OnionHop

V3 is a ground-up rebuild on a new cross-platform UI stack, with a much smarter connection engine and a far wider set of censorship-resistant transports.

Now cross-platform — native desktop builds for Windows, macOS (signed & notarized universal app) and Linux (AppImage). Same app, native look on each OS. Redesigned UI — Fluent/native look (FluentAvalonia), light/dark/follow-system themes, an accent picker, an integrated chromeless title bar on Windows and native window chrome on macOS, and 5 languages (English, German, French, Chinese, Russian). Smart Connect — an offline censorship "brain" that auto-picks the best connection strategy for your network and country: it knows where Tor is blocked, prefers transports that survive there, pre-tests bridge reachability, races strategies in parallel, fails fast off dead paths, and remembers what worked on each network so the next connect is instant. Three Tor engines — Classic (tor.exe, full control: bridges, country/entry/exit pinning, control-port New Identity), Arti (the Rust Tor implementation), and ArtiHop (shortened 2-hop Guard?Exit circuits for lower latency, with live New Identity). More censorship-resistant transports — obfs4, snowflake (with optional AMP-cache fronting), webtunnel, conjure, meek, and dnstt (a DNS tunnel that gets Tor through when only DNS is allowed). Bridge Scanner — fetch and reachability-test bridges of every transport, see color-coded latency, and one-click apply the ones that actually work on your network. More bridge sources — the official Tor bridge service, the censorship-resistant OnionHop Bridges Collector (derived from Delta-Kronecker/Tor-Bridges-Collector), built-in community bridges, and a thin-set top-up so a tiny live fetch is automatically backed by bundled bridges. Relays browser — search the live Tor relay list by nickname, country, role, flags and bandwidth, and pin a preferred entry/middle/exit. Command-line interface — a full-featured TUI (OnionHopV3.Cli) with a live status dashboard, connect/scan/bridges/snowflake/relays commands and settings persistence. (Windows now; Linux & macOS CLI coming soon.) Stronger leak protection — optional full DNS-over-Tor, a kill switch, UDP blocking in TUN mode, and an in-app WebRTC/UDP privacy notice. Volunteer as a Snowflake proxy — help censored users reach Tor, straight from Settings. Quality-of-life — decoupled system-proxy toggle (turn it off while Tor stays connected), an opt-in persistent admin helper to skip repeat UAC prompts in TUN mode (off by default), an in-app changelog, and Bitcoin donations.
