Gravity Sync is a shell script that replicates the DNS blocking configuration (adlists, whitelists, blacklists, groups, local DNS/CNAME records, and static DHCP assignments) between two Pi-hole 5.x instances. It was retired in July 2024 and does not support Pi-hole 6+.

Use cases

  • keep two pi-hole instances in sync
  • synchronize pi-hole adlists between primary and secondary
  • set up redundant pi-hole high availability
  • replicate pi-hole local dns records to a backup
  • automate pi-hole config replication with cron
  • sync pi-hole gravity.db between servers

When to choose

  • you run two Pi-hole 5.x instances and want them to share blocking configuration
  • you need a simple pull-based replication script with cron automation
  • you want community-maintained replication not offered by core Pi-hole

When to avoid

  • you run Pi-hole 6 or later, which changed the architecture
  • you need bidirectional merging or real-time replication
  • you want to sync query logs, statistics, or DHCP leases
  • you need actively maintained software
