function configured to return false. Call your flag like any other async function to evaluate it

How to use feature flags for free. 1. Create flag. Declare your flag in code using the Flags SDK, and configure it to always return false. We'll get to why this matters later.
