About Sniper
Sniper is a native desktop web security proxy built in Rust that intercepts, inspects, and modifies HTTP/HTTPS traffic. Designed for penetration testers and security researchers, it provides a modern alternative to heavy proxy platforms for tasks like bug bounty hunting and API debugging. The tool features a native desktop application with an embedded web UI, a JSON-first CLI (`sniper-cli`) for automation, and built-in support for AI agents. Key capabilities include: - **Traffic Management:** HTTP forwarding, HTTPS MITM, and authenticated proxy chaining (HTTP/SOCKS5). - **Automated Testing:** A passive vulnerability scanner for detecting sensitive data leaks, CORS misconfigurations, and JWT issues, alongside a payload-based fuzzer. - **Browser Integration:** One-click launching of pre-configured browsers (Chrome, Edge, Brave, ego, Aside, BrowserOS neo) that are automatically wired to the proxy and root CA. - **AI Readiness:** Includes skill templates for Claude and Codex, allowing AI agents to drive browsers and interact with captured traffic via the CLI. - **Analysis Tools:** A service map for visualizing captured origins and APIs, WebSocket session inspection, and tools for decoding, hashing, and JWT inspection. Sniper supports macOS, Windows (x64), and Linux (specifically Debian 13 x86_64 on X11). It operates as a single Rust binary with no external runtime requirements.
