FAQ
What is the difference between a VPN, a proxy, and an “airport”?+
A VPN app like UmiVPN connects in one tap. A proxy client like VX imports your own nodes or subscription. An airport sells those nodes. NUNU is a free mobile accelerator. vx-core is the open-source engine underneath VX and UmiVPN.
Which product is a free VPN?+
UmiVPN includes a free plan on all major platforms (3 GB/month, with common AI sites unmetered). NUNU is permanently free with unlimited traffic on phones. VX is free and open source, but you bring your own nodes.
Desktop or phone?+
Need one-tap VPN on computer and phone: UmiVPN. Phone only and want it free forever: NUNU. You already have a subscription or VPS: VX. You only need nodes: Konglong Airport.
