Why We Built Levyer

The Problem We Kept Running Into

Every organisation we talked to had the same story. They moved to the cloud for speed and flexibility, and they got both — for a while. Then the bills arrived. Then the lock-in showed up in the form of proprietary APIs, managed services with no exit path, and compliance requirements that didn’t care which region their vendor had availability zones in.

The engineering teams were brilliant. The tooling was sophisticated. But the foundation underneath everything — where software runs, how it is secured, who controls the data — had quietly become someone else’s responsibility.

What We Set Out to Build

Levyer is an application platform with one guiding principle: your software should run on your terms.

That means:

• Any infrastructure. AWS, Azure, GCP, Hetzner, on-premise bare metal, a private data centre in a jurisdiction of your choice. The same application, the same behaviour, no code changes.
• Security by design. Every module runs in a WebAssembly sandbox. Capabilities are explicit. Nothing is reachable unless granted.
• No proprietary dependencies. Levyer’s model is based on open standards — WASI, WIT, and interface-first contracts. You are never tied to us either.

Why WebAssembly

We chose WebAssembly as the core runtime for four reasons that no other technology combines:

1. Isolation by default — every module is sandboxed at the capability level.
2. Language agnostic — teams write in Rust, Go, Python, TypeScript, whatever fits.
3. Portable — a module runs identically across cloud, edge, and on-premise.
4. Fast — cold start times measured in milliseconds, not seconds.

Where We Are Today

Levyer is pre-launch. We are working with our first design partners to refine the platform against real-world use cases — organisations that need structural independence from cloud vendors and central governance over their software estate.
