## Health v2 (maintenance only)
Score: 67/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 78, release rhythm 35, longevity 100
- inputs: {"age_days": 3844, "days_push": 134, "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 list of programming languages implemented in Rust, maintained as a directory for inspiration and comparison. It catalogs projects like Deno, RustPython, Gleam, and Boa with descriptions and activity status.

## Use cases
- find programming languages written in rust
- get inspiration for building my own language in rust
- discover rust-based compilers and interpreters
- compare existing language implementations before starting a new one
- find embeddable scripting languages for rust projects
- research examples of language tooling built in rust

## When to choose
- you want a directory of language implementations written in Rust for research or inspiration
- you are designing a new language and want prior art to compare against
- you are looking for Rust-based interpreters, compilers, or DSLs to reuse

## When to avoid
- you need a runnable tool or library rather than a reference list
- you need guaranteed completeness or rigorous maintenance, since the list is explicitly probably incomplete
- you need languages not implemented in Rust

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: programming-languages, awesome-lists, developer-tools
- platform: cross-platform
- tags: awesome-list, curated-list, rust, compilers, reference
