Experience the next generation of JavaScript performance. Built with modern C++, optimized for high-throughput, and designed for simplicity.
Z8 intelligently switches between low-latency and high-throughput I/O. It detects your workload and optimizes buffers in real-time, making it up to 16x faster than Node.js in burst file operations.
Professional-grade async I/O with a smart thread pool. Z8 handles 500+ concurrent file operations 1.5x faster than Node.js, Bun, and Deno without thread explosion.
Native support for ES Modules, Temporal API, node:fs/promises, and modern C++23 backend ensures your code runs on the edge of innovation.
Unlike Node.js/Deno/Bun which clamp timers to 1ms minimum, Z8 respects your exact timing needs. Perfect for high-frequency tasks and game loops.
Full node:fs and node:fs/promises support with both sync and async methods. Drop-in replacement for Node.js file operations with superior performance.
Easy distribution with a single binary. No complex dependency hell, just one file to run your entire application.
