💻 PC End-to-End Network Proxy Tools Explained in Plain English

“Commercial accelerators like LetsVPN” vs “v2rayN / FlClash and other open-source clients” explained thoroughly

💡 Core Difference in One Sentence

LetsVPN-type software: Equivalent to “a full-service taxi”, buying the software comes with a driver and route built in; launch it and you're good to go, but you can't modify or swap routes.
v2rayN / FlClash： Equivalent to “Premium Racing / Video Player”, the software itself is free (without routes), and needs to be used with "airport/node subscription (fuel)" to run, with powerful performance and high degree of freedom.

📊 Core Dimension Comparison Overview

Comparison Items	Commercial accelerators like Kuailian /VPN	Open-source clients such as v2rayN / FlClash
Product Nature	All-in-One Business Software (Built-in Nodes)	Open-source free tools (requires importing airport subscription/nodes)
Learning curve	★☆☆☆☆ (Extremely Easy) One-click on/off, register and pay to use	★★★☆☆ (requires study) Requires understanding of “ subscription import ”, “ routing ” concepts
Import External Nodes	❌ is completely unsupported Cannot use nodes such as VLESS and /Hysteria2	Supports all mainstream protocols VLESS, Hysteria2, VMess, SS, and more
Split Tunneling and Rules	Simple mode (global/smart), often accidentally blocks domestic websites	Ultimate Traffic Splitting Direct connection for domestic sites, proxy for overseas, specific sites routed to designated IP
Cost Performance & Value	Relatively expensive (tens of yuan per month, high unit price)	Software is free, nodes purchased separately

⚠ Key Point Explained: Why Can't QuickConnect-style Apps Import VLESS / Hysteria2 Airport Nodes?

Many beginners purchase “ airport nodes (including VLESS / Hysteria2 / VMess links) ”, and want to paste them into QuickConnect for use, only to find no import entry point anywhere. This is because there are fundamental conflicts in their underlying design:

1. Commercial closed-loop software doesn't open external entry points:
QuickConnect is a “ all-in-one commercial software ”, profiting from selling its own exclusive plans. To maintain a commercial closed loop, the vendor deliberately provides no “ third-party node import ” function button.

2. The underlying layer lacks code to parse open-source protocols (different kernel):
To parse VLESS, Hysteria2, TUIC and other popular protocols, the software must integrate Xray or Sing-Box / Mihomo open-source kernels. QuickConnect uses the vendor's self-developed closed proprietary encrypted tunnel, with no code written to unpack external open-source protocols; forcing a paste will simply result in “ cannot read ”。

3. Similar to the relationship between “ optical discs ” and “ players ”:
Airport subscription links are like a “ movie disc ”, you need to find a player that supports this disc format “ dedicated player (v2rayN / FlClash) ” to play it, while QuickConnect is a fixed cartridge player with a dead lock.

💡 Pitfall Avoidance Rule: If you have subscription links / node links / airport addresses / VLESS nodes in hand, please absolutely do not download QuickConnect, WaiYou, Jiguang and other commercial software! You must use the second category of open-source clients below.
