Announcing Pyro Caml: The First Continuous Profiler for OCaml | Semgrep

▤ Summary

Semgrep has released Pyro Caml 1.0.0, a continuous profiler built for OCaml. The team created it because existing profilers did not work well under gVisor, did not support OCaml well, or imposed too much overhead for production use. Pyro Caml uses OCaml Memprof sampling, Runtime Events, and a Rust-backed Pyroscope integration to collect and ship profiling data with low overhead. The company says the tool has already run in production for months and helped uncover performance bottlenecks across large-scale code scanning workloads.
