It's a very simple code base consisting of Azure Storage, a single Azure Function and a Cloudflare worker. It has its own domain, Cloudflare account and Azure services so can easily be picked up and open sourced independently to the rest of HIBP. It's entirely non-commercial without any API costs or Enterprise services like other parts of HIBP (I want community efforts to remain in the community). The data that drives Pwned Passwords is already freely available in the public domain via the downloadable hash sets.
