Lightning Network Map Screensaver
The Lightning Network Map screensaver dashboards the Bitcoin Lightning Network's real node count, channel count and total capacity, drawn key-less and live from mempool.space. It's free, runs in your browser, and ESC exits.
How the Lightning Network Map screensaver works
The saver fetches real current Lightning Network statistics from mempool.space, with no key required.
Node count, channel count and total network capacity are shown as large live readouts.
A field of glowing points suggests the real, growing mesh of Lightning nodes.
Readings refresh on a schedule to track real network growth.
A worked example
You'll see capacity measured in real bitcoin locked into payment channels — a genuine, if partial, measure of the public Lightning Network's size (some capacity is private and unlisted).
Settings & tips
- Accent recolours the glowing node field.
- Public statistics undercount private channels — the real network is somewhat larger.
- Capacity can be shown in BTC or sats depending on your preference.
