Focused on what matters

Everything you need to keep your Ethereum validators healthy, nothing you do not.

Real‑time validator stats

Connect to Beaconcha.in for live balance, status, proposals and attestations, presented in a compact, operator‑friendly layout.

Health scores and alerts

See a single health score per validator based on effectiveness and balance growth. Get notified when something degrades, before it becomes a problem.

Multiple validators, one view

Track several Ethereum validators side by side, with a quick read on health, balance and performance for each.

Smart notifications, tuned for validator operators.

ETH Validator Monitor watches your validators and surfaces only the events that matter: health drops, offline validators, rising miss rates or new block proposals.

Health score

Set a custom health threshold and get pinged as soon as a validator drops below it.

Offline & miss rate

Catch multiple missed attestations or a high miss rate early, before rewards are hit.

Background mode

Minimizes to the tray and uses desktop notifications to pull you back only when needed.

Watch‑only by design.

ETH Validator Monitor never asks for private keys, keystores or seed phrases. You add validator indices or public keys only. Monitoring, not custody.

No private keys

Operate safely. All tracking is based on public validator indices only.

Read‑only data

We pull data from Beaconcha.in and never touch your withdrawal setup.

Keep keys offline

Cold storage stays cold. This tool is for visibility, not custody.

Open source. Free to use.
