## Project history and usage

wzprof is a pprof-compatible profiler for WebAssembly programs running on the wazero runtime. It is a niche developer tool, but a meaningful one for the Go and WebAssembly packaging ecosystem because it brings familiar Go profiling workflows to guest Wasm modules.

### Project history

The project README describes wzprof as a profiler built on top of wazero, able to collect CPU and memory profiles while WebAssembly modules execute. It was presented publicly in the WebAssembly and cloud-native conference circuit, including Civo Navigate Europe 2024 and KubeCon + CloudNativeCon India 2024.

wzprof sits on top of wazero's trajectory as a pure-Go, zero-dependency WebAssembly runtime. Wazero's own history page says it began as Takeshi Yoneda's hobby project in mid-2020 and became a Tetrate-sponsored top-level project in late 2021; wzprof builds on that runtime rather than implementing a separate Wasm engine.

### How it is used

Users can run wzprof as a CLI against a Wasm binary to emit CPU or memory profile files, then inspect them with the standard go tool pprof workflow. Library users can integrate the profilers with a wazero.Runtime through wazero's experimental function-listener hooks.

The tool supports pprof-style CPU samples, on-CPU time, memory allocation tracing for selected allocation functions, DWARF symbolization for C/Rust/Zig-style modules, and special stack handling for Go 1.21+ and debug-symbol CPython 3.11 guests.

### Why package nerds care

wzprof matters to package nerds because it is a small example of WebAssembly's tooling stack becoming more like native language ecosystems: not just runtimes and compilers, but profilers, symbols, heap views, and workflows that integrate with existing developer muscle memory.

### Timeline

- 2020: wazero begins as a hobby project, according to wazero's official history.
- 2021: Tetrate sponsors wazero as a top-level project.
- 2023: wzprof publishes early releases and documents pprof-compatible CPU and memory profiling for WebAssembly.
- 2024: wzprof is presented at Civo Navigate Europe and KubeCon + CloudNativeCon India.
