wasmCloud is a CNCF incubating cloud native platform for building, deploying, and orchestrating WebAssembly component workloads across clouds, Kubernetes, datacenters, and edge environments. It runs polyglot microservices, functions, and agents as deny-by-default Wasm sandboxes with capability-based security, managed via the wash CLI and a Kubernetes operator.
Use cases
- run webassembly microservices on kubernetes
- deploy polyglot apps across cloud and edge
- replace containers with secure wasm sandboxes
- scale-to-zero serverless workloads with no cold starts
- orchestrate distributed wasm components with nats
- run lightweight workloads on edge devices
- enforce capability-based security for services
When to choose
- you want portable, ultra-dense workloads smaller and faster-starting than containers
- you need deny-by-default security with explicit capability grants
- you deploy across multiple clouds, regions, or edge with intermittent connectivity
- you want polyglot components (Rust, Go, TypeScript, Python) that interoperate
- you want to progressively adopt Wasm on existing Kubernetes tooling
When to avoid
- your team relies heavily on legacy container ecosystems and OCI-only tooling
- you need full OS access, GPUs, or system-level features Wasm sandboxes restrict
- your workloads depend on libraries or runtimes that don't compile to Wasm components
- you need a battle-tested GA platform and can't tolerate evolving v2 APIs
