By default, all features are enabled. Single features can be disabled in the config.

Setup of initial instances

New AdGuardHome replica instances can be automatically installed if enabled via the config autoSetup. During automatic installation, the admin interface will be listening on port 3000 in runtime.

To skip automatic setup

Install

Get from releases or install from source

go install github.com/bakito/adguardhome-sync@latest

Prerequisites

Both the origin instance must be initially setup via the AdguardHome installation wizard.

Username / Password vs. Cookie

Some instances of AdGuard Home do not support basic authentication. For instance, many routers with built-in Adguard Home support do not. If this is the case, a valid cookie may be provided instead. If the router protects the AdGuard instance behind its own authentication, the cookie from an authenticated request may allow the sync to succeed.

This has been tested successfully against GL.Inet routers with AdGuard Home.
Note: due to the short validity of cookies, this approach is likely only suitable for one-time syncs

Run Linux/Mac

export LOG_LEVEL=info
export ORIGIN_URL=https://192.168.1.2:3000
export ORIGIN_USERNAME=username
export ORIGIN_PASSWORD=password
# export ORIGIN_COOKIE=Origin-Cookie-Name=CCCOOOKKKIIIEEE
export REPLICA1_URL=http://192.168.1.3
export REPLICA1_USERNAME=username
export REPLICA1_PASSWORD=password
# export REPLICA_COOKIE=Replica-Cookie-Name=CCCOOOKKKIIIEEE

# run once
adguardhome-sync run

# run as daemon
adguardhome-sync run --cron "0 */2 * * *"

Run as Linux Service via Systemd

Verified on Ubuntu Linux 24.04

Assume you have downloaded the the adguardhome-sync binary to /opt/adguardhome-sync.

Create systemd service file /opt/adguardhome-sync/adguardhome-sync.service:

[Unit]
Description = AdGuardHome Sync
After = network.target

[Service]
ExecStart = /opt/adguardhome-sync/adguardhome-sync --config /opt/adguardhome-sync/adguardhome-sync.yaml run

[Install]
WantedBy = multi-user.target

Create a configuration file /opt/adguardhome-sync/adguardhome-sync.yaml, please follow Config file section below for details.

Install and enable service:

sudo cp /opt/adguardhome-sync/adguardhome-sync.service /etc/systemd/system/

sudo systemctl enable adguardhome-sync.service

sudo systemctl start adguardhome-sync.service

Then you can check the status:

sudo systemctl status adguardhome-sync.service

If web UI has been enabled in configuration (default port is 8080), can also check the status via http://<server-IP>:8080
