I built Nostr Inspect https://nostrinspect.com for Nostr devs and curious people who want to see what's really on relays 👀

• Search or stream live from multiple relays at once
• Filter by kind, NIP, author, tags and time range
• Open any event by nevent / note / naddr and verify its signature, id and which relays have it, right in your browser
• See when a newer version of a replaceable event exists
• Share links to events or to full searches
• Not sure what to look for? Try a random query

Building a client or app? Add a "Verify on Nostr Inspect" link to your events.
