## What it is
LambdaNative is a cross-platform development environment and framework written in Scheme (based on Gambit-C) that builds native applications for mobile, desktop, and embedded targets from a single source. It was developed at UBC and is used in clinical research applications, but the project is now sunset and seeking new maintainers.

## Use cases
- build native mobile apps in Scheme
- write cross-platform apps from a single codebase
- develop apps for iOS and Android with functional programming
- target embedded devices like OpenWrt
- build desktop applications in Scheme

## When to choose
- you want to develop native apps in Scheme
- you need one codebase across mobile, desktop, and BSD/embedded platforms
- you are maintaining or extending an existing LambdaNative project

## When to avoid
- you need a framework with active maintenance and community support
- you prefer mainstream languages and ecosystems
- you need modern mobile platform features or store compliance guarantees

## Facets
- artifact type: framework
- maturity: maintenance
- function: mobile-framework, gui, programming-language
- domain: cross-platform, mobile-development, developer-tools, desktop-applications
- platform: windows, bsd, cross-platform
- tags: scheme, gambit-c, embedded, openwrt, sunset, cross-platform, android, ios, macos, linux
