Kuasar is a multi-sandbox container runtime written in Rust that provides a unified sandbox abstraction on top of containerd's Sandbox API. It supports multiple isolation technologies including microVMs (Cloud Hypervisor, QEMU, StratoVirt), WebAssembly runtimes (WasmEdge, Wasmtime), app kernels (Quark), and runC, with an optimized framework that replaces shim processes for faster container startup.
Use cases
- run containers with microvm isolation on kubernetes
- run wasm workloads alongside regular containers on one node
- reduce container startup time and shim overhead
- unified sandbox management for containerd
- choose between different container isolation levels per workload
- secure multi-tenant container execution
When to choose
- you need multiple sandbox types (microVM, wasm, runc) managed through one runtime
- you use containerd and want sandbox as a first-class citizen
- container startup speed and shim overhead are critical
- you want a Rust-based, CNCF-ecosystem container runtime
When to avoid
- you just need a standard container runtime without sandboxing (plain containerd/runc suffices)
- you require Firecracker support, which is still planned rather than shipped
- your stack is Docker-centric rather than containerd/Kubernetes-based
