Shoutbox Widget

A live real-time shoutbox your visitors can post to. Messages are shared across all browsers — genuinely live. White or dark theme, fade-in messages, moderation and more.

Configure Your Shoutbox
☀️ Light
🌙 Dark
Fade-in messages
New messages slide up smoothly
Allow URLs
Let users post links (off = less spam)

Click Generate to create your unique shoutbox ID
Configure above and click Generate.
Live Preview
Configure and click Generate
Your shoutbox will appear here with a live preview
The preview is your actual live shoutbox — messages posted here are real.
How It Works
1
Click Generate — this creates a unique shoutbox ID for you. Every box has its own isolated message history that lives on Calcify's servers.
2
Check the live preview — this is your actual shoutbox. You can even post a test message from here to see how it looks.
3
Copy the embed code and paste it into your website — WordPress, Wix, Squarespace, or anywhere that accepts an iframe.
4
Keep your Shoutbox ID safe. If you want the same shoutbox on multiple pages of your site, use the same embed code. Each unique ID is a separate independent shoutbox.

Frequently Asked Questions
Is it genuinely real-time?
Yes — the shoutbox polls for new messages every 8 seconds automatically, so all visitors see the same messages within seconds of them being posted. No page refresh needed.
What happens if someone spams it?
Rate limiting kicks in at 20 messages per hour per IP address, with a 15-second cooldown between each post. Enable moderation mode if you want manual control over what appears.
Can I moderate messages?
Yes — enable the Moderation toggle before generating. All messages will be held in a queue until you approve them from the Calcify admin panel under Widgets → Shoutbox.
What if I lose my embed code?
Your shoutbox ID is shown in the embed code itself. As long as you have that ID, the same box and all its messages can be accessed. Keep a copy of your embed code somewhere safe.
How long are messages kept?
Messages are kept up to the limit you set (20 by default). When the box is full, the oldest message is removed when a new one is added. Boxes with no activity for 90 days are automatically deleted.
Can I have multiple shoutboxes?
Yes — each time you click Generate you get a new unique box. Embed different codes on different pages for separate independent shoutboxes.
