Use cases
Who manages certificates with SSLBot
Indie developers and webmasters
You usually run more than one site. Install the Agent once and SSLBot takes over certificate requests, renewal, and deployment for every domain — no more per-site renewal calendars.
SMB IT and ops teams
Keep HTTPS uninterrupted without a dedicated certificate admin. Certificate status is visible, searchable, and auditable in one console — no handovers by word of mouth.
Multi-cloud and CDN architectures
The same domain may live on the origin, the CDN, and a load balancer at the same time. SSLBot deploys certificates to all of these targets, avoiding the classic "origin updated, CDN forgotten" expiry incident.
Security & ReliabilitySecurity,
Security,
by default.
Instant alerts on renewal failure
Alerts go out the moment a renewal or validation fails, leaving you enough time to act before the certificate actually expires. Channels: email / SMS / WeChat / WeCom
Pre-deploy validation with automatic rollback
Configurations are checked automatically before deployment; if deployment fails, everything rolls back to the previous state.
Least privilege
Certificate renewal, deployment, and sync require only minimal privileges — nothing more. Extreme simplicity brings reliability.

FAQ
Yes. sslbot supports single-domain, multi-domain, and wildcard certificates. You can request and manage all of these certificate types with one command.
Yes. You can use Let's Encrypt free certificates directly in sslbot; they renew and redeploy automatically before expiry, with no manual renew commands.
Yes. sslbot supports importing your existing certificates for unified management. You can also purchase various SSL certificates on the platform; multiple sources coexist in the same console.
sslbot continuously monitors certificate status and initiates renewal automatically before expiry; after a successful renewal it redeploys automatically.
Both DNS-01 and HTTP file validation are supported.
No. After configuration checks pass, sslbot hot-reloads the new certificate — deployment does not interrupt live traffic.
Yes. Add multiple domains in one place, choose deployment targets for each, and view all their certificate status together.
No. There is no need to open inbound ports; the sslbot Agent initiates connections to the console.
When a renewal fails, sslbot immediately alerts you through your configured notification channels, and the deployed configuration stays intact.
certbot and acme.sh solve only the "issue a certificate on this machine" step; they just run scripts and demand more expertise. sslbot covers the entire chain after issuance — centralized management, automatic deployment to multiple targets, failure alerts, and rollback — so it can be handed over to sslbot entirely.
About Us
The validity period of every SSL certificate keeps getting shorter. From March 15, 2026, newly issued SSL certificates will be limited to 199 days; from March 15, 2027, this drops further to 100 days; and by March 15, 2029, certificates will be capped at 47 days.
That means many times a year — dozens, even hundreds — you need to remember to log in to your servers, run renewal commands, reload services, and make sure the copies on your CDN and load balancers are updated too. Miss any step, and the cost is an unreachable website and a crowd of confused users.
We believe this job shouldn't be done by humans.
Certificate management done right means: nobody has to remember it, yet it is always correct.
Based on this idea, SSLBot chains discovery, renewal, deployment, and failure handling into one complete pipeline. It doesn't just request certificates from the CA — it delivers every issued certificate to wherever it belongs: Nginx, Apache, Docker, Kubernetes, CDNs, and load balancers. Issuing is only the starting point; keeping every copy valid is the goal.
SSLBot is built by engineers who have long been responsible for the stability of production systems.
