A Nostr Profile Auditor
Paste an npub. One of our doctors will examine your Nostr identity across every relay you publish to, checking sync, verifying NIP-05, and scanning for Marmot Protocol compliance. You'll get a full diagnosis card with findings and a prescription.
- Discovers your relay list from kind 3 / 10002 / 10050 / 10051 events
- Detects out-of-sync profiles across relays
- Warns about single-relay fragility: one outage and you're unreachable
- Name, picture, about field completeness
- NIP-05 identity verification (live HTTP check against
.well-known/nostr.json) - Event freshness — how long since your last profile or contacts update
- Follow list size
- Inbox relay list (kind 10050) — giftwrap delivery for WhiteNoise messaging
- KeyPackage relay list (kind 10051)
- KeyPackage events (kind 443) with base64 encoding validation
- MLS protocol version and ciphersuite checks (0x0001–0x0007)
- Required extensions:
0xf2ee(marmot_group_data),0x000a(last_resort) - KeyPackageRef (i tag) hex integrity and length per ciphersuite
At the end, the doctor charts a diagnosis card: pass/warn/error counts, detailed findings, and a prescription for anything that needs fixing.
No build step. Zero npm dependencies. Just serve the static files — a local server is needed because the app uses ES modules and loads nostr-tools from a CDN.
# Python
python3 -m http.server 8000
# or Bun
bunx http-server
# or Node
npx http-server
# then open http://localhost:8000
Drop the files on any static host (GitHub Pages, Netlify, Vercel, Cloudflare Pages). No configuration needed.
- Paste an npub or sign in with a NIP-07 browser extension
- The doctor connects to bootstrap relays and discovers your relay list
- Every discovered relay is queried for your profile, contacts, and relay lists
- Your advertised KeyPackage relays are queried for KeyPackage events
- Sync analysis, profile validation, inbox relay checks, and MIP compliance checks run in sequence
- The doctor charts a diagnosis with findings and a prescription
