Why CryFox

Privacy without compromise.

Purpose-built controls, fast rendering, and a zero-leak policy so your work stays confidential.

Zero telemetry

No remote experiments, analytics, or surprise pings. What runs on your machine is the code you installed.

Fingerprint defense

Protects against canvas, audio, font, and hardware fingerprinting out of the box.

Isolated workspaces

Split workspaces, personas, and tab groups into fully isolated sandboxes.

Oblivious DNS routing

Encrypted, anonymized DNS routing to keep lookups unlinked from you.

Security

Built for people who take security seriously.

Every workspace is isolated, extension access is scoped, and updates are signed and verified.

  • Per-room storage keys and cookie boundaries.
  • Signed update chain with rollback protection.
  • Policy packs for team-wide configuration.
  • Site permissions that expire automatically.

  • Smart cache warming with privacy-aware prefetching.
  • Tab hibernation for idle sessions.
  • GPU-first rendering across modern hardware.
  • Private tabs without slowing your session down.
