About Crossbar
Crossbar is a free, ad-supported cross-promotion network for indie websites. Install a single script tag to display a slim, dismissible bar (top on desktop, bottom on mobile) that cycles other builders' sites and occasional paid sponsors. You give exposure to earn exposure back from the shared pool, driving discovery from active builders without an ad account or spend. The network funds itself by selling roughly one slot in three to advertisers so the service remains free for participants.
