Is NopeCHA: CAPTCHA Solver safe?

Clean risk

NopeCHA: CAPTCHA Solver sends detected challenge media and page context to api.nopecha.com for CAPTCHA solving.

When the extension detects supported CAPTCHA challenges, it sends challenge-specific payloads and page context to NopeCHA's API so the service can solve them. The same workflow can also send optional browser observability details, such as screen and fingerprint-related values, to the same API when enabled by its scheduler.

Shared hosts - 4 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.
