Neynar Explorer helps developers debug event propagation1 on the Farcaster network.

​
Start exploring

You can use the search bar to explore the network
  • Node and API tabs will show where an event has propagated after clicking on the “Network response” button. Nodes / APIs that are missing events will be highlighted in red ❗️ , partially missing data will be highlighted in yellow ⚠️ and fully synced will be green ✅ Screenshot2025 05 14at6 52 48PM Pn
  • Clicking on a tab opens more details, allowing you to compare objects across nodes and APIs. Screenshot2025 05 14at6 47 08PM Pn

Things you can explore

  • Specific casts: e.g. 0x1a37442d0bd166806b6bc3a780bdb51f94d96fad (cast hash) or https://warpcast.com/v/0xf809724b
  • Specific users: e.g. 194 (user’s fid)
  • Cast search with keywords: e.g. $higher
    • this will also show metrics of how often that keyword has appeared on the network recently
    • results can be filtered by username (cast author), channel_id (channel of cast)
    • results can be sorted by desc_chron or algorithmic
    • search mode can be changed between literal, semantic or hybrid
    • read more about our cast search API, tap “Network response” to see event propagation for any cast
  • User search with usernames: e.g. rish
    • read more about our user search API, tap “Network response” to see event propagation for any user
  • Follow relationships: e.g. 194<>191 to see relationship between two FIDs
  • Feed API results: e.g. https://api.neynar.com/v2/farcaster/feed/trending?limit=10&time_window=24h&provider=neynar
    • put any Feed API url from Neynar docs and evaluate results in a feed like format before you build a feed client
    • see our Feed APIs

What else do you want to explore?

Hit us up with feature requests, we want to make debugging as easy as possible for developers! 1 Read more on event propagation in Understanding Message Propagation on Farcaster Mainnet. The blog was written at the time of hubs but similar debugging for snapchain syncs apply.
