Platform Engineering
is Expensive

Platform engineering teams face significatn challenges with containerized infrastructure - expensive to build, mantain, and operate redundantly.

High Cost of Idle Infrastructure

With average containerized CPU utilization under 20%, can you more efficiently utilize what you already pay for?

Is Data locality going to double your cloud bills?

Expensive App Maintenance

You can deploy 1,000 containers on Kubernetes, but can you keep them up to date?

How many Teams fix the same CVE?

Cloud Agnostic

Is your technical debt so deep that you are stuck mantaining choices from 20 years ago? 

Can you take advantage of modern clouds & edges?

Deploy Now on Cosmonic
Cosmonic

Security Built In, Not bolted On

Cosmonic Control applies capability-driven isolation to every WebAssembly component, enforcing least privilege at runtime. You keep your existing Kubernetes guardrails (RBAC, admission, policies) while adding a tighter zero-trust boundary around application code.

Run More with Less: Cost-Efficient Compute

Components cold-start in microseconds and scale to zero, so redundancy doesn’t mean paying for idle pods. Cosmonic manages mulit-tenant CNCF wasmCloud hosts within K8s namespaces, respecting segmentation and policy. You can spread workloads across regions/zones without coupling reliability to always-on resources.

Enterprise-Grade Integrations

Cosmonic integrates deeply into your existing pipelines, operational controls, observability stack, and ingress/egress. Operators and CRDs give you declarative control of clusters, host groups, and workloads directly through kubectl, GitOps, and HPAs.

First Class Observability, Built In

Cosmonic supports OpenTelemetry and exports metrics, logs, and traces for both platform and component layers, giving clean separation and faster anomaly detection.

Containers and Components

Keep containers for what they do best and introduce WebAssembly where security and latency matter most. Cosmonic runs CNCF wasmCloud inside containers so both artifacts share governance, policies, and tooling.

Deploy Cosmonic Now

How does Cosmonic Control integrate with my existing Kubernetes environment?

Faq Arrow Faq Arrow

Cosmonic Control is a Kubernetes-native WebAssembly control plane that integrates seamlessly with your existing clusters, namespaces, and RBAC policies. There’s no need to replace or reconfigure your infrastructure — Cosmonic Control installs directly into your current Kubernetes environment using Custom Resource Definitions (CRDs) and an Operator. It works with your existing ingress, observability, and CI/CD tooling, making it easy for platform engineers to add WebAssembly components alongside containers without introducing new operational overhead. This means your existing governance, pipelines, and policies continue to function exactly as before — just faster, lighter, and more secure.

Can I deploy WebAssembly components alongside my existing containers?

Faq Arrow Faq Arrow

Yes. With Cosmonic Control, WebAssembly components and containers run side-by-side in the same Kubernetes cluster. This hybrid model lets you keep your trusted containerized workloads while adopting WebAssembly for high-density, low-latency, and secure workloads. Both share the same ingress/egress, observability, and CI/CD systems, so you can gradually migrate to Wasm-native microservices without disrupting existing workflows. For platform engineers, this means extending Kubernetes with a next-generation runtime layer that offers sub-millisecond startup times, tighter sandboxing, and drastically lower compute costs.

How do I connect Cosmonic Control to my existing CI/CD pipelines?

Faq Arrow Faq Arrow

Cosmonic Control integrates out of the box with popular CI/CD tools like GitHub Actions, ArgoCD, and Backstage, enabling declarative, signed, and immutable deployments. You can continue using your existing automation pipelines — just add Wasm components as new deployable artifacts. This approach gives platform teams a GitOps-friendly workflow where every deployment is traceable, secure, and auditable. By integrating with familiar systems, Cosmonic Control eliminates the need for new tools while accelerating delivery speed, ensuring consistent environments across clouds, edges, and on-premises deployments.

What observability and monitoring tools does Cosmonic Control support?

Faq Arrow Faq Arrow

Cosmonic Control includes first-class observability with OpenTelemetry, unifying logs, metrics, and traces across both containers and WebAssembly components. Platform teams gain full visibility into performance, latency, and resource utilization — all accessible through the same dashboards you already use with Prometheus, Grafana, or other monitoring stacks. This deep integration helps operators detect anomalies faster, maintain compliance, and optimize performance without retraining or adopting new tooling. Cosmonic Control makes Wasm workloads observable, debuggable, and manageable within the same telemetry fabric as Kubernetes.

How does Cosmonic Control reduce infrastructure and operational costs?

Faq Arrow Faq Arrow

Cosmonic Control dramatically improves resource efficiency with scale-to-zero workloads, sub-millisecond cold starts, and ultra-dense scheduling. Traditional containerized environments often waste up to 80% of CPU due to idle infrastructure. By contrast, Wasm components under Cosmonic Control start in microseconds and consume minimal memory, allowing thousands of workloads to run per node. The result is lower cloud bills, higher cluster utilization, and reduced redundancy. For IT executives, this means cutting operational costs without compromising reliability — achieving true cost-efficient compute at scale.

What security improvements does Cosmonic Control bring to my existing Kubernetes setup?

Faq Arrow Faq Arrow

Cosmonic Control introduces capability-based zero trust isolation to Kubernetes. Each WebAssembly component runs inside a secure, shared-nothing sandbox that enforces least privilege by design. Unlike containers that share broad system-level access, Wasm workloads only receive explicit capabilities — such as network, file, or messaging access — defined declaratively. This reduces the attack surface, prevents lateral movement, and enforces memory safety at runtime. Combined with Kubernetes’ native RBAC, admission, and policy controls, Cosmonic Control gives your platform defense-in-depth security for modern, multi-tenant workloads.

How does Cosmonic Control integrate with my existing Kubernetes environment?

Faq Arrow Faq Arrow

Cosmonic Control is a Kubernetes-native WebAssembly control plane that integrates seamlessly with your existing clusters, namespaces, and RBAC policies. There’s no need to replace or reconfigure your infrastructure — Cosmonic Control installs directly into your current Kubernetes environment using Custom Resource Definitions (CRDs) and an Operator. It works with your existing ingress, observability, and CI/CD tooling, making it easy for platform engineers to add WebAssembly components alongside containers without introducing new operational overhead. This means your existing governance, pipelines, and policies continue to function exactly as before — just faster, lighter, and more secure.

How does Cosmonic Control support long-term platform evolution and portability?

Faq Arrow Faq Arrow

Cosmonic Control enables enterprises to future-proof their platform architecture by bridging today’s container ecosystems with tomorrow’s WebAssembly-native systems. Because Wasm components are portable, composable, and language-agnostic, workloads can run anywhere — from cloud to on-premises to edge environments — without code changes. This empowers chief architects to design cloud-agnostic, modular systems that evolve over time without being locked into legacy infrastructure or vendor-specific runtimes. Cosmonic Control is your bridge to the next epoch of platform engineering — one that’s secure, efficient, and built for continuous innovation.

What is Sandbox MCP

Faq Arrow Faq Arrow

Sandbox MCP is a free and open-source plugin built on CNCF wasmCloud that lets you generate standards-compliant Model Context Protocol (MCP) servers as secure WebAssembly components.

It gives you a repeatable way to build MCP tools that are secure by default, portable, composable, and sandboxed—perfect for safely extending LLMs and agentic systems.
