Yea, it's abandonware - last update in the changelog was Sep 20, 2024 (https://updates.contentboom.pro/changelog) and the download links (to netlify) are broken in the admin for your account, if you have one. Agree, it was cool & had real promise and was a great alternative to the pro upsell / ai add-ons of most of the major seo plugins out there that aren't necessarily justified for every site.
