How does Claude Code use a proxy?

Pax Connect uses TUN interception to route Claude Code traffic through proxies without requiring HTTPS_PROXY environment variables or manual configuration file edits. The app automatically manages proxy settings and shows which proxy route each connection uses.

Does Pax Connect provide proxy nodes or relay services?

No. Pax Connect does not provide proxy lines, relay services, or AI account access. Users must prepare their own proxy lines, relay APIs, and AI service accounts. The app only manages and routes traffic through services the user supplies.

Is the cost estimate in Pax the same as my API bill?

No. The cost shown in Pax is an estimate based on local price tables and API-equivalent calculation, not an actual account bill. Official subscription quotas and limits are not displayed in Pax.

When should I start a new session?

Start a new session when context length enters the limit zone for your model. Pax displays safety, warning, and limit zones for each model (GPT 272k limit, Claude Opus 200k limit, Sonnet 250k limit). Exceeding the limit means every request resends very long context, costing more and responding slower. Bringing key points to a new session uses your token budget more efficiently.

Can Pax import Clash subscriptions?

Pax can import Base64 subscriptions and node links, but cannot import Clash YAML or sing-box JSON formats. See the import documentation for supported protocols.

Overview

Screenshot of the Pax Connect homepage — What paxconnect.top looks like

Pax Connect is a native Mac application that provides proxy management for Claude Code and Codex developers. Built on the sing-box network kernel, it enables TUN interception to route traffic through proxies without requiring environment variables, manages multiple API configuration profiles that can be switched with one click, and reads local logs to track token usage and estimate costs for different models and sessions.

The app supports multiple proxy protocols including VLESS, VMess, Trojan, Hysteria2, AnyTLS, Shadowsocks and Base64 subscriptions. It provides detailed session analysis showing context length, cache usage, and cost trends, with warnings when context reaches model limits. Users can monitor costs per model, per tool (Claude Code, Codex, or DeepSeek Harness), and per session, with separate tracking for main sessions and sub-agents.

Pax Connect does not provide proxy lines, API services, or AI accounts—users must supply their own. The app interface is currently available only in Chinese, and requires macOS 26 or later with Apple Silicon. It is offered as a free beta version that is not officially signed or notarized by Apple.
