Frequently asked questions
What OPDS URL should I enter?
Use the OPDS feed address supplied by the server or catalog administrator. Some servers require a server-specific endpoint and credentials.
Does Sutra support every OPDS server?
OPDS servers vary in feed format, authentication, and acquisition links. Compatibility depends on what the server exposes; consult its documentation and test the feed.
Does generic OPDS sync my reading progress?
Generic OPDS catalog access does not guarantee reading-progress synchronization. Sutra's server-specific sync integrations are separate from generic OPDS.
Which formats can I read from OPDS?
Sutra supports EPUB, PDF, CBZ, and DRM-free MOBI files where the catalog exposes compatible file links. EPUB and PDF are free; full CBZ and DRM-free MOBI require Pro.
Can I read OPDS books offline?
A compatible book can be read offline after it has been downloaded or acquired to the device.
