Nagis is the serpent’s shield — a quiet control plane for stealth tunnels you actually own.
Coil. Shield.
Threshold.
From naga (serpent) and aegis (divine shield): a guardian at the threshold — not a toy VPN brand.
One plane.
Many thresholds.
Endpoint = the listener. Access = a person’s credential and client link. Quota = how many MB/GB they may transfer across all their Accesses before the VPN stops (non-bootstrap credentials leave the engine). Import a subscription URL in v2rayN / v2rayNG to see used / total.
Shared Reality / XHTTP / Hy2 listeners — infrastructure, not “Alice’s tunnel.”
Per-user credential + link/QR on an Endpoint. This is what phones import.
Cumulative MB/GB per User across Accesses. Over limit → Access cut until reset.
