You can now install LaunchDarkly from the Vercel Marketplace and evaluate your first flag in minutes. Start on our free Developer plan and upgrade when you need to, all managed from Vercel. Find us under the Flags or Experimentation category, click install, and in a few clicks, you have a LaunchDarkly account, a project, and SDK keys already wired into your Vercel project. Install, billing, and key management all happen inside the Vercel dashboard.
This launch is a partnership we're excited about. Feature flags have become part of how modern web teams ship, and Vercel has made them a first-class concept in its platform, with a dedicated Flags category in the Marketplace, a Flags Explorer in the Vercel Toolbar, and the Flags SDK. Vercel shows feature flags from third-party providers like LaunchDarkly natively in the dashboard, letting you reuse your Vercel account to sign in directly, and LaunchDarkly extends that foundation into production with runtime control—targeting, progressive rollouts, experimentation, and automated,rollback.
Our take has always been that flags shouldn't be something you bolt on after your first bad deployment. They should be there from the first commit. Putting LaunchDarkly natively inside Vercel is what that looks like in practice.
What the integration does
The account and key plumbing that usually sits between "I want feature flags" and "My code is evaluating one" is gone. Here’s what happens when you install LaunchDarkly from the Marketplace:
- We create a LaunchDarkly account and project for you automatically, with Development, Preview, and Production environments that mirror Vercel's.
- Each Vercel native integration environment gets its own SDK key and client-side ID, synced into your Vercel project as environment variables. In LaunchDarkly, your preview deploys will have their own dedicated environment.
- You sign in through Vercel SSO, so there's no separate login to manage. Jump into the full LaunchDarkly app anytime by clicking "Open in LaunchDarkly."
From there, you drop the SDK into your app, read the key from the environment variable that's already there, and start evaluating flags. You skip the usual ritual of copying keys between dashboards and double-checking which one belongs to which environment.
Your flags and projects sync back into Vercel too, so your team can see what exists without switching tools. Rotate your SDK keys, and the environment variables are updated for you.
"Every project should start with feature flags—they're what let you and your agents ship at full speed and still control what happens in production. Vercel just made that the default path: a few clicks and LaunchDarkly is wired in before your first deploy."
—Jonathan Nolen, SVP Product, LaunchDarkly
What you get
Fast flags, globally
We've collaborated with Vercel on global config evaluation since 2023, when we launched our Global Config integration for Enterprise customers. With the Marketplace integration, that capability comes with self-serve plans, too: Sync your flag targeting to Vercel Global Config and your flags evaluate in Middleware and Vercel Functions with the config sitting next to your code, without a network call back to LaunchDarkly.
Start small, without a ceiling
Simple today doesn’t mean limited tomorrow. The marketplace listing gets you flags in minutes, but the project you create from Vercel is a full LaunchDarkly project. It's the same platform teams use for progressive rollouts, guarded releases that can roll back automatically when a metric regresses, experimentation, and AI config management. You grow into that depth without having to migrate off what you started on.
One invoice, same LaunchDarkly
Billing runs through Vercel, so LaunchDarkly shows up on your existing Vercel bill. It's the same product at the same pricing as signing up with us directly. Start on our free Developer plan and upgrade when you need to, all managed from Vercel.
Meeting you where you build
More and more, tools get adopted from inside the platforms where people already build. So we're putting LaunchDarkly in reach: native in the Vercel Marketplace, available through our MCP server for AI coding agents, and integrated with the editors and workflows where developers already live. Wherever you build, flags should be a few clicks away.
The Vercel partnership is the clearest expression of that so far. Two platforms that both believe shipping should be fast and reversible, now connected so you don't have to choose between moving quickly and staying in control.
"Feature flags are how the best frontend teams ship without holding their breath, and LaunchDarkly is the platform that made that discipline real—not just an on/off switch, but progressive delivery, experimentation, and measurement teams can trust. Making it native in the Marketplace puts that depth a few clicks away for every team building on Vercel."
—Hedi Zandi, Head of Vercel Marketplace
How to get started
Head to the LaunchDarkly listing on the Vercel Marketplace and click Install. Docs for the integration, including the Global Config setup, are in our Vercel integration documentation.
The Vercel native integration creates a fresh LaunchDarkly account for you—the fastest path to your first flag, plus project, flag, and SDK key syncing.
Already using LaunchDarkly?
Connect your existing account during install instead of creating a new one. With this path, your flag targeting is synced to Vercel Global Config.
The gap between wanting feature flags and shipping behind one just got a lot shorter. Happy shipping!
