HAProxy Cluster Manager puts a web console on top of HAProxy, so you publish services, issue certificates, and cluster nodes from forms instead of hand-editing haproxy.cfg. Publishing a service takes two inputs, the public URL and the backend address, and the wizard builds the frontend, backend pool, host condition, routing rule, HTTPS listener, certificate, and HTTP redirect, with a preview of the exact configuration before anything applies. Every change is rendered and checked with haproxy -c before it is written, and a failed reload rolls back to the previous file automatically. Certificates come from Let's Encrypt through acme.sh, using HTTP-01 or DNS-01 with about 190 DNS providers, and renewals reload HAProxy and push the new certificate to every node on their own. Any number of nodes share one virtual IP through Keepalived: configuration and certificates sync between them, only the node holding the address is editable, and the dashboard flags split brain, an unclaimed virtual IP, or a node running stale configuration. You can gate services behind basic sign-in or OIDC single sign-on enforced by HAProxy itself, watch traffic statistics and logs, take transition alerts by email, Pushover, or webhook, and expose Prometheus metrics and Home Assistant entities.
