About SponsorKit
SponsorKit lets a website owner monetize with sponsor placements by pasting a single script tag into their HTML. The creator sets prices, marks slots on a calendar with a minimum bid, and brands buy the space directly on the site. Each slot opens and closes by itself on its scheduled dates, each sponsor is reviewed with one click, and funds arrive the day a slot goes live. The script is 2.1 KB gzipped, has no dependencies and no build step.
The widget renders server-side so it still loads for visitors using ad blockers, and it sets no tracking cookies. Layouts include a badge bar, spotlight, carousel and list, and positions include a top banner, sidebar, footer and in-article placement, with a configurable number of slots. The site has a playground where visitors can flip these options and preview checkout math. Its pitch is infrastructure for direct sponsorships rather than an ad network.
