Score: 8.0/10 (Innovation: 8, Technical: 9, Documentation: 8, Utility: 7)

Runloom brings Go-style stackful coroutines to Python, using hand-rolled assembly context switches and a work-stealing scheduler to achieve near-Go-level concurrency without requiring async/await. Its ability to run millions of fibers across multiple cores in free-threaded CPython is a significant innovation, though niche due to dependency on Python 3.13t.

Target audience: backend devs, data engineers
