CTC is a subscription-link service, not a standalone app — you'll use it inside a client you already trust.
No installer, no native app — just an SS / SS-2022 subscription link and a client you probably already have.
Pick a tier on the pricing page — Starter, Cruise, or Dedicated Line — based on the monthly data and node priority you want.
After choosing a plan you receive a subscription link (订阅链接) containing your SS / SS-2022 node list, ready to import into a client app.
Paste the subscription link into any supported client below and connect — the client handles node selection and switching automatically.
CTC subscription links work with any client that supports Shadowsocks / SS-2022, including the full Clash family.

CTC deliberately doesn't ship its own client app. Dedicated proxy clients like Shadowrocket, Clash Meta, and sing-box are actively maintained, widely trusted, and already familiar to the exact audience CTC serves — anyone comparing airport recommendations (机场推荐) has usually run one of these clients before.
Using an existing, well-audited client also means you get rule-based routing, traffic statistics, and per-app proxying for free, while your CTC subscription link simply supplies the SS / SS-2022 node list underneath it.
This page is an informational guide to getting a CTC subscription set up — use the Get Started button to proceed to the current plan and setup options.
Shadowrocket is the most widely used option on iOS; Clash Meta is the equivalent on Android and desktop. Any client listed above works — pick whichever you're already comfortable with.
Tiers that include Emby access provide a separate Emby client login alongside your CTC subscription details — it's a bonus media library, not part of the proxy subscription link itself.
