LinkQuota
Netlify Edge relay with a VPS-side VLESS subscription manager for routing traffic through a Netlify domain while managing per-customer accounts, subscription links, quota, expiry, and enable/disable state.
LinkQuota is a small, auditable stack for operators who manage per-customer VLESS accounts on their own infrastructure. It pairs a Netlify Edge relay with a VPS-side manager that handles subscriptions, quota, expiry, and account state.
