Its defining package-manager story is that it gives Go developers a runtime written in Go, avoiding CGO and native shared-library dependencies common in Wasm runtimes implemented in C, C++, or Rust. ### Project history The project history page says wazero began as Takeshi Yoneda's hobby project in mid 2020 and was sponsored by Tetrate as a top-level project in late 2021. The original motivation was to let Go programs embed WebAssembly host environments without relying on CGO-backed runtimes such as V8, Wasmtime, Wasmer, or WAVM. The official site says wazero 1.0 was released in March 2023. By that point, the project had positioned itself as both an embeddable Go library and a standalone CLI, with WebAssembly Core Specification compliance and a focus on cross-compilation-friendly deployment. The project later moved under the `wazero/wazero` GitHub organization while retaining Tetrate stewardship and branding in docs and package metadata. Release notes through the 1.x series document work on WASI support, compiler performance, Go version compatibility, experimental proposals, and security-oriented execution details. ### Adoption history wazero adoption tracks the rise of server-side and embedded WebAssembly in Go systems. The project history names plugin systems, proxy extension through Proxy-Wasm, server-side rendering, and Open Policy Agent-style policy/plugin use as motivating examples. The official homepage says the 1.0 release is used by many projects and production sites. Package metadata in this batch also shows distribution through Homebrew, Alpine, Nix, winget, and openSUSE, reflecting use both as a developer CLI and as a runtime dependency in Go-based tooling. ### How it is used Library users import wazero to run WebAssembly modules inside Go programs, define host functions, wire WASI, and let users write plugins in languages that compile to Wasm, including AssemblyScript, C, C++, Rust, Zig, Go, and TinyGo. CLI users run Wasm modules directly for testing, scripting, or packaging workflows. The zero-CGO design is especially useful for static binaries, cross-compilation, container images, and environments where adding a native Wasm runtime library would complicate builds or distribution. ### Why package nerds care wazero matters to package nerds because it changes the dependency tradeoff for WebAssembly in Go: a package can embed a runtime without dragging in a C ABI, libc assumptions, or platform-specific shared libraries. That makes it attractive for Homebrew formulae, distro packages, and small containers that prefer boring Go binaries. Its significance is also cultural. It belongs to the wave of Wasm-as-a-plugin-runtime tools, but it speaks fluent Go packaging: module import, no CGO, cross-compilation, and API integration rather than a separate server. ### Timeline - 2020: wazero begins as Takeshi Yoneda's hobby project. - 2021: Tetrate sponsors wazero as a top-level project. - 2023-03: wazero 1.0 is released. - 2024: 1.x releases continue with compiler, WASI, and Go-version support work. - 2025-2026: The project continues under the wazero GitHub organization with Tetrate branding and stewardship. ### Related projects - wazero is related to WebAssembly, WASI, Proxy-Wasm, TinyGo, Open Policy Agent, Wasmtime, Wasmer, V8, WAVM, and the older Go wasm runtime wagon that the wazero history page mentions. ### Sources - - - - - ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** wazero - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - wazero: normalized package name match | nixpkgs package indexes: pkgs/by-name/wa/wazero/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - wazero - 1.9.0-r12: normalized package name match | Alpine Linux edge package indexes: wazero from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | WebAssembly Core Specification 1.0 and 2.0 compliant runtime | https://wazero.io - zypper - wazero - 1.9.0-1.4: normalized package name match | openSUSE Tumbleweed package metadata: wazero from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | CLI tool and library to compile and run WebAssembly | https://github.com/tetratelabs/wazero - winget - Tetrate.wazero: normalized package name match | Windows Package Manager source index: Tetrate.wazero from https://cdn.winget.microsoft.com/cache/source.msix ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [wasm3](https://www.automicvault.com/pkg/brew/wasm3/) - Shares av.db curated category or tags: cli, language-runtime, runtime, wasm, webassembly. - [wasm-micro-runtime](https://www.automicvault.com/pkg/brew/wasm-micro-runtime/) - Shares av.db curated category or tags: cli, language-runtime, runtime, webassembly. - [spidermonkey](https://www.automicvault.com/pkg/brew/spidermonkey/) - Shares av.db curated category or tags: cli, language-runtime, runtime, webassembly. - [v8](https://www.automicvault.com/pkg/brew/v8/) - Shares av.db curated category or tags: cli, language-runtime, runtime, webassembly. - [bigloo](https://www.automicvault.com/pkg/brew/bigloo/) - Shares av.db curated category or tags: cli, language-runtime, runtime. - [chezscheme](https://www.automicvault.com/pkg/brew/chezscheme/) - Shares av.db curated category or tags: cli, language-runtime, runtime. - [chicken](https://www.automicvault.com/pkg/brew/chicken/) - Shares av.db curated category or tags: cli, language-runtime, runtime. - [clozure-cl](https://www.automicvault.com/pkg/brew/clozure-cl/) - Shares av.db curated category or tags: cli, language-runtime, runtime. ## Combined YAML source View the package source record on GitHub.
