A 'competitor' to this would be GetSSL which is a pure-shell ACME client (plus OpenSSL and cURL) and can be executed on one host, but send verification tokens to remote systems (where you may not have cron access): > Get certificates for remote servers - The tokens used to provide validation of domain ownership, and the certificates themselves can be automatically copied to remote servers (via ssh, sftp or ftp for tokens). The script doesn't need to run on the server itself. This can be useful if you don't have access to run such scripts on the server itself, as it's a shared server for example. * https://github.com/srvrco/getssl https://github.com/srvrco/getssl
