## Health v2 (maintenance only)
Score: 75/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 95, release rhythm 35, longevity 100
- inputs: {"age_days": 2465, "days_push": 33, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Silicon is a high-performance, middleware-oriented C++14 HTTP web framework. The project has been rewritten and merged into the Lithium libraries, so new users should use matt-42/lithium instead.

## Use cases
- build a fast http api in c++
- serve  endpoints with a c++ web framework
- compose middleware-based request handling in c++
- build a backend server with database access in c++
- replace heavy web frameworks with a lightweight c++14 option

## When to choose
- you need a high-performance, low-overhead C++ HTTP backend
- you want a middleware-oriented design with compile-time routing
- you are already invested in the Silicon/Lithium ecosystem

## When to avoid
- starting a new project - use matt-42/lithium instead
- you need a framework with active community and frequent releases
- you want a batteries-included framework with extensive documentation and ecosystem

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, http-server, middleware, routing, serialization, database
- domain: web-development, backend, apis, developer-tools
- platform: cpp, cross-platform
- tags: c-plus-plus, high-performance, http-backend, metaprogramming, superseded-by-lithium, linux, macos
