Alertmanager UI is useful for browsing alerts and managing silences, but it's lacking as a dashboard tool - karma aims to fill this gap. Starting with 0.7.0 release it can also aggregate alerts from multiple Alertmanager instances, running either in HA mode or separate. Duplicated alerts are deduplicated so only unique alerts are displayed. Each alert is tagged with names of all Alertmanager instances it was found at and can be filtered based on those tags (@alertmanager). Note that @alertmanager tags will be visible only if karma is configured with multiple Alertmanager instances.
