## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2886, "days_push": 680, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated awesome-list of WebAssembly runtimes, virtual machines, and compilers that execute or compile Wasm. Each entry includes implementation language, compiler framework, and maintenance status.

## Use cases
- find a webassembly runtime for my project
- compare wasm virtual machines like wasmtime wasmer wasm3
- list of webassembly compilers and runtimes
- which wasm runtimes are actively maintained
- embed a wasm runtime in my application
- learn about webassembly execution engines

## When to choose
- you need to survey the WebAssembly runtime ecosystem before picking one
- you want a quick reference of wasm VMs grouped by language and maintenance status

## When to avoid
- you need an actual wasm runtime rather than a list of them
- you need detailed benchmarks or performance comparisons between runtimes

## Facets
- artifact type: learning-resource
- maturity: active
- function: wasm, developer-tools
- domain: web-development, developer-tools, awesome-lists
- platform: cross-platform
- tags: awesome-list, webassembly, wasm-runtime, curated-list, virtual-machine
