Arduino IDE vs PlatformIO: What are the differences?
Developers describe Arduino IDE as "A cross-platform application integrated development environment *". It makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. On the other hand, *PlatformIO** is detailed as "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.
Arduino IDE and PlatformIO can be categorized as "Integrated Development Environment" tools.
PlatformIO is an open source tool with 3.29K GitHub stars and 432 GitHub forks. Here's a link to PlatformIO's open source repository on GitHub.
