It exposes a high-level API for creating stores, modules, instances, and calling exported functions, as well as importing Python functions into WebAssembly. The package ships as a precompiled wheel with no external runtime dependencies, making installation straightforward.\n\nThe runtime is actively maintained and follows Wasmtime's versioning scheme, releasing a new major version monthly. This means dependency specifications need regular updates to stay current. It supports modern Python versions (3.9 through 3.14) and PyPy on 64-bit Windows, macOS, and Linux systems. The package is suitable for embedding WebAssembly execution in Python applications, whether for sandboxed computation, plugin systems, or interoperability with WebAssembly-based libraries.","worth_installing":"Yes. Wasmtime is a mature, actively maintained runtime with low install friction, no runtime dependencies, and broad platform support. The monthly major-version release cycle requires discipline in dependency management, but the package is well-documented and widely used. Install it if you need to execute WebAssembly from Python; verify the license terms for your use case first."},"id":"wasmtime","links":{"html":"https://skillfed.io/packages/wasmtime","md":"https://skillfed.io/packages/wasmtime.md","pypi":"https://pypi.org/project/wasmtime/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-20","license_spdx":"Apache-2.0 WITH LLVM-exception","license_treatment":"unclear","name":"wasmtime","python_support":"supports_current","summary":"A WebAssembly runtime powered by Wasmtime"},"popularity":{"monthly_downloads":1897257,"position":3449,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"47.0.1"}
