Deepseek Web Bridge

DeepSeek Web Bridge

**English** | [简体中文](README.zh-CN.md)

Turn an authenticated DeepSeek web session into a localhost-only, OpenAI-compatible API with a native macOS manager, a web dashboard, and Agent tool-calling support.

[!IMPORTANT] This is an unofficial local web bridge and is not affiliated with or endorsed by DeepSeek. Names such as `deepseek-v4-pro-web` are local aliases that map to modes visible in the web UI; they are not official API model identifiers or service guarantees.

Features

• Native macOS app — launch directly into a Chinese management dashboard
• Local API — listens on http://127.0.0.1:8741 by default
• OpenAI-compatible endpoints — Chat Completions, Responses, and Models
• Web mode selection — local aliases for Fast, Expert, and V4 Pro web modes
• Agent tool calls — converts structured tool requests from web responses into OpenAI tool_calls
• Claude Code Router support — works as an OpenAI-compatible CCR provider
• Automatic startup — registers a per-user LaunchAgent on first launch
• Built-in extension guide — complete Chrome extension setup instructions in the app
• Local-first storage — API configuration and logs stay on the Mac
