From a packed house in NYC to screens across the globe, one message from Vercel Ship 2025 resonated with over 50,000 developers: the web is evolving, and so are the threats. Sophisticated bots are a direct threat to your applications, users, and bottom line. CAPTCHA’s tax on users degrades their experiences while ultimately failing to stop modern adversaries.
That is why we are thrilled to announce a strategic partnership between Kasada and Vercel. Together, we are releasing Vercel BotID, a zero-friction, invisible security layer integrated tightly with Vercel’s platform – placing Kasada’s battle-tested bot defense directly into the workflows of millions of developers, to serve uninterrupted user experiences.
Kasada’s Expertise: Proven Defense Against Advanced Threats
For years, Kasada has been the definitive choice for businesses that can’t afford to lose the battle against bots. We are the silent guardians for many of the world’s most recognized and targeted brands in sportswear, streaming, retail, fintech, and travel. Publicly, we’re proud to protect leaders like Hyatt Hotels, Crocs, Canada Goose, Wizz Air, and Sportsbet.
Our track record has led to a powerful trend: 85% of our customers tried other solutions first. They come to us when nothing else works. And they stay when they see the bad bot traffic disappear for good.
Vercel sought a level of efficacy that Kasada provides its global customer base for its own platform and, now, for its community through our partnership.
Introducing Vercel BotID, Powered by Kasada
“With BotID, we’ve made the most advanced bot defense as easy to use as any modern developer tool,” said Sam Crowther, CEO and Founder of Kasada. “This partnership puts our bot protection in the hands of Vercel’s developer community, without a learning curve or end-user disruption.”
How Vercel BotID Delivers Invisible Protection
BotID sits at the edge of a Vercel deployment, allowing legitimate human users through while blocking bots before they reach the application.
It’s easy to get up and running.
// 1. Install the package
npm i botid
// 2. Wrap your Next.js config to enable edge rewrites
import { withBotId } from 'botid/next';
export default withBotId(nextConfig);
// 3. Mount the client-side detector in your app layout
// Place this high in the tree to initialize before navigation
import { BotIdClient } from 'botid/react';
<BotIdClient protect={['/checkout', '/api/submit']} />
// 4. Verify requests server-side
import { checkBotId } from 'botid/server';
const botIdResult = await checkBotId(req);
nueToApp(request);
In return for a few minutes of work, you get real, impactful outcomes:
- Easy to Use & Invisible: It’s a drop-in component with simple configuration for the developer, and runs silently behind the scenes with no CAPTCHAs or challenges, preserving the user experience.
- Highly Effective with a Clear Verdict: Our defense combines deep client-side interrogation with server-side ML. It returns a simple pass/fail verdict, rather than ambiguous, confusing scores.
- Hard to Bypass: We use randomized, real-time obfuscation and mutate detections on every page load, dramatically increasing the cost and effort for adversaries like Solver Services to re-tool.
“Kasada shares our commitment to helping developers ship faster without compromising security,” said Malte Ubl, CTO of Vercel. “BotID enhances Vercel’s Bot Management by eliminating friction for developers and end users while delivering a security layer we trust for our most critical applications.”
