BridgeHop

A lightweight, cross-platform Tor bridge reachability scanner with a modern UI.

BridgeHop tests whether Tor bridges are reachable from your network across all bridge types — vanilla, obfs4, webtunnel, snowflake, meek, conjure, and dnstt — so you can quickly find bridges that actually work where you are. It ships with built-in bridge lists and live sources, and you can add your own.

Built with Tauri (a small Rust core + web UI) and a matching command-line companion that shares the same engine.

Features: • Reachability checks for every transport – Fast TCP-connect probe for direct transports (vanilla, obfs4, …). – Front-host TLS probe on :443 for fronted/broker transports (snowflake, meek, conjure, dnstt, webtunnel) — a completed TLS handshake confirms fronting works. • Built-in lists & live sources — the community bridge collector (with mirror fallback), built-in defaults for fronted transports, and your own bridges (pasted or imported from a file). Fetched lists are cached and served (stale) when you're offline. • Deep verify (desktop) — optionally launch the real obfs4 client (lyrebird/obfs4proxy) to confirm an actual handshake; prompts you to install it if it's missing. • Scan history & reliability — every scan is recorded; the Library ranks bridges by uptime and latency across runs. • Import / export — plain lines, torrc, JSON files, and per-bridge QR codes for sharing. • CLI companion — scriptable scanning and exporting that shares the app's engine and database. • 8 languages — English, German, French, Russian, Simplified Chinese, South Azerbaijani, Central Kurdish, and Persian (right-to-left supported). • Modern, responsive UI — light/dark theming, live result streaming, and a mobile layout.
