MoneroWatch

A live Monero network display that runs entirely in the browser. No backend, no trackers, no third-party scripts.

Open MoneroWatch → — or clone it and run it yourself (see Run).

What it shows

• Block height, estimated network hashrate, block reward (tail emission), and tx pool size
• XMR price in USD, piconero per dollar, and the XMR/BTC ratio

Features

• Add, remove, and configure displays; a display can rotate through several stats
• Fullscreen mode per display
• Installable PWA: opens offline and shows last-known values
• Custom monerod node URL in settings. Public nodes see your IP; your own node does not.
• Polls chain data every 10 seconds and price every 30 seconds; pauses when the tab is hidden

Run

python3 -m http.server 8000

Open http://localhost:8000. Opening index.html directly also works, but PWA install needs http(s).

Data sources

• Chain: monerod JSON-RPC (get_info, get_last_block_header). Default node is xmr-node.cakewallet.com:18081; change it in settings.
• Price: Kraken public API, with CoinGecko and Bitfinex as fallbacks. Every request is time-boxed to 8 seconds.

Pointing at your own node

monerod rejects browser requests unless you allow this page's origin:

monerod --rpc-bind-ip 0.0.0.0 --confirm-external-bind \
        --rpc-access-control-origins 'http://localhost:8000'

Then set the node URL in settings, e.g. http://192.168.1.10:18081.

Two browser rules to know:

• A plain-http node needs a plain-http page. Browsers block http requests from an https page (mixed content), so a node at http://192.168.1.10:18081 or http://127.0.0.1:18081 will not work on the hosted version — the request fails silently and the widgets just stop updating. Run MoneroWatch locally for that, or give your node a TLS certificate and use an https URL. The default public node is https, so the hosted version works out of the box.
• The origin must match exactly in --rpc-access-control-origins — scheme, host, and port. Use https://orangepane.github.io for the hosted version, http://localhost:8000 for a local one.

A note on the tx pool

Monero's transaction pool is public — that is what the tx pool widget reads. What Monero hides is amounts, senders, and receivers, not the existence of pending transactions.

The Monero symbol is from the getmonero.org press kit. Fonts are Red Hat Mono (SIL OFL 1.1).

Sister projects

• BitcoinWatch: the same display for bitcoin. Block height, price, sats per dollar, mempool, hashrate, halving countdown.
• btc-ticker: the same idea, simpler: a live BTC price in 6 currencies on one static page. Same rules: no backend, no trackers, nothing but the numbers.
