Squabble's web app already shows your library and guild activity, but it doesn't play audio yet — for any book, from any source. Streaming an Audiobookshelf book straight from your browser is a coming-soon feature, not something you can do today.
What works today
Your library list, progress, notes, and guild activity are all visible on the web Also on web, including books you've downloaded from your Audiobookshelf server on mobile — you can see them and track where you are in each one. What the web app doesn't do yet is play anything back. Connecting a server, browsing its library, downloading a book, and listening are all mobile-only today — see Browsing and downloading for how that works on your phone.
What's coming
Coming soon to web In-browser streaming will let you connect your Audiobookshelf server from the web and play a book directly from it — no download to a device required, and no separate setup beyond the server connection itself. Seeking, chapters, and your listening position are planned to work the same way they do on mobile, with progress staying in sync with both your server and your guild.
