What it is
Humpback describes itself as an LLM paywall and analytics product for publishers. The apparent goal is to let sites see AI bot traffic, set policies for automated access, and move from unpaid scraping toward metered or permissioned use.
It belongs in this catalog because it matches the tollgate pattern directly, even if the current public evidence surface is still lighter than more established entries such as TollBit or Cloudflare.
Watchouts
The public positioning is clear, but dated official launch and adoption evidence is still thin, so this is best tracked as an emerging tollgate rather than a fully verified live program.
