What is wasmCloud?

wasmCloud is an open source project from the Cloud Native Computing Foundation (CNCF) that enables teams to build polyglot applications composed of reusable Wasm components and run them—resiliently and efficiently—across any cloud, Kubernetes, datacenter, or edge.

Build

Faster Development Cycles

Leverage reusable, polyglot, Wasm components on a reliable, distributed platform.

Centrally Maintainable Apps

Reusable, version-controlled components empower platform teams to maintain thousands of diverse apps centrally.

Integrate with Existing Stacks

wasmCloud has first-tier support for Kubernetes, AWS, Azure, GCP, Jenkins, Github Actions, ArgoCD, Backstage, Chainguard, Databases, Messaging, and more.

Compose

Development Without Lock-In

Define application dependencies at runtime via contract driven interfaces leveraging different vendors across deployments, dev, QA, or prod.

Truly Portable Apps

Run the same Wasm application across operating systems and architectures—no new builds required. Linux, MacOS X, Windows, ARM, x86, and more.

Custom Capabilities

Easily extend the secure wasmCloud host at runtime to support custom dependencies, hardware, or business contracts.

Run

Scale-to-Zero with Zero Cold Starts

Sub-millisecond start times and vertical autoscaling means workloads scale to the demand.

Reliable, Fault-Tolerant Apps

Horizontal scaling with automated fail-over gives apps capability-level resiliency, reliability, and scalability.

Deploy Across Clouds

Close to your users, with local-first routing and at-most-once delivery, wasmCloud delivers cross-region, cross-cloud, and cross-edge capability-level resiliency to every deployment
