REALITY SNI candidate tester
Compare REALITY SNI candidates online
Use one endpoint and a short list of SNI names to see which handshakes produce clean TLS metadata, h2 ALPN and valid certificates.
The checker is intentionally rate-limited and does not perform CIDR scans; it is designed for manual auditing of known public targets.
✓
The tool runs directly in the browser and is ready for quick checks without installing software.
✓
Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
✓
Use fullscreen mode when you need more space for long text, structured data or large result blocks.
✓
Copy buttons are available on generated output so results can be reused in code, documents or support chats.
✓
Most operations are deterministic: the same input and options produce the same output.
✓
For sensitive content, prefer local browser tools and review the result before sharing it further.
