Fast, daemon-free container runtime built on systemd-nspawn. 50ms cold starts. No idle overhead. Cryptographic verification at every layer.
Most container runtimes add layers on top of the kernel. Voltainer uses what's already there. No containerd. No runc. No namespace juggling at runtime.
Voltainer runs containers without a background daemon eating your RAM. Drop-in OCI compatibility means your existing images work unchanged.
Zero background processes. Zero idle memory. Your container runs as a direct systemd service. No polling, no wasted cycles.
Images are verified at runtime, not just download-time. If bytes don't match signatures, containers don't start. Period.
seccomp and Landlock profiles are derived from image contents. No manual policy writing. No CVE-of-the-week scrambles.
Containers run as systemd services with full journal logging, restart policies, and dependency management. Production-ready from day one.
Your existing Docker images work unchanged. No re-building, no migration pain. Just faster, more secure execution.
Mounts TinyVol images directly, applies pre-computed security policies, and starts your process. That's it. No extraction, no overhead.
Real benchmarks on real hardware. No cherry-picked results.
