Pax Connect for Mac · App interface is in Chinese
Claude Code · Mac
Pax Connect is a sing-box based Mac proxy client: Claude Code goes through the proxy without environment variables, relay API settings are managed in the app, and token usage and cost are tracked locally. The app interface is in Chinese.
Built on sing-box
TUN takeover, no environment variables

Pax does not replace Claude Code. It manages three things around it: how the network is routed, where the API points, and where usage goes.
01 · Proxy
Pax takes over traffic at the system level with TUN, so Claude Code needs no HTTPS_PROXY variable and no settings.json change. Switch between TUN and the system proxy when needed, and adjust routes and rules in the app.
A working network only shows the network is reachable. Whether Claude Code can sign in or make calls depends on your account and service.

02 · Relay
An API Profile stores a service address and key. Applying it to Claude Code writes ANTHROPIC_BASE_URL and the key into the env block of ~/.claude/settings.json. Any address of your own is accepted.
Saving and applying are separate steps: a profile marked as not applied has not switched Claude Code yet, and a successful write does not mean a model call will succeed.

03 · Usage
Pax reads Claude Code logs on your Mac and totals tokens, cache and cost by date, model and session, with the main session and subagents shown separately, so the most expensive session stands out.
Cost is estimated from a local price table. It is an API-equivalent amount, not a bill, and Pax does not show subscription quotas or limits.

Versus manual setup
Environment variables and config files work. Pax moves the repetitive, error-prone parts into an interface.
| Task | Manual setup | With Pax Connect |
|---|---|---|
| Proxying | Set HTTPS_PROXY in every terminal, or put it in the env block of ~/.claude/settings.json; edit again when the route changes. | TUN takes over at the system level with no variables; routes and rules switch in the app. |
| Checking the path | Test and guess whether traffic went through the proxy. | Traffic monitoring shows the actual route and matched rule per application. |
| Relay API | Edit ANTHROPIC_BASE_URL and the key by hand; keep several setups by copy-paste. | Profiles store several setups, write them to env on apply, and mark the unapplied ones. |
| Usage | Dig through logs or find a script. | Logs read locally and totaled as tokens, cache and estimated cost by date, model and session. |
Limits
These limits come first, so you do not find them after installing.
The routing rule interface can only select .app applications, not command-line programs such as claude. To send Claude Code through a specific route on its own, use a domain rule. With TUN takeover, claude process traffic is still recognized in traffic monitoring.
Pax does not supply nodes, subscriptions or relay services, and it does not recommend any relay provider. You bring your own routes and API service.
A successful proxy connection only shows the network is reachable. Whether Claude Code can sign in or make calls depends on your account and service.
Cost is an API-equivalent amount from a local price table, not a bill. Subscription quotas, limits and reset times are not shown.
Pax imports vless, vmess, trojan, hysteria2, anytls and ss links and Base64 subscriptions. It cannot import Clash YAML or sing-box JSON.
Requires a Mac with macOS 26 or later on Apple Silicon. The app interface is in Chinese only.
FAQ
The generic way is to set the HTTPS_PROXY environment variable in the terminal, or put it in the env block of ~/.claude/settings.json. With Pax TUN takeover turned on, Claude Code needs neither. See the Claude Code proxy setup guide for the steps.
Not directly. Rules can only select .app applications, not command-line programs. A domain rule gives a similar result, and claude process traffic can still be recognized and inspected in traffic monitoring.
Enter your own service address and key in a Pax Profile, then apply it to Claude Code. Pax writes to ~/.claude/settings.json. Saving and applying are separate steps, and Pax does not provide a relay service.
Pax reads Claude Code logs on your Mac and shows tokens, cache and estimated cost by date, model and session, with subagents counted separately. Cost is an API-equivalent estimate, not a bill.
No. Usage comes from local logs, so it does not depend on the proxy being on or on a saved profile.
