Official Presence CAPTCHA-replacement widget: the element and the embeddable presence.js runtime.
Human Presence Verification for Web Forms
Presence SDK — verify human presence before consequential actions execute.
Applications send intent and context. Presence verifies the person. Decionis decides whether execution proceeds.
This SDK is the subject-side handoff. It never accepts a tenant key.
Liveness assets and privacy
The production liveness step-up lazy-loads presence-stepup.js, requests camera permission, and
runs the bundled hash-pinned ONNX anti-spoofing model on-device. Frames are never uploaded. Serve the
published models/ and ort/ directories beside presence-stepup.js; missing or modified assets,
camera denial, and inference errors make the step-up unavailable and do not authorize the action.
Install
npm install @decionis/presence-widget
Or zero-code, straight from the CDN (what the Presence edge filter injects for you):
<script src="https://cdn.decionis.com/presence.js" async defer></script>
Thirty seconds to a verdict
<script src="https://cdn.decionis.com/presence.js" async defer></script>
<form action="/api/v1/checkout/confirm" method="post">
<presence-widget theme="auto"></presence-widget>
<button type="submit">Confirm transfer</button>
</form>
