SSL monitoring for Fly.io apps
Fly.io's `fly certs` command provisions SSL automatically — but on custom domains with split DNS or apex A records, renewal can silently fail and the only signal is your customers. ManageCert hits your public hostnames daily and alerts before that happens.
Why ManageCert for Fly.io apps
Catches DNS-validation renewal failures
Fly's cert renewal requires DNS still pointing at the Fly target. If you change DNS, renewal silently breaks 90 days later. We watch both DNS and cert daily.
Edge + apex + subdomains all covered
Add every hostname you serve. We treat each independently — failure on one subdomain shouldn't hide behind a working apex.
Domain registration too
Fly handles the cert. We handle the domain registration daily so it never lapses on you.
SSL, domain expiry, DNS — daily, across all your domains.
SSL certificates
Expiry, issuer, SANs, chain validity, hostname match. Alerts at 30/14/7/1 days, plus immediate if invalid.
Domain registration
RDAP + WHOIS lookups daily. Alerts at 60/30/14/7 days. Catches lapsed-domain → squatter before it happens.
DNS records
A/AAAA/MX/CNAME/TXT/NS snapshot + diff. Catches mid-night MX flips before mail breaks for a week.
