Nuclide vs PlatformIO: What are the differences?

Nuclide: An open IDE for web and native mobile development, built on top of Atom (by Facebook). A unified developer experience for web and mobile development, built as a suite of packages on top of Atom to provide hackability and the support of an active community; PlatformIO: Next-generation IDE for IoT. PlatformIO is an open source ecosystem for IoT development. Cross-platform build system and library manager. Continuous and IDE integration. Arduino and MBED compatible. Ready for Cloud compiling.

Nuclide and PlatformIO can be primarily classified as "Integrated Development Environment" tools.

Some of the features offered by Nuclide are:

• Remote development. At Facebook, our web and back-end engineers work on remote development servers in our data centers. Nuclide provides a pair of packages that allow connections over SSH to a lightweight node daemon on the server, making possible remote file editing and syntax/type validation. Of course, this also works for VMs, enabling local development on HHVM, for example.
• Hack language support. The Hack codebase is one of the largest at Facebook. First-class Hack support — including syntax highlighting, type-checking, autocomplete, and click-to-symbol features — has been an important requirement on Nuclide from the start. We're also excited that the growing Hack community outside the company will be able to enjoy dedicated IDE support.
• Flow support. For both local and remote JavaScript development, Flow has brought type integrity and the ability to quickly refactor our React components and apps. As it does for Hack, Nuclide supports Flow-specific decorations and editor features in @flow-annotated files.

On the other hand, PlatformIO provides the following key features:

• C/C++ Intelligent Code Completion
• Smart Code Linter for the super-fast coding
• Multi-projects workflow with Multiple Panes.

"Remote development with SSH" is the top reason why over 7 developers like Nuclide, while over 2 developers mention "It is the best" as the leading cause for choosing PlatformIO.

Nuclide and PlatformIO are both open source tools. It seems that Nuclide with 8K GitHub stars and 747 forks on GitHub has more adoption than PlatformIO with 3.18K GitHub stars and 416 GitHub forks.
