The Big Three

Native Rust + Slint

"Your frames belong to your game, not your chat app."

  • Zero Chromium. Compiled for the metal.
  • Tiny footprint. A fraction of the RAM of Electron apps.
  • Instant UI. Slint responds before you blink.

Tactical Audio

"Hear the Ghost Before the Peek."

  • SFrame E2EE. Voice encrypted at the source.
  • Elixir relay. Stateless forwarders, minimum hops.
  • Faster than standard WebRTC voice pipelines.

Quantum-Resistant E2EE

"Armor for the 22nd Century."

  • MLS Protocol. Ratchet-tree group encryption.
  • Hybrid ML-KEM-768. Post-quantum "harvest-now" defense.
  • Blind Server. Zero keys, zero knowledge.
