We ship native drivers in Go, Rust, and Zig to unlock shard-aware routing and real load balance. Same protocol, real scale.
Drop-in compatible with NATS. Use your existing clients and the protocol still works. Nothing breaks, nothing rewrites.
But our native drivers unlock shard-aware routing and server-guided load balancing, keeping traffic local and cores evenly fed. That is where the real throughput comes from.
Kernel-bypass I/O. Zero syscall overhead, batched completions. Linux 5.1+.
Full kernel bypass. Userspace networking. Dedicated NIC required.
Pioneered deterministic simulation testing. We adopted their VOPR approach because finding bugs before production is the only way.
Proved that thread-per-core architecture delivers. No locks, no contention, just raw throughput.
Relentless pursuit of speed. Pushing boundaries, never settling. The mindset that faster is always possible.
A language for system programming that prioritizes performance and correctness. No hidden allocations, no hidden control flow.
