Kleio — blazingly fast API driven ad server

add revenue
not latency

Modern marketplaces are only as good as they are fast. Unfortunately, popular ad servers take a heavy toll on site loading times. So we built our own – blazingly fast – and you can now use it, too.

Like everything from DoNoHarm, Kleio is slimmed down to the essentials and executed to perfection. You pay once, you run it, you own it forever, and it does its job with no additional latency to your marketplace and no issues with compliance.

The API-driven, self-hosted ad server sorts list of products using real time bidding, optimizing for expected revenue by incorporating conversion rates. Use it everywhere you show products, be it in search (Kleio supports Meilisearch out of the box), personalized recommendations, category listings, or any other list of products. And because you host it yourself, all data stays fully under your control.
