Which Nostr relays actually work?
Nostr clients read the relay list a user publishes (NIP-65, kind 10002) and connect to whatever is in it. This page takes those lists from people who actually posted recently, opens a WebSocket to every relay they name, and asks a single question: does anything come back? Measured 2026-08-07 04:12 UTC, re-run every day.

| Active posters sampled | 741 |
| …of them with a published relay list | 265 (36%) |
| Distinct relays those lists name | 579 |
| Reachable (answered anything) | 262 (45%) |
| Serving events on a plain query | 194 (34%) |
| Not reachable at all | 317 (55%) |
| Median handshake time | 502 ms (p90 834 ms) |
What came back, in detail
| Result | Relays | Share | Meaning |
|---|---|---|---|
| Serving events | 194 | 34% | Connected, answered the query, returned a note. |
| DNS failure | 117 | 20% | The name does not resolve. |
| HTTP error | 103 | 18% | The host answered, but not with a WebSocket upgrade (404, 410, 502, 530 …). |
| Timeout | 48 | 8% | No answer within the timeout. |
| Auth required | 45 | 8% | Answered with AUTH or closed the subscription asking for authentication (NIP-42). |
| TLS failure | 28 | 5% | Certificate expired, wrong host, or otherwise unverifiable. |
| Connected, no events | 19 | 3% | Connected and answered, but returned nothing for a generic query. |
| Other failure | 9 | 2% | Everything else; the raw error is in the dataset. |
| Connection refused / reset | 7 | 1% | Nothing is listening, or the connection was dropped. |
| Connected, silent | 5 | 1% | WebSocket opened, then nothing came back. |
| Rejected the query | 4 | 1% | Connected, then closed the subscription for another reason. |
Two columns matter when reading the tables below. Advertisers is how many distinct pubkeys name the relay. Distinct lists is how many different relay lists it appears in — a swarm of accounts publishing one identical list counts many times in the first column and once in the second. Bridges and test swarms are a real part of Nostr, so they are not filtered out; the second column is there so you can see them.

Advertised but not reachable
These are in people's published relay lists right now and answered nothing from this vantage point. If your client is slow to load a profile, this is one of the reasons: it is waiting on hosts like these.

Method
- Sample frame. Pull the most recent kind-1 notes from 6 seed relays and keep the distinct author pubkeys. That is "people who posted recently", not a directory.
- Relay lists. Query kind-10002 for those authors against several index relays, keeping the newest list per pubkey (kind 10002 is replaceable).
- Probe. Open a WebSocket to every advertised URL and send
REQ {"kinds":[1],"limit":1}. Classify by what actually comes back: an event, EOSE, AUTH, CLOSED, a NOTICE, or a transport error.
The whole thing is one Python file with one dependency, run by a scheduled GitHub Action from a public repository, committing its own raw output. Vantage point: GitHub Actions runner (ubuntu-latest).
What this does not show
- One vantage point. A relay unreachable from a GitHub runner may be fine elsewhere — geo-blocking, IP reputation and Tor-only relays all look like failure here.
- One moment. This is a snapshot, re-taken daily. A relay having a bad minute is indistinguishable from a relay that is gone. The daily series will separate the two over time; a single run cannot.
- Auth and payment are not failure. Relays that ask for NIP-42 auth or a subscription are working as designed and are counted separately.
- The frame is biased toward users whose notes reach the seed relays, and toward whoever posted in the minutes before the run.
