## What it is
Nuclide was a collection of features for the Atom editor providing IDE-like functionality for web and native mobile development, with first-class support for React Native, Hack, Flow, and iOS. Facebook retired the project in 2018, and the source code now lives in the Facebook Open Source Archive.

## Use cases
- get IDE features like autocomplete and debugging inside Atom
- develop React Native apps with an integrated debugger and inspector
- write Hack and Flow code with type hints and jump to definition
- debug native iOS apps built with Buck
- do remote development from Atom over SSH

## When to choose
- you are already locked into Atom and want IDE features for Hack, Flow, or React Native
- you want to fork or study the archived source for language server integrations

## When to avoid
- you need a maintained IDE - the project was retired in 2018 and receives no updates
- you develop on Windows, which was never fully supported
- you use modern editors like VS Code, which support the same language servers
