Sutra — a reader for your DRM-free books and comics. Connect your Kavita, Calibre, Komga, or WebDAV server, or a supported OPDS catalog. Load local files, read manga and comics panel by panel, track your reading stats, and auto-scroll through long reads.
Connect Kavita, Calibre, Komga, or any OPDS server, plus WebDAV hosts like Synology. Everything works on your local network, with no cloud middleman.
Project Gutenberg's 75,000+ public-domain classics and Standard Ebooks' typeset collection, no server required.
Sort by Recently Read, Title, Author, or Date Added. Books with no artwork get a clean title-and-author cover instead of a blank tile.
Series appear as grid tiles, and books from the same series stack with a count. Collections open in a consistent grid, and you can rename your own. Favorites is built in, always first, with its own heart-marked card.
Themes, fonts, bookmarks, and in-book search. Open files from your device's file manager or any share sheet, no server required. Landscape on iPad and Android tablets shows a two-panel facing-page spread, and iOS adds authentic page-curl turns.
Panel Mode and right-to-left manga reading are available on iOS and Android for supported content. Full CBZ reading requires Pro. CBZ page streaming is available on supported Kavita and Komga setups; Komga also requires the account's Page Streaming permission.
Set your pace and let the page flow. Swipe up or down to adjust speed on the fly, or tap to pause and resume. Perfect for hands-free reading.
A dedicated e-ink display mode keeps reading crisp on e-ink screens.
Highlight in color, add notes, and look up words in the built-in dictionary. On iOS, double-tap a word to define it, and footnotes open in a sheet so you never lose your place.
Reading progress syncs back to your Kavita and Komga servers. On iOS, iCloud also keeps position, bookmarks, and highlights in step across your devices, and on Android, Export keeps your data portable.
A Stats tab tracks your reading time and progress across your library. On iOS you also get a streak, a swipeable activity chart, and time-remaining estimates that learn your speed for each format.
A limited preview may be available for supported CBZ and comic-shaped MOBI files. Full CBZ and DRM-free MOBI reading require Sutra Pro.
Features vary by platform and file format; the table identifies the supported tier. Pro is a one-time purchase through each platform's store. In the US, Sutra Pro is $6.99 USD on the App Store and Google Play. Prices may vary by region; check your store for current local pricing.

Sutra works with files you own outright — no DRM, no lock-in. We've put together a curated list of stores and publishers that sell ebooks the right way: you pay, you download, you keep the file forever.
Browse our curated list →Reading EPUB and PDF stays free. Pro is a single payment with no subscription, so buy it on the platform you read on.
Purchases are per platform. Apple and Google handle billing separately, so Pro on iOS does not carry over to Android.
