190X4 · SECURE TUNNEL
A Windows desktop networking client built around sing-box, WARP, routing rules and connection diagnostics.
Not an anonymity guarantee. Ninety gives you careful connection control, Windows mode handling and visible diagnostics.
Windows networking client
Ninety brings subscriptions, standalone profiles, WARP, TUN, routing, logs and auto-updates into one desktop client. The project focuses on predictable connection state, honest limitations and careful Windows network handling.
Features
Local proxy, system proxy, VPN · TUN and WARP-only. Elevated mode is used only when the selected mode actually needs it.
Subscriptions, standalone links, TrustTunnel endpoint files and WireGuard/AmneziaWG .conf files. Clipboard import and deep links stay in one user flow.
LAN bypass, regional rules, custom domain/IP/process rules and a separate live connections monitor.
Delay checks, throughput watching, node re-tests, recovery hints and useful logs instead of a vague connected label.
sing-box remains the central router, while XHTTP, NaiveProxy and TrustTunnel are attached through local bridges when a profile requires them.
Tray control, post-update session restore, themes, onboarding, localizations and cautious defaults for logs and runtime configs.
Interface
Documentation
The docs explain modes, privacy, routing and troubleshooting without asking users to publish private URLs, UUIDs, keys, WARP state or full configs.
Releases are published through annotated tags, draft releases and CI assets. The OTA changelog comes from latest.json, not from an already published release body.
Safety notes
Privacy depends on the server, provider, profile and Windows environment. Ninety helps manage the connection, but it does not change that trust model.
Public issues must not include subscription URLs, UUIDs, tokens, private keys, WARP data or full exported configs.
TUN, kill switch and DPI compatibility can change Windows networking state. Enable them deliberately and check settings before reporting bugs.
