What is tiny_coro-build_your_own_MN_scheduler?

This lightweight GitHub repo lets you build your own M:N asynchronous runtime using C++20 coroutines, mapping many tasks to few threads for high-concurrency apps. It handles scheduling, reactor-based I/O, and basics like HTTP servers out of the box, solving the black-box problem of libraries like Seastar by exposing core mechanics. Devs get a minimal, educational framework to spawn coroutines, await I/O, and benchmark against Go.

Why is it gaining traction?

Its hook is pure education: follow docs to construct a work-stealing scheduler with EBR memory safety and zero-copy features, hitting 186k QPS in HTTP benchmarks rivaling optimized Go servers. No deps beyond C++20 stdlib, cross-platform on Linux/macOS, and tiny footprint appeal to coroutine curious devs tired of opaque async stacks. Stands out as a betfair lightweight GitHub alternative for async tinkering.

Who should use this?

C++ systems programmers learning coroutines for custom runtimes. Backend engineers prototyping lightweight I/O servers before production frameworks. Educators building tutorials on M:N scheduling and async primitives.

Verdict

Grab it for educational deep dives—docs guide you from zero to running scheduler with clear benchmarks. 1.0% credibility score and 10 stars signal early maturity, so stick to learning, not prod; lacks broad tests but shines for motivated C++20 explorers.
