In plain words

Piranhas was a tool that compared book prices across Amazon, Wordery, and the Book Depository to help readers find the best deals. The service has been discontinued due to operational challenges, including the loss of access to book retailer APIs and changes to affiliate programs.

Piranhas is no more Due to circumstances beyond my control, Piranhas has unfortunately been discontinued. Over the years, running this service has become increasingly difficult.

    Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their…
