Bookhoarder is installable as a Progressive Web App — an icon on your home screen or dock that opens in its own window, no browser chrome around it.
Open Bookhoarder in a supported browser
Chrome, Edge, and most Chromium-based browsers on desktop and Android; Safari on iOS/iPadOS via Share → Add to Home Screen.
Install it
Use the browser’s install prompt (often an icon in the address bar), or the Add to Home Screen action on mobile Safari.
Open it like any other app
It launches standalone, themed to match Bookhoarder’s own colors.
What installing gets you
- A standalone window with no address bar or tabs
- An icon on your home screen, dock, or app launcher
- Nothing else — this is a shell, not offline reading
Why it’s shell-only
Bookhoarder is multi-profile, and which profile’s data you see is decided server-side on every request, from a cookie — not cached client-side. Caching pages or API responses would risk showing one profile’s library to another after a switch on a shared device, so the service worker only ever caches static, content-hashed assets (its own JS, CSS, fonts, and images). API routes, the reader, and every page navigation are network-first: the cache is only ever a fallback, and only when you’re genuinely offline.
