# Levyer > The platform designed for freedom. Built for control. Levyer is an application platform for organisations that want to build software on their own terms — secure, compliant, independent, and built to last. It gives leadership, operations, and engineering teams a single foundation to govern how software is built, where it runs, who controls it, and what it costs. Levyer is currently pre-launch and onboarding its first design partners. ## What Levyer is Levyer is not an orchestrator, a CI/CD tool, or a cloud wrapper. It is an application layer that sits above your infrastructure. Kubernetes, bare metal, Docker hosts, and cloud-managed runtimes are all valid deployment targets underneath Levyer — they are the infrastructure Levyer runs on, not what it competes with. At the application level, Levyer defines how software is structured, how modules communicate, how it is secured, deployed, governed, observed, and documented. Your team writes pure business logic. Levyer handles everything from the application model downwards. The execution model is built on WebAssembly (WASM + WASI). This is not an implementation detail — it is the architectural foundation that makes Levyer's security guarantees, portability, and interface contracts structurally enforced rather than configured. ## Who Levyer is for - **Engineering teams** who want to focus on business logic without managing infrastructure boilerplate, communication protocols, or security configuration. - **Operations teams** who need central control over deployments, environments, cost, and compliance across the full application estate. - **Leadership and management** who need visibility, governance, and the ability to enforce organisational policy without depending on individual teams to get it right. Levyer is built for the whole organisation — not just engineering. ## The problem Levyer solves Modern organisations unknowingly give away control. Application code becomes entangled with cloud-provider ecosystems and proprietary services that are nearly impossible to reverse. Security and compliance are managed reactively. Engineering teams spend the majority of their time on infrastructure plumbing. As organisations grow, nobody has a clear, current view of how systems actually work. The result: locked in to vendors, exposed to security risks, struggling to meet regulatory requirements, unable to move decisively when the landscape changes. ## Core capabilities ### Digital sovereignty — structural, not aspirational Every application built on Levyer is portable by design. No dependency on any specific cloud provider, infrastructure service, or communication technology. Moving between cloud providers, on-premise, or hybrid is a configuration change — not a development project. EU data residency, GDPR, and data sovereignty requirements are met as a deployment decision. ### Security by design Security is not a layer added on top. It is embedded in the execution model. Every module runs in a fully isolated WebAssembly sandbox with strict capability-based access control — a module can only access the specific resources (files, network, environment variables) that have been explicitly granted to it. Nothing is accessible by default. Blast radius is structurally contained. Transport encryption, secure inter-module communication, and security hardening are applied automatically at deployment. Cryptographic protocols are independently upgradeable, including a path to post-quantum cryptography. ### Compliance by default Regulatory compliance is built into every deployment. GDPR, SOC 2, and ISO 27001 standards are embedded in the provisioning and deployment pipeline. Compliance is a platform concern — it cannot be bypassed through application code or infrastructure misconfiguration. As regulations evolve, compliance controls are updated centrally and propagate everywhere. ### Central control plane Leadership and operations get a single control plane for the entire software estate — across every team, application, environment, and provider: - Cost management: budgets, spend alerts, hard limits per team, application, or environment - Security posture: enforce policies and apply patches across all applications from one place - Compliance and governance: define policies once, enforce everywhere, audit trails out of the box - Scaling: define behaviour centrally; applications scale automatically within defined boundaries ### Environments An environment in Levyer is more than a stage label. It is a complete, centrally defined deployment target that encapsulates the provider, the deployment strategy, and the infrastructure topology. Switching between environments — AWS, on-premise, hybrid, single-server — is a platform configuration change. No application code is ever affected. ### Living documentation — always current Architecture diagrams, data flow diagrams, and process diagrams are generated automatically from the actual state of the platform. They are not documents — they are live views. When something changes, the diagram updates. Data protection impact assessments (DPIAs), audit documentation, and architecture reviews are supported by generated, accurate content. ### Full observability Metrics, distributed tracing, structured logging, and alerting across the entire application estate in one view. Follow a request as it travels across multiple applications and services from entry to resolution. ### Marketplace Ready-to-use applications and integrations that can be deployed into any environment with a single click — authentication services, CMS platforms, data pipelines, monitoring stacks, analytics tools. Every marketplace application is fully portable and inherits all platform security and compliance guarantees automatically. ## The execution model — WebAssembly Levyer's runtime is built on WebAssembly (Wasm) with WASI. This provides four properties no other runtime combines: 1. **Security by design.** Every module runs in a strict sandbox with capability-based access control. Nothing is reachable unless explicitly granted — no network, no filesystem, no environment variable. 2. **Language-agnostic.** WebAssembly is a compilation target for most major languages — Rust, Go, TypeScript, Python, and more. Teams work in the language that suits them. 3. **Interface-first contracts.** Modules communicate through typed interface definitions (WASI/WIT), not bespoke protocols. Integrations are explicit, versionable, and safe to evolve. 4. **Tiny and portable.** Wasm modules are compact, start in milliseconds, and run identically across cloud, on-premise, edge, and local environments — with no runtime dependency or infrastructure assumption. ## Deployment options - **Any major cloud provider** — AWS, Azure, GCP, and others via provider plugins - **On-premise** — private data centre deployments - **Single server** — for small-scale or air-gapped deployments - **Hybrid** — cloud and on-premise simultaneously - **Local** — full development and testing without cloud dependencies - **Levyer Cloud** — fully managed, no infrastructure required Migrating from Levyer Cloud to self-hosted is always a configuration change, never an application rewrite. Sovereignty is preserved regardless of hosting model. ## Open source Levyer's core is open source. The platform is auditable, extensible, and free from closed-source lock-in at the foundation. ## Current status Levyer is pre-launch. The architecture and model described here reflect the platform being built with early design partners. We are onboarding our first design partner organisations now.

It provides a single foundation to govern how software is built, where it runs, who controls it, and what it costs. **Who is Levyer for?** Organisations that want structural independence from vendors and central control over their software estate. It serves leadership, operations, and engineering teams who need a unified platform for cost management, security governance, compliance enforcement, and deployment flexibility across any infrastructure. **How is Levyer different from Kubernetes?** Levyer sits a layer above Kubernetes — it is an application platform, not infrastructure. Kubernetes can be one of the deployment targets underneath Levyer, alongside bare servers, Docker hosts, or cloud-managed runtimes. Where Kubernetes manages containers and workload scheduling, Levyer gives you a complete application layer: how software is structured, how it communicates, how it is secured, deployed, governed, and observed — all the way up to the business level. **Why does Levyer use WebAssembly?** High security sandboxing with strict capability control, a language-agnostic compilation target, typed interface definitions (WASI/WIT) for explicit module contracts, and tiny portable modules that run identically anywhere — with no runtime dependency or infrastructure assumption. **Can Levyer run on AWS, on-prem, and hybrid setups?** Yes. Levyer runs on any major cloud provider, on-premise, on single servers, and in hybrid configurations. Switching between deployment targets is a platform configuration change — no application code is ever affected. **What stage is Levyer at today?** Pre-launch. Onboarding first design partners now. The platform described here is being built with early adopters before general availability. ## Links - Homepage: https://levyer.com/ - Early access: https://levyer.com/#access - Documentation: https://levyer.com/docs - Open source: https://github.com/levyer-com - Contact: contact@levyer.com
