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. ### Related projects - wazero is the underlying Go WebAssembly runtime. google/pprof is the profile visualization and analysis tool whose workflow wzprof targets. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** wzprof - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Source-control packages](https://pkg.so/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [go](https://pkg.so/brew/go/) - Build dependency declared by Homebrew. - [emscripten](https://pkg.so/brew/emscripten/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [binaryen](https://pkg.so/brew/binaryen/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [wasmtime](https://pkg.so/brew/wasmtime/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [wabt](https://pkg.so/brew/wabt/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [bloaty](https://pkg.so/brew/bloaty/) - Shares pkgdb curated category or tags: cli, developer-tools, profiler. - [wasm-tools](https://pkg.so/brew/wasm-tools/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [wasm-pack](https://pkg.so/brew/wasm-pack/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [wasmer](https://pkg.so/brew/wasmer/) - Shares pkgdb curated category or tags: cli, developer-tools, webassembly. - [async-profiler](https://pkg.so/brew/async-profiler/) - Local package facts share a topical domain.
