Prices checked 12 Oct 2026 on each vendor's public pricing page. US dollars, monthly billing, list price divided by the certificates, endpoints, monitors or sites the plan includes. Oh Dear is a full monitoring suite priced per site, so it is not a like-for-like SSL price. Cert Spotter endpoints can be wildcards. Alert channels are the ones each vendor lists for that plan.
