ZeroSSL

Get your site locked down in minutes and keep it that way. Start in the dashboard, add a domain, and pick the certificate scope you need—single host, multi-domain, or wildcard. Generate a CSR in-browser or upload your own, then choose how you want to prove control: place a small file on your server, add a DNS record, or confirm by email. As soon as the domain check completes, download the certificate bundle and key, follow the install guide for Nginx, Apache, or IIS, and run a quick health check to confirm the chain and hostname look good. This is the fastest path for bloggers, storefronts, or landing pages that just need to go live safely today.

Developers who automate everything can point their existing ACME client to ZeroSSL, create EAB credentials in the account panel, and schedule unattended renewals. Use a staging profile first to verify challenges, then roll the same config to production and let your cron jobs or systemd timers handle the rest. In CI/CD, add a job that requests or renews certificates on deploy, pulls the latest bundle via the API, and reloads your web server or reverse proxy. Running containers or Kubernetes? Wire issuance into your ingress controller, mount the secrets, and watch certs rotate without downtime. Prefer a hands-off approach? Install the bot on your server and let it request, validate, and refresh on a schedule you define. more
