AdPlugg

Ad server you download and run yourself

Revive Adserver is free because you run it on your own server, with no monthly fee or metered impression rate like AdPlugg's.

Hosted ad serving from under ten dollars

AdSpeed charges a flat $9.95 a month with no free tier at all, simpler to budget than AdPlugg's metered rate above 100,000 impressions.

Run your own ad server and keep the whole sale

AdButler has no free tier and starts at $179 a month, well past AdPlugg's free 100,000 impressions, but adds frequency capping and video.

An ad manager built for small local publishers

Broadstreet is built for local publishers managing several advertisers at once, starting at $299 with no free tier to test it on.

Ads on your site, paid out by Google

Google AdSense fills your unsold inventory with Google's own advertisers and pays you, rather than serving ads you already sold yourself like AdPlugg.

Ads without tracking, for developer sites

EthicalAds runs its own ad network with no tracking, free to join, for a developer site that would rather not sell its own placements.

Display ads with no traffic minimum to join

Infolinks has no traffic minimum to join and no fee to pay, since it sells the ads itself instead of serving ones you sold.
