Features & Specs

  1. Automatic renewal

    Renews Let's Encrypt certificates when a third of their lifetime remains, so it keeps up as lifetimes shrink

  2. Auto-deploy to servers

    Installs renewed certificates on Nginx servers over SSH or via the agent, and rolls back if a reload fails

  3. Cloud and CDN deployment

    Deploys to AWS CloudFront and load balancers, plus Alibaba Cloud, Tencent Cloud and other cloud CDNs

  4. Open-source deployment agent

    Outbound-only agent: no open ports and no stored SSH credentials; supports Nginx, 1Panel and Nginx Proxy Manager

  5. Certbot and acme.sh takeover

    The agent discovers existing Nginx sites and lets you choose which ones LapseZero manages

  6. DNS delegation

    A one-time CNAME per domain; no DNS API keys to hand over, wildcard certificates included

  7. Certificate monitoring

    Watches the certificates on your public HTTPS sites and alerts you before they expire

  8. Notifications

    Email, Webhook, Slack, Telegram, DingTalk, Feishu and WeCom alerts

Questions & Answers

As answered by people managing LapseZero.
  1. What makes LapseZero unique?

    LapseZero doesn't stop at renewal. It issues and renews Let's Encrypt certificates, then installs them where they are actually served:

    • Nginx servers, over SSH or through a small open-source agent that only makes outbound connections
    • AWS CloudFront and load balancers, plus Alibaba Cloud, Tencent Cloud and other cloud CDNs
    • Existing Certbot and acme.sh sites, which the agent discovers so you can choose which ones LapseZero takes over

    Your DNS credentials stay with you: a one-time CNAME when you add a domain is all LapseZero needs for every later renewal.

  2. Why should a person choose LapseZero over its competitors?

    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.

  3. How would you describe the primary audience of LapseZero?

    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.

  4. Which are the primary technologies used for building LapseZero?

    • TypeScript, Next.js and React for the web app
    • Fastify, PostgreSQL (Prisma), Redis and BullMQ for the API and job queues
    • Go for the open-source deployment agent
    • ACME protocol with Let's Encrypt for certificate issuance
  5. What's the story behind LapseZero?

    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.
