Noctis

Noctis

Route your Chromium browser’s traffic through proxy servers (VLESS, Shadowsocks, Trojan, and others) using a local helper powered by sing-box. The extension is the control panel; sing-box does the networking. No system VPN, no separate client window — everything stays inside the browser.

What you get

  • One or more proxy servers configured from share links, QR codes, or subscription URLs.
  • Per-rule routing: which sites use which server, which go direct, which are blocked.
  • Background health checks and automatic failover.
  • Popup, side panel, and full options page — pick whichever fits your screen.
  • No accounts, no telemetry, no remote calls (beyond traffic you explicitly proxy and subscription URLs you add).

Install

  1. Install the Noctis extension from the Chrome Web Store — link coming once the store listing is live.
  2. Install the native helper from the Install page.
  3. Open the extension, add a server, and route your traffic.

Why two parts?

Browsers cannot run a sing-box engine on their own. Noctis splits the work:

  • Extension (closed-source) — control panel + storage. Distributed via the Chrome Web Store.
  • Native helper (noctis-host, open-source) — Go binary that supervises sing-box on your machine. Source: https://github.com/Krasnopolskiy/noctis-host.

Nothing leaves your machine except the traffic you explicitly route and the subscription URLs you choose to add.
