Jellybook
Jellybook is an iOS app for Jellycat collectors to catalogue, track, and share their collection. I built it for my fiancé and we run it together — our first iOS app, and close to 1,000 collectors signed up in its first month.
Overview
Jellybook gives collectors a searchable catalogue of thousands of Jellycats, a way to track what they own with notes and photos, a wishlist, and a community “Jellywall” to share their collection. The app itself is native Swift and SwiftUI.
The interesting part is the back end: it runs entirely on Cloudflare. Workers serve the API, D1 holds the data, R2 stores the images, and Workers AI plus Vectorize power image-based search, with Queues handling the background work. There are no servers to manage, it’s fast everywhere, and it costs almost nothing to operate.
