LNvis

A Lightning Network Visualizer

Usage

LNvis requires a json dump of nodes and channels. Currently only clightning channel/node output is supported

lightning-cli listnodes > clightning-nodes.json && \
lightning-cli listchannels > clightning-channels.json && \
./lnvis --channels clightning-channels.json \
        --nodes clightning-nodes.json

Controls

b             view multiple channels between nodes
t             toggle dark/light theme
f             toggle fps
a             toggle aliases
g             toggle grid
s             toggle stroked nodes (small perf boost)
left click    move + focus node
right click   filter node

How it works

LNvis renders the Lightning Network channel gossip, which include nodes and the edges (channels) between those nodes.

• Channels are colored by the node that opened the channel

• Channel widths are rendered proportional to the capacity

• Right clicking a node filters the view to that node and its neighbors

• Dragging a node in any view will focus that node and its neihbors
