SenPaiScanner is a production-grade Cloudflare IP scanner with three frontends—a Bubble Tea TUI, a Wails v2 desktop GUI, and an Android Kotlin/Compose app—all sharing a common Go core. It scans Cloudflare's IPv4 ranges to discover reachable endpoints for VLESS/Trojan/VMess proxy configurations on filtered or high-latency networks. Scans run in two phases: a fast TCP/TLS/HTTP connectivity sweep, followed by optional validation through an embedded xray-core instance that measures latency, loss, jitter, and throughput. Results can be exported as raw endpoints, rewritten share URLs, Base64 subscriptions, Sing-box JSON, and Clash YAML, with live file output during scanning.
