Widget & SDKs
Put the universal @beat clock anywhere — a one-line website embed, plus drop-in SDKs for Python, PHP, JavaScript, Unity and Unreal.
Embed the live @beat clock
Copy, paste, done. The clock ticks locally and syncs to the server — no account, no cookies, no tracking. Works on any site, even plain HTML.
@beat in your browser
A small Firefox extension: the current beat on the toolbar icon, and a clock with a converter one click away.
Sigelith — @beat clock
- The toolbar icon shows the current beat — 1000 beats a day, the same moment everywhere.
- One click opens a live clock to the centibeat (@523.45) with UTC time, and a converter between your local time and @beat.
- The time is computed on your computer; now and then the extension asks sigelith.org to correct clock drift — nothing else. No tracking, no account.
Timestamps for WordPress
A WordPress plugin: stamp files from your Media Library with one click and show the timestamp badge under them in your articles.
Sigelith Timestamp
WordPress 6.0 or newer, PHP 7.4 or newer · GPL-2.0-or-later
Get it on WordPress.org
- “Stamp with Sigelith” next to each file in the Media Library — or, if you choose, every new upload in the background.
- The badge appears under File blocks and on attachment pages, and anywhere with a shortcode. It disappears when the file is replaced.
- Only the file's SHA-256 fingerprint leaves your server — never the file, its name or your site's address. No tracking, no account.
Or search for “Sigelith Timestamp” under Plugins in your WordPress dashboard.
Proof of handover for your shop
Plugins for WooCommerce and PrestaShop: the courier scans a small label, the buyer shows a pickup code or confirms on the phone, and your shop receives the evidence with a public timestamp and checks it itself. Works with any carrier.
Sigelith Delivery for WooCommerce
WordPress 6.2 or newer, WooCommerce 8.0 or newer, PHP 7.4 or newer · GPL-2.0-or-later
Sigelith Delivery for PrestaShop
PrestaShop 8.1 or 9, PHP 7.4 or newer · AFL-3.0
- A small label for each parcel; the buyer gets the pickup code by e-mail — as text, as a QR code and as a link that opens it on the phone. Nothing to install.
- The courier’s app sends the evidence straight to your shop, which checks every signature and stamp itself — the cosigners of the public log too — and marks the order.
- Only SHA-256 digests leave your shop — never an order, a name or an address. No account, no fees.
Both in 11 languages. Couriers use the free Sigelith Courier app; buyers need no app.
