rupert648/culpert
Culpert is a sampled heap-allocation profiler for Rust libraries and services. It works as a global allocator wrapper, attributes sampled allocations to spans (via tracing, Cloudflare foundations, or its own macro), exports pprof-compatible profiles, and includes a CLI with per-span reports and a diff subcommand for catching allocation regressions in CI before release.
Why now: Recently promoted on Mastodon as a new span-aware heap profiler with regression tooling; its low-overhead sampling and pprof compatibility make it notable in the Rust observability space.
Who it is for: Rust developers profiling memory usage in services and wanting per-span allocation regression checks in CI.
