About nostrmap.com

nostrmap.com is a world map of the public Nostr relay network. It shows every relay we can find, where its server is located, whether it is online, how fast it responds, which software it runs, and which NIPs it supports.

How the data is collected

Our crawler checks relays continuously (a cycle every couple of minutes; each relay is revisited roughly every 15 minutes, unreachable ones hourly) and, for each known relay:

• requests the relay's NIP-11 information document over HTTPS,
• opens one WebSocket connection, sends a single request for one event, waits briefly for a response, and closes the connection cleanly (never more than one connection at a time to the same server),
• resolves the server's approximate location from its IP address using the DB-IP City Lite database (rounded to about 1 km before it is published; relays that share the same rounded city position are drawn on a small circle around it, so every relay stays visible and clickable).

Relays are discovered from a public seed list and from NIP-65 relay lists (kind 10002) that users publish on the network. All data shown on this site is available as open JSON: see relays.json, stats.json and stats-history.json, or as a spreadsheet-friendly table: relays.csv. Every relay has a permalink page (/relay/<id>/) with an embeddable status badge (/badge/<id>.svg) for operator READMEs.

Opt out

Relay operators can exclude their relay from nostrmap by adding this to their NIP-11 document:

"nostrmap": { "exclude": true }

The relay is removed from this site within one crawl cycle. You can also contact us (see below) to be excluded manually.
