Everything You Need

Built from scratch for performance, security, and developer experience.

25x faster
🚀Sub-5ms Cold Starts
Copy-on-write memory snapshots enable instant function initialization. No more cold start penalties.
10x smaller
💾Minimal Memory Overhead
Less than 500KB per instance vs 5MB for Firecracker. Run more workloads on the same infrastructure.
15x faster
⚡High-Performance I/O
io_uring-based async I/O delivers over 200K block IOPS. Perfect for database-heavy applications.
🔐Multi-Layer Security
Defense in depth with WASM sandbox, Intel MPK, Seccomp, Landlock, namespaces, and cgroups.
🐳Docker Compatible
Deploy existing OCI containers without modification. Seamless migration from other platforms.
🌐Global Edge Network
