Ad Swap

Free ad exchange for small sites. Show one ad, get shown on someone else's.

How it works

1

Paste one embed tag on your site — it shows a random member's ad. It's a plain <iframe>, so it works even if your site has a strict Content-Security-Policy.

2

Submit your site below with a short tagline and optional logo.

3

Once we see the widget live on your site, we approve you into the pool and your ad starts showing on other members' sites.

What the ad looks like

Light or dark

Follows your visitor's system theme by default. Force one explicitly with &theme=dark or &theme=light on the iframe (or data-theme="dark"/"light" if you're on the older script-tag embed).

Light

<iframe src="https://ad-swap.web.app/frame.html?site=YOUR_ID&theme=light" style="border:0;width:300px;height:130px;max-width:100%;" loading="lazy" sandbox="allow-scripts allow-same-origin allow-popups" title="Ad"></iframe>

Dark

<iframe src="https://ad-swap.web.app/frame.html?site=YOUR_ID&theme=dark" style="border:0;width:300px;height:130px;max-width:100%;" loading="lazy" sandbox="allow-scripts allow-same-origin allow-popups" title="Ad"></iframe>

1. Add this to your site

This is your embed code, ready now — paste it on your site before submitting below. We can't approve you until we see it live there.

2. Submit your site

Once the code above is live on your site, fill this out.

This is the actual embed widget running right here on this page — the same one you'd paste on your own site.
