Built for Privacy. Designed for Speed.

Every feature in Onyx exists because our red team knows exactly how browsers leak your data.

Built-in VPN

One-click VPN powered by OpenVPN. Your traffic is encrypted and routed through secure tunnels — no third-party extensions needed.

Ad & Tracker Blocking

Network-level blocking of ads, trackers, and fingerprinting scripts. No filter lists to manage — it just works.

Encrypted Password Vault

AES-256-GCM encrypted vault for your passwords and sensitive data. Your credentials never leave your machine unencrypted.

Advanced Tab Management

Tab groups, pinning, split-view, drag-to-detach, and mute. Manage dozens of tabs without the chaos.

10 Themes + Custom Accents

Dark mode by default, with 10 built-in themes, custom accent colors, and force-dark mode for any website.

Privacy Dashboard

See exactly what Onyx is blocking — trackers stopped, ads killed, and fingerprinting attempts defeated. Real-time visibility.

Encrypted Backup & Restore

Export your bookmarks, passwords, and settings as an encrypted .oxbk file. Restore on any machine.

HTTPS-Only Mode

Automatically upgrades connections to HTTPS. Sends Do Not Track and Global Privacy Control headers on every request.

Import from Chrome & Edge

One-click import of bookmarks, history, and saved passwords from your current browser. Switch without losing anything.

Built by Hackers.
For Everyone.

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.

Zero Telemetry

No data collection — period. We don't phone home.

Security patches ship fast. Updates install seamlessly.

Chromium Engine

Full web compatibility. Every site works as expected.
