Every feature in Onyx exists because our red team knows exactly how browsers leak your data.
One-click VPN powered by OpenVPN. Your traffic is encrypted and routed through secure tunnels — no third-party extensions needed.
Network-level blocking of ads, trackers, and fingerprinting scripts. No filter lists to manage — it just works.
AES-256-GCM encrypted vault for your passwords and sensitive data. Your credentials never leave your machine unencrypted.
Tab groups, pinning, split-view, drag-to-detach, and mute. Manage dozens of tabs without the chaos.
Dark mode by default, with 10 built-in themes, custom accent colors, and force-dark mode for any website.
See exactly what Onyx is blocking — trackers stopped, ads killed, and fingerprinting attempts defeated. Real-time visibility.
Export your bookmarks, passwords, and settings as an encrypted .oxbk file. Restore on any machine.
Automatically upgrades connections to HTTPS. Sends Do Not Track and Global Privacy Control headers on every request.
One-click import of bookmarks, history, and saved passwords from your current browser. Switch without losing anything.
Blackbox Intelligence Group conducts penetration tests and red team operations for a living. We see how browsers leak data, how trackers follow you, and how your credentials get stolen.
Onyx Browser is the result of that knowledge — a browser where security isn't an afterthought. It's the architecture.
