Product Decisions This Supports

Enables building high-performance, I/O-bound services (e.g., API gateways, real-time data processors) by handling thousands of concurrent connections with minimal server resources, directly reducing cloud infrastructure costs.
Supports roadmap decisions for modernizing legacy PHP systems by replacing blocking synchronous patterns with non-blocking async code, improving throughput without requiring thread-based concurrency models.
Justifies a "build" approach over off-the-shelf frameworks for specialized use cases (e.g., custom HTTP servers, database drivers) where full-stack frameworks like Laravel introduce unnecessary overhead and lack fine-grained concurrency control.

When to Consider This Package

Adopt when building applications with high concurrency needs (e.g., >1K simultaneous connections), heavy external I/O operations (APIs, databases, file systems), or real-time event-driven workflows, using PHP 8.1+.
Avoid for CPU-bound tasks (e.g., complex calculations), simple CRUD applications, or projects requiring rapid feature development where framework conventions (e.g., Laravel) outweigh concurrency benefits.
Look elsewhere if using PHP <8.1, needing pre-built HTTP server solutions (use amphp/http-server instead), or when team expertise in async patterns is lacking—opt for simpler synchronous tools or managed services like AWS Lambda.

Executives: "This package lets us handle 5–10x more traffic on the same infrastructure by eliminating blocking I/O bottlenecks, directly cutting cloud costs while future-proofing our platform for explosive growth. It’s a strategic investment in scalability—not just a technical upgrade."
Engineering: "It provides a lightweight, modern foundation for writing clean, non-blocking code using PHP 8.1 fibers—no callbacks, no generator boilerplate. We can build high-performance services like our
