AI-Generated Review

What is carbon_fiber?

Carbon Fiber is a drop-in Ruby Fiber Scheduler that turns blocking stdlib calls like Net::HTTP.get, TCPSocket, Mutex, Queue, and Process.spawn into concurrent operations on a single thread—no code changes needed. It leverages io_uring on Linux and kqueue on macOS for high-performance I/O, and plugs directly into the Async framework as a swappable backend. Ruby devs get instant concurrency for HTTP clients, servers, and subprocesses using plain Ruby syntax.

Why is it gaining traction?

Benchmarks on AWS show it outperforming Async by 14-29% on HTTP servers/clients, TCP echo, and connection pools, making it the fastest pure Ruby Fiber Scheduler tested. The pure-Ruby fallback ensures it works everywhere, even Windows, without Zig compilation hassles. Its github high performance edge shines in real workloads like fan-out HTTP APIs or cascading timeouts, drawing devs chasing github high availability without ecosystem lock-in.

Who should use this?

Ruby backend devs building high-throughput HTTP services, like API gateways or web scrapers hammering endpoints. Async users wanting faster backends for rate-limited crawls or parallel downloads. High performance athletes in Ruby optimizing single-threaded concurrency for carbon fiber-like strength in lightweight apps.

Verdict

Early alpha with 12 stars and 1.0% credibility score—docs are solid, benchmarks rigorous, but test coverage and production miles are thin. Try it for perf-critical prototypes if you're on Ruby 3.4+ and Linux/macOS; fallback saves you otherwise.
