Is Chrome extension source viewer safe?

Clean risk

View and download Chrome Web Store extension source code without installing the extension.

This extension adds tools on Chrome Web Store pages to view an extension’s source code or download it as a ZIP file. The viewer includes file filtering, content search, code formatting, syntax highlighting, hashes for individual files, image previews, embedded ZIP viewing, and permalinks to files or search results. Optional settings add support for viewing Opera, Edge, Firefox, and Thunderbird add-ons, plus source viewing from extension links or CRX downloads.

What this publisher told the store about itself, and the other listings that told it the same thing.

Same store account

4 other listings published from this account, 1.6M+ users between them, none of them carrying a finding.

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.
