Which sites use PubGalaxy?
The table below is every site we currently detect on PubGalaxy, ordered by authority so the strongest inventory is at the top. “Also uses” shows the other networks running on the same domain, which is the quickest way to see whether a publisher treats PubGalaxy as its primary partner or one line in a stack. First seen is the date the site first appeared in the network’s own seller file, so a 2023 date is a long-standing relationship rather than a recent test.
We currently detect 2,597 live sites on PubGalaxy. The figure moves nightly as the network publishes an updated seller file — sites are added when they first appear in it and retired when they have been absent for several consecutive runs.
Can I run PubGalaxy alongside another network?
Yes, and most publishers do. Of the sites listed here, the "Also uses" column shows how many carry a second or third network on the same pages. Check that network's own terms for exclusivity before stacking.
Which niches does PubGalaxy monetise best?
Its largest category by site count is Gaming. The niche panel above lists the full mix, which is a better guide to what the network actually buys than its marketing copy.
How do you know a site uses PubGalaxy?
From the network's published sellers.json file — the industry-standard record naming every publisher it is authorised to sell inventory for. That means a listing is the network's own declaration, not an inference from scanning pages.
How often is this list rebuilt?
Nightly. Seller files are re-fetched, differences recorded with a first-seen and last-seen date, and the site rebuilt. The most recent build finished 2026-07-28.
