Automate the full DigiCert certificate lineup available through regfish.
DV and OV through the same operational workflow
Issuance, deployment, and renewals in one tool
From API primitives to operable automation
If you do not want to decompose every TLS step into shell scripts or queue workers yourself, certbro is the shorter path from the regfish API to a stable Linux setup.
Why certbro
Less glue code, more production-ready TLS automation
Ordering and DCV in one flow
certbro orders certificates, provisions the required DNS CNAME tokens, and keeps watching issuance without splitting the flow across separate jobs.
DigiCert from DV to OV
The automation does not stop at standard DV certificates. certbro covers the full DigiCert product range at regfish, including OV certificates.
Stable deployment for web servers
The tool writes versioned artifacts and stable live/ paths and includes validation and reload support for nginx, apache, and caddy.
Unattended renewals
With certbro install, you set up hourly systemd renewals that reuse the local state for later runs.
