LIGHTNING ATLAS
A real-time, editorial dashboard for the Bitcoin Lightning Network. Free, open, no accounts, no tracking.
ln.fyi is an open dashboard for the Bitcoin Lightning Network — a real-time control-room view of every public node, channel and satoshi flowing through the network's second layer.
The Lightning Network is a payment protocol built on top of Bitcoin that enables instant, near-zero-fee transactions by opening state channels between participating nodes. Thousands of nodes run it quietly around the world. Most of the data is public, but it is not especially legible.
This site aims to fix that. It reads public data from mempool.space's Lightning API and renders it as a single, data-dense dashboard you can use to understand the state and trajectory of the network without clicking through pages, or installing anything, or signing up for anything.
It is intentionally minimal: one screen, real numbers, no ads, no tracking, no upsell. Every chart and table here is rebuildable from the same public endpoints — the code is open.
Primary live feed for all metrics on this site. A community-run mempool.space instance whose Lightning crawler is kept current — network-wide statistics, node rankings, geographic distribution, ISP breakdown and individual node histories.
The open-source explorer that defines the API schema we consume. The flagship mempool.space instance hosts the reference docs; we query an up-to-date mirror running the same software.
The underlying protocol. Layer-2 payment network built on Bitcoin, enabling instant, low-fee transactions through payment channels.
The dashboard — capacity, channel count, node count, fee rates, top liquidity leaders, routing hubs, country breakdown. Everything at a glance.
Every public Lightning node, ranked by liquidity, connectivity or age. Searchable; click any row for the node’s full profile.
Lightning capacity, nodes and top hubs for every country running the network. Click a country for its breakdown.
Where the network physically runs — every hosting provider, ranked by capacity, with the nodes they carry.
The code behind this site is open and publicly readable. Every API call, every transformation, every chart is in the repository. You can fork it, audit it, self-host it, or open an issue. Built with Next.js, TypeScript, and Tailwind.
