How it works
Score intent before signup, then set the right free-tier limit
Visitor lands on your site
Signmark starts collecting intent signals in the background—no UX changes.
Capture pre-signup intent
We passively track a few simple signals—no forms, no CAPTCHA.
One API call at signup
You send IP + email (plus our session id). We respond in under 50ms.
One output: score + free-tier limit
You gate usage (not signup) with a per-signup limit that makes multi-account abuse unprofitable.
Lightning fast integration
Add Signmark to React
Install the SDK and wrap your app. Signmark generates a sessionId and collects pre-signup intent automatically.
1import { SignmarkProvider } from "signmark";23export default function App() {4 return (5 <SignmarkProvider apiKey="xxx">6 <Routes />7 </SignmarkProvider>8 );9}
Decide the free-tier limit on signup
On signup/login, call one backend helper with email + sessionId. Signmark extracts the IP from the request and returns a decision fast enough to run inline in your auth flow.
1const decision = await signmark.evaluate(req, {email, sessionId});
Save money without breaking UX
Legit users get a smooth experience. Abuse becomes expensive, and your infrastructure bill drops. You get a clear decision plus the reason behind it.

Built for ROI, not "security theater"
You don't need more hoops. You need limits that can't be gamed by creating more accounts.
Pre-signup intent scoring
We collect what users see, how long they spend on key sections, scroll depth, and navigation patterns—before signup—then turn it into an intent score.
Dynamic free-tier limits
Per-account caps are easy to bypass with multiple legitimate accounts. Signmark recommends a free-tier limit per signup so abuse stops scaling.
Signup-time IP + email signals
We automatically enrich your decision using IP and email signals at signup, layered on top of pre-signup behavior.
Clear savings & ROI tracking
See the impact in dollars: estimated infra saved, abuse prevented, and how much more free tier you can safely give to real users.
