01The problem
The failures that hurt most are boring and predictable: an auto-renew that silently failed, a certificate that did not renew, a DNS record someone changed, a backup job that stopped weeks ago. Existing tools cover a slice each, or cover everything but charge per site.
02The engineering
Warden checks certificate expiry, trust chain and hostname match, reads domain registrations from the registry over RDAP, and flags changes to A, AAAA, MX, NS, TXT and CAA records. It learns which certificate authorities issue for each domain and warns when a certificate shows up in the public logs from one that never has. Alerts go by email, Slack, Discord or a signed webhook, and the price is flat, not per site.
03The outcome
5kinds of check in one place, from certificates to heartbeats.
