Is TechLeads.Fyi - Technology Profiler safe?

Clean risk

TechLeads.Fyi sends your account email and the hostname of each analyzed site to its analytics server.

When you run a technology analysis from the popup, the extension posts your user id and email, the hostname of the active tab, and the list of detected technologies to analytics.techleads.fyi. Only the hostname is sent, not the full URL, and this happens when you trigger an analysis rather than passively.

Shared hosts - 13 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.
