## Code

```php
add_action( 'admin_bar_menu', function ( $bar ) {
    if ( is_admin() || ! current_user_can( 'manage_options' ) ) {
        return;
    }

    $bar->add_node( array(
        'id'    => 'wpide-third-parties',
        'title' => 'Third parties: ...',
        'href'  => '#',
    ) );
}, 95 );

add_action( 'wp_footer', function () {
    if ( ! is_admin_bar_showing() || ! current_user_can( 'manage_options' ) ) {
        return;
    }
    ?>
<script>
(function () {
    var link = document.querySelector('#wp-admin-bar-wpide-third-parties > a');
    if (!link || !window.performance || !performance.getEntriesByType) { return; }
    function hosts() {
        var own = location.hostname, map = {};
        performance.getEntriesByType('resource').forEach(function (r) {
            var h;
            try { h = new URL(r.name).hostname; } catch (e) { return; }
            if (h && h !== own) { map[h] = (map[h] || 0) + 1; }
        });
        return map;
    }
    function label() { link.textContent = 'Third parties: ' + Object.keys(hosts()).length; }
    window.addEventListener('load', function () { setTimeout(label, 1500); });
    link.addEventListener('click', function (e) {
        e.preventDefault();
        var map = hosts();
        label();
        var lines = Object.keys(map).sort().map(function (h) { return h + ' (' + map[h] + ' requests)'; });
        window.alert(lines.length ? 'This page loaded files from:\n\n' + lines.join('\n') : 'This page loaded nothing from other domains.');
    });
})();
</script>
    <?php
}, 99 );
```

## Notes

Uses the browser's resource timing list, so requests made after the click are not counted until you click again.
