Test relay connectivity, speed, and NIP support
Enter a relay URL to test connectivity and performance

Popular Relays:
Comprehensive relay analysis
Verifies that the relay accepts WebSocket connections and responds to protocol messages.
Measures connection time and round-trip latency to assess relay performance.
Tests read and write permissions to determine what operations are allowed.
Checks which Nostr Implementation Possibilities (NIPs) the relay supports.
Retrieves relay metadata including name, description, software, and contact info.
Tests the relay's ability to respond to event subscription requests.
Understanding Nostr Implementation Possibilities
Core Nostr protocol - events, filters, and relay communication.
Following list and relay recommendations.
Encrypted direct messages between users.
DNS-based identity verification.
Request deletion of previously published events.
Relay metadata and capabilities document.
Event expiration timestamps.
Client authentication to relays.
A Nostr relay is a server that stores and forwards Nostr events. Relays are the backbone of the Nostr network, allowing clients to publish and subscribe to events.
Testing helps you find reliable, fast relays with the features you need. It also helps relay operators identify and fix issues.
Connection time is how long it takes to establish a WebSocket connection. Round-trip time (ping) measures response latency. Lower numbers are better.
NIPs (Nostr Implementation Possibilities) are standards that define how different features work in Nostr. Relays implement different NIPs based on their capabilities.
Under 500ms is excellent, 500-1000ms is good, 1000-2000ms is acceptable, over 2000ms may cause delays.
Read permission allows you to retrieve events. Write permission allows you to publish events. Some relays are read-only or require authentication.
