Endpoint Security + Network Extension entitlements.
Distribution-level access for kernel-grade macOS security.
A software studio,
engineered end to end.
Quantum Encoding is a founder-led engineering studio. We design and ship cross-platform applications, bespoke commerce platforms, and the systems-level tooling that powers them, from native macOS and iOS to Tauri on the desktop and the web.
The vision
The future of AI is local.
On your device. No token fees. Your data, and nobody else's.
The whole industry is betting trillions on multi-billion-dollar datacentres, then renting that intelligence back to you by the token. We build in the opposite direction: AI that runs on hardware you already own. Modern Apple silicon is the most efficient AI hardware on the planet; a single laptop can run a 120-billion-parameter model on under 140 watts. When compute is that capable and that close, the intelligence is genuinely yours: private by default, with no meter running.
Quantum Encoding Ltd is committed to building software for what comes next: tools made for AI to use, and for people to collaborate with.
In practice: Metatron Security and Cosmic Duck OS. Metatron is the containment layer for agentic AI, kernel-level governance that keeps autonomous agents inside hard boundaries. Cosmic Duck OS is the native client people use to run them, with on-device model routing and local tool execution on Apple silicon. The security system, and the runtime that puts it to work.
What we build
Cross-platform, down to the kernel.
We ship to every platform our users live on: native macOS and iOS in Swift, Android, Tauri on the desktop, and the web. Underneath the apps sits the part most studios outsource: the systems-level tooling, written in Rust, Go, and Zig, that does the heavy lifting our products depend on.
Some of that work needs access most teams never get. We hold restricted Apple entitlements (Endpoint Security and Network Extension), the kernel-grade permissions behind security software like Metatron. Apple grants them sparingly, and they let us build things that simply aren't possible from user space.
What we ship
Four flagship products.
Independent brands, all running on infrastructure that reflects our local-first thesis.
Flagship
Metatron Security
Kernel-level macOS governance
Hard containment for enterprise AI agents. Built on Apple Endpoint Security to provide governance where standard model alignment can’t reach.

Clearance-aware filesystem intelligence
Turn selected macOS folders into a private, encrypted semantic index. Search by meaning, answer only from cleared results, and keep tamper-evident file history when compliance matters.

Swift-native agent runtime
On-device model routing and local tool execution, built natively for Apple silicon. Fully-managed or BYOK modes.

Agentic coding workspace
Powered by the Cosmic Duck engine. The agentic platform for developers who want absolute control over their environment and provider keys.

Your storefront, and everything behind it.
Need a store? We design and build bespoke websites and online shops, with AI assistants built in if you want them. Our store designer, app.lutuno.com, has AI on hand to help you find products to sell, answer customer emails, and clear the day-to-day busywork, never to replace your team, just to help the people you already have get more done. We run it all on Lutuno, our own commerce platform: every merchant gets their own shop at yourname.lutuno.store, or a domain of their own, and you keep the data, the customers, and the margins.
Want to dropship? It's built in. Lutuno integrates directly with the AliExpress, CJ Dropshipping, and BigBuy APIs, so you can source products and fulfil orders without ever leaving your store. Running your own supplier or back-office system instead? We build custom APIs that wire your source straight to the web.

Enterprise engineering
How we fund the research.
We don't rely on venture capital. We fund our R&D and product portfolio by taking on bespoke engineering for clients whose problems overlap with our expertise.
Bespoke Engineering
From marketing sites to production systems. We ship software on modern stacks (TypeScript, Rust, Swift, Go) with a heavy bias toward native performance and local-first architecture.
Cloud Infrastructure
When we do go to the cloud, we design for scale. We've architected multi-region systems scaling across thousands of GPUs on Google Cloud, Cloudflare, and Firebase.
AI Integration
We build intelligence that ships to production, not demoware. We operate a platform integrating ten model providers behind a single API, building robust AI agents and automated workflows for enterprise teams.
