TLS Analyzer & VLESS Reality Configuration Tool
Probe domains for TLS 1.3 · HTTP/2 ALPN · X25519 · CDN detection · Config generation
Reality Probe is a TLS analysis tool that finds optimal SNI domains for XTLS Reality protocol configuration. It probes domains for TLS 1.3 support, HTTP/2 ALPN negotiation, X25519 key exchange, and CDN characteristics — then generates ready-to-use configs for popular proxy platforms.
| Feature | Description |
|---|---|
| TLS 1.3 + H2 Detection | Probes ALPN negotiation — the key parameter for Reality camouflage |
| Multi-IP DNS Resolution | Detects CDN-backed domains (multiple A records) |
| Quality Scoring | Rates domains: IDEAL → GOOD → FAIR → POOR based on TLS profile |
| 120+ Built-in Domains | Works fully offline with a curated domain list |
| Multi-Source Discovery | Majestic Million, Cloudflare Radar, Certspotter, GitHub lists |
| Smart Filtering | Skips internal CDN infrastructure, staging domains, unsuitable targets |
| Config Generation | Ready configs for Xray, sing-box, Mihomo, NekoRay |
| X25519 Key Generation | Auto-generates private/public keys, UUID, short_ids |
| TCP Pre-check | Verifies port availability before TLS handshake |
| Web Dashboard | Clean web UI with real-time probing progress |
| Quick Probe | Check any domain instantly from the UI |
| CSV/ZIP Export | Export results for analysis |

The scoring system evaluates domains on multiple factors:
| Factor | Points | Why It Matters |
|---|---|---|
| TLS 1.3 | +30 | Required for Reality protocol |
| HTTP/2 (ALPN) | +25 | Legitimate H2 handshake profile |
| X25519 key exchange | +15 | Preferred key derivation for Reality |
| CDN-backed (multi-IP) | +10 | Higher reliability |
| Low RTT (<100ms) | +10 | Better performance |
| Valid certificate | +5 | Standard TLS behavior |
| Session tickets | +5 | Normal TLS extension |
Status labels:
- IDEAL (85+) — TLS 1.3 + H2 + X25519, perfect Reality target
- Excellent (70+) — Strong candidate
- Good (50+) — Usable
- Poor (<50) — Not recommended
Select a domain → click USE → get ready configs:
- Xray-core — inbound + outbound JSON
- sing-box — inbound + outbound JSON
- Mihomo (Clash.Meta) — YAML proxy config
- NekoRay — JSON config
- Share URI —

All configs include auto-generated X25519 keys, UUID, short_ids, and recommended flow settings.
