The record

Purpose: Sniper is an open-source desktop web security proxy that intercepts, inspects, and modifies HTTP/HTTPS traffic for security testing, bug bounty work, and API debugging.
Intended users: The project names penetration testers, bug bounty hunters, security researchers, and developers as its intended users.
Traffic capture: It captures HTTP history and WebSocket sessions and provides an intercept queue and match-and-replace rules.
Testing tools: Features include request replay, payload-based fuzzing, and a passive scanner for sensitive data, CORS, missing headers, and JWT issues.
Automation: The bundled sniper-cli provides JSON-first scripting, and the repository includes Claude and Codex skill templates.
Proxy chaining: Sniper supports authenticated upstream HTTP and SOCKS5 proxy chaining; its incoming listener accepts HTTP proxy requests and CONNECT, not SOCKS client requests.
Security setup: The install instructions say each Windows installer has a SHA-256 file to check and that releases are not yet code-signed.
Remote access: A non-loopback headless UI listener requires authentication for remote clients, and the project warns that the UI serves HTTP rather than TLS.
Platform limitation: The README says Windows x64 is the first port and Linux validation is still pending.
License: The repository identifies Sniper as MIT licensed.
Downloads: The README directs Windows users to a setup executable or ZIP and macOS users to a DMG from GitHub Releases.
