## What it is
Mars is a cross-platform network and infrastructure component library developed by Tencent's WeChat team, comprising STN (signaling/networking), Xlog (high-performance logging), SDT (network diagnostics), and comm (sockets, threads, coroutines). It is battle-tested by billions of WeChat users and optimized for mobile power and traffic efficiency.

## Use cases
- reliable logging in mobile apps
- cross-platform networking for Android and iOS
- small data transmission over weak mobile networks
- network quality diagnostics
- high-performance log component for C++ apps
- shared network layer across multiple platforms

## When to choose
- building a multi-platform mobile app needing one shared C++ network stack
- you need efficient, crash-safe logging on mobile
- your app must handle weak or unstable mobile networks with low power usage

## When to avoid
- you need a full-featured HTTP client with modern web APIs
- your project is server-side or desktop-only with no mobile targets
- you want a pure high-level managed-language solution without C++ integration

## Facets
- artifact type: library
