Engineering @ Cosmonic

Recently, we launched the Cosmonic Control Technical Preview, giving platform engineering teams the chance to try our enterprise control plane for managing WebAssembly (Wasm) workloads in cloud-native environments.

Cosmonic Control integrates seamlessly with existing cloud native standards, technologies, and estates, so you can deploy and manage Wasm workloads with industry-standard patterns and tooling, such as GitOps with Argo CD.

In this blog, we'll take a look at how Cosmonic Control integrates with Argo CD, enabling platform engineering teams to manage ultra-dense sandboxed platforms with Wasm using their existing GitOps approach. Then we'll walk through deploying Cosmonic Control and a Wasm component with Argo CD.

Cosmonic is proud to announce the launch of our Cosmonic Control Technical Preview for platform engineering teams.

Cosmonic Control is the enterprise control plane for managing ultra-dense sandboxed platforms with WebAssembly (Wasm). Building on the Incubating CNCF project wasmCloud, Cosmonic Control gives platform engineering teams a single interface and unified control plane to…

Today, we’re launching the Technical Preview for Cosmonic Control, an enterprise control plane for managing WebAssembly (Wasm) workloads in cloud native environments.

Cosmonic Control is built on the open source foundations of wasmCloud, an Incubating project at the Cloud Native Computing Foundation (CNCF) that originated with the founders of Cosmonic.

Since we’re launching an enterprise product built on open source, now seems like a good time to lay down some of our guiding principles and commitments.

We’re back on the road, and bringing something very special to Europe this Spring. Our annual European trek to KubeCon + CloudNativeCon Europe 2025 is a particularly momentous one as we introduce Cosmonic Control.

If you’re in London for KubeCon, come and find out more at Cosmonic booth S680 and CNCF wasmCloud project booth on Wednesday afternoon/evening. As usual, the team will be on stage during both events and so here’s a summary of where we’ll be, and what we’re talking about this year. We’re looking forward to catching up with everyone in London!

If you want to use AI agents for enterprise development, you’ve got some big security questions to answer. For example: How do you limit the capabilities that agentic developers can access in your environments? You don’t want to give them access to your whole platform, and you probably shouldn’t just YOLO AI-generated code into a container and deploy.

But what if you could give AI agents a custom sandbox with a limited number of capabilities? WebAssembly makes it possible, and wasmCloud gives you a way to deploy agents’ code with custom capabilities injected at runtime—all executing safely within the sandbox.

In this blog, we’ll walk through how it all works as part of a hands-on demo that you can try for yourself at KubeCon EU 2025 in London.

ARLINGTON, VA. 24th March, 2025. Cosmonic announces the launch of Cosmonic Control, a control plane for managing distributed applications across any cloud, any Kubernetes, any edge, or on premise and self-hosted deployment. With Cosmonic Control, enterprise platform engineering teams create polyglot golden templates and components, allowing developers to write applications once and deploy them anywhere.

As wasmCloud adoption has accelerated, we've seen an increased demand for more sophisticated benchmarking options. To fulfill this need, wasmCloud maintainer Taylor Thomas recently introduced a new wasmCloud benchmark Helm chart for users running wasmCloud on Kubernetes.

Exploring a web application that performs simple CRUD operations (Create, Read, Update, Destroy) is a great way to understand new application paradigms.

In this walkthrough, we'll unpack a simple CRUD application in Go, compile the code to a WebAssembly component, and run it on wasmCloud using swappable, vendorless capabilities for HTTP service and key-value storage.

Alongside wasmCloud 1.3, we introduced a major refinement on the wash dev subcommand that gives WebAssembly component developers a hot-reloading developer loop across all of our supported languages—and leverages plug-and-play capabilities to make application development even smoother.
