## Health v2 (maintenance only)
Score: 88/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 66, longevity 100
- inputs: {"age_days": 5709, "days_push": 7, "days_rel": 16, "gap_med": null, "n_releases_24m": 1}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
DMD is the reference compiler for the D programming language, a statically typed systems and applications language with C-like syntax and native performance. Together with the Phobos standard library and druntime, it compiles and runs D programs across major platforms.

## Use cases
- compile D programs
- learn the D programming language
- write fast native systems code
- use the D standard library Phobos
- build high-performance applications in D
- contribute to a compiler codebase

## When to choose
- you want a statically typed, native-performance language with modern conveniences
- you need systems-level access with C-like syntax and easy C interop
- you want the reference implementation of D with active releases

## When to avoid
- you need a large ecosystem of third-party libraries or broad industry adoption
- you want a managed runtime or VM-based language
- your team relies on niche tooling only available for mainstream languages

## Facets
- artifact type: cli-tool
- maturity: active
- function: compiler, programming-language, cli, developer-tools
- domain: programming-languages, compilers, developer-tools
- platform: windows, cross-platform, cli
- tags: dlang, dmd, phobos, native-code, systems-programming, reference-compiler, druntime, command-line, linux, macos
