Is Competitive Companion safe?
Parses competitive programming problems and contests and sends the parsed data to compatible tools.
This extension works on supported competitive programming problem pages when you click its green plus icon or use its keyboard shortcut. On supported contest pages, it can parse all problems in the contest at once and send the parsed data to tools such as CP Editor and CPH, with localhost access listed in its permissions.

Shared hosts - 5 hostnames
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.
