How it works
From file to link in three steps.

03 / Share
Send the URL
Paste it anywhere. The recipient downloads directly. That is the whole flow.
Architecture
One service. One volume. That is the stack.
Dopra's standard deployment intentionally avoids a complicated multi-service stack. One application, one database, one persistent volume, and nothing to babysit.
