crossbeam vs rayon

Short answerBy steady daily use, rayon runs at 1,615,491 downloads on a quiet day against 374,913 for crossbeam (4.3x), and 11,972 crates depend on rayon against 1,418. Pick crossbeam if you build your own concurrency: channels, scoped threads, lock-free structures. Pick rayon if you just want a loop to run on all cores.

Bottom line: rayon is built on crossbeam's deque; most apps want rayon, libraries want crossbeam.

Which to pick

  • crossbeam if you build your own concurrency: channels, scoped threads, lock-free structures.
  • rayon if you just want a loop to run on all cores.

Downloads are not quality. The quiet-day baseline is our steadiest public number for real use (release-day spikes from mirrors and CI removed), and reverse dependencies count maintainers who chose the crate. How we compute it.

Each crate in detail

  • crossbeam: Tools for concurrent programming
  • rayon: Simple work-stealing parallelism for Rust
