What users praise
- • Hardware isolation via per-sandbox Linux kernel for untrusted workloads.
- • Fast startup suitable for per-request sandboxes, often faster than Docker.
- • Host-side secret injection prevents secrets from ever entering the VM.
What frustrates them
- • Lacks GPU support, limiting its use for compute-heavy AI/ML tasks.
- • Small community and ecosystem compared to mature competitors like Docker.
- • No single daemon model may confuse users expecting persistent background service.
