Privacy-first age verification for the web

OpenAge runs face tracking, liveness checks, and age estimation on-device. Use it as a drop-in age gate with a checkbox-style widget, modal flow, or button binding.

At a Glance

Browser-side	Server-backed	UI
On-device face analysis	Optional WASM verification	Widget popup, inline embed, bind
No raw camera upload	Signed sessions and tokens	Normal, compact, invisible
Serverless soft gates	Hosted or custom backend	Auto, light, dark

Install

npm install @tn3w/openage

<script src="https://cdn.jsdelivr.net/npm/@tn3w/openage/dist/openage.min.js"></script>

Quick Start

CDN

<div class="openage" data-sitekey="ag_live_xxxx" data-callback="onVerified"></div>

<script src="https://cdn.jsdelivr.net/npm/@tn3w/openage/dist/openage.min.js"></script>
<script>
    function onVerified(token) {
        console.log('verified', token);
    }
</script>

npm

import OpenAge from '@tn3w/openage';

OpenAge.render('#gate', {
    mode: 'serverless',
    layout: 'inline',
    minAge: 18,
    callback: (token) => console.log(token),
    errorCallback: (error) => console.error(error),
});

Inline Embed

OpenAge.render('#gate', {
    mode: 'serverless',
    layout: 'inline',
    minAge: 18,
});

layout: 'inline' removes the checkbox shell and renders the verification panel directly in the container. The first verification step starts immediately after loading.

Bound Flow

OpenAge.bind('#buy-btn', {
    sitekey: 'ag_live_xxxx',
    callback: (token) => submitForm(token),
});

Modes

Mode	Backend	Use case
serverless	none	client-only soft gates
sitekey	OpenAge hosted	production verification
custom	your server	self-hosted verification

serverless keeps everything local and returns a client-signed token. sitekey and custom use a server session and a WASM VM for stronger checks.

Core API

OpenAge.render(container, params);
OpenAge.open(params);
OpenAge.bind(element, params);

OpenAge.reset(widgetId);
OpenAge.remove(widgetId);
OpenAge.getToken(widgetId);
OpenAge.execute(widgetId);

await OpenAge.challenge(params);

Runtime errors keep the popup open long enough to explain what happened. If no camera is available, OpenAge tells the user to plug one in and closes the popup automatically after 5 seconds.

Main Params

Param	Values
mode	serverless, sitekey, custom

Demo

• Static demo: https://tn3w.github.io/OpenAge/
• Local server demo:

cd server
pip install -r requirements.txt
python server.py

The repository also includes demo/, a minimal GitHub Pages build that loads the jsDelivr bundle for @tn3w/openage in inline embedded serverless mode.

Development

npm install
npm test
npm run build
npm run dev

Optional server:

cd server
pip install -r requirements.txt
python server.py

Formatting

pip install black isort
isort . && black .
