From official vendor APIs, release feeds, package sources (winget, Homebrew) and public release-notes pages — checked daily, source visible per product.

Do I have to install anything?

No. No agent, no scanner — you tell us what you run, we tell you when there are updates.

My tool isn't in the catalog?
