When feature flags
meet Next.js

Flaggish is a feature flag manager for Next.js. Ship a feature switched off on Friday, then turn it on from the dashboard without another redeploy.

One release, start to finish

Deploy on Friday. Relax all weekend.

Scroll through a real-world release of one feature, from merge to fully on.

  1. Merge it. Ship it switched off.

    The new checkout goes out with the rest of the release, hidden behind new-checkout. Customers still see the old one.

  2. Schedule the switch.

    Set the flag to turn on at 9am on Monday, so nobody has to be at a keyboard to launch it.

  3. Close the laptop.

    Nothing changes over the weekend. The code is live, the feature isn’t.

  4. It switches itself on.

    No deploy, no rebuild. The schedule flips the flag and the new checkout appears for the first quarter of your users.

    Rollouts coming soon

  5. Turn it up to everyone.

    Happy with how it’s doing? Slide the rollout to 100%. Still no deploy.

  6. Every change, on the record.

    Who switched what, and when, is in the flag history. If something looks wrong later, one switch rolls it back.

How it works

Three steps from merge to switched on.

Works in Server Components and Client Components.

  1. 1

    Install the SDK

    Add @flaggish/sdk to your Next.js project.

  2. 2

    Create a flag

    Name it in the dashboard and set it per environment.

  3. 3

    Check it in your code

    Ship the feature behind the flag, then turn it on when you’re ready.

// Server Component
import { getFlag } from '@flaggish/sdk'

export default async function CheckoutPage() {
  const newCheckout = await getFlag('new-checkout')
  return newCheckout ? <NewCheckout /> : <Checkout />
}

Example code. Function names are placeholders: see the docs for the SDK’s exact API.
