Plugins
Make Dalibre yours.
Plugins add what Dalibre doesn't do on its own: places to get books, metadata lookups, EPUB tools and actions on your library. Install them from Plugins › Marketplace in Dalibre's toolbar. Each one shows what it may reach before you allow it.
Safety
Plugins are code from strangers.
Dalibre treats them that way.
Sandboxed
Plugins run in a JavaScript engine inside Dalibre, not as programs on your computer: no shell, no other apps, and no files but two folders of their own, which uninstalling deletes.
Only the sites they name
Every request must go to a site the plugin lists, or it is refused. Your computer and home network are off limits unless it asks for them, checked after the address is looked up.
Nothing runs until you allow it
Installing shows what a plugin asks for: its sites, your local network, your library. An update that asks for more stays off until you allow that too.
Your library, on your terms
A plugin sees your books only if it asks to read your library. It never writes the library itself: it says what to change, and Dalibre shows you first unless you allowed it to change books. Actions never delete books.
Secrets stay secret
API keys and passwords you give a plugin go in your system's keychain, are masked in logs, and reach that plugin only.
No screens of its own
Plugins return data and Dalibre draws every screen, so a plugin can't fake a sign-in page or a system dialog. Calls have time limits: one that hangs is stopped, and Dalibre carries on.
The Marketplace's own plugins are written in Dalibre's repository. Community plugins are checked automatically when they are listed, not reviewed by hand: the sandbox and your consent protect you either way. The details →
