As answered by people managing Obsidian and LapseZero.
LapseZero's answer:
LapseZero doesn't stop at renewal. It issues and renews Let's Encrypt certificates, then installs them where they are actually served:
Your DNS credentials stay with you: a one-time CNAME when you add a domain is all LapseZero needs for every later renewal.
LapseZero's answer:
Certbot and acme.sh renew certificates well, but each server renews on its own and every CDN or load balancer needs its own deploy hook script. LapseZero renews once and pushes the certificate to every target from one dashboard, checks that the new certificate is live, and notifies you when something needs attention.
With Let's Encrypt's default lifetime dropping to 64 days in 2027 and 45 days in 2028, renewals and deployments happen far more often, so fewer scripts to maintain matters more. You can start free with 3 domains, 5 deployment targets and 5 certificate monitors, no credit card required.
LapseZero's answer:
Developers, sysadmins and small DevOps teams who run their own Nginx servers or serve sites through AWS CloudFront, load balancers or cloud CDNs, and who would rather not maintain renewal and deploy scripts across all of them.
LapseZero's answer:
LapseZero's answer:
LapseZero started with my own day-to-day work. I manage a lot of domains at my company, along with their production and test servers, and more and more of them need certificates. As certificate lifetimes kept getting shorter, renewing and reinstalling them turned into constant maintenance, and it was easy to forget one.
So the first thing I built was SSL certificate expiry monitoring, to make sure nothing slipped through. Monitoring only tells you something needs doing, though, so the next step was to renew certificates automatically and deploy them to every server that uses them. That became the core of LapseZero.
