Is Readeon: A Patreon Reading Extension safe?

Clean risk

Readeon sends selected Patreon post content to its Koyeb backend when creating an EPUB.

When a user selects Patreon posts and chooses the EPUB download option, the extension posts the selected content and generated title and author fields to diplomatic-adelina-readeon-f63fb2a8.koyeb.app/api/download/epub. The backend returns a blob that the extension saves locally as the EPUB file.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
