Integrating the IDE directly into VS code. Support a lot of Hardware Platforms and Software frameworks. Built-in debugging tools and performance analyzers. Really good community support.

The best thing for me is that it is Open source. I also like its cross-platform IDE and Unified Debugger; it is very light & has helpful features like "smart code completion."

Firstly the domain this platform is in isn't much crowded, and that's why finding something that has the most things you need has always been a struggle. But PlatformIO has provided such an amazing experience to everyone who uses it that there's no need to check out other solutions. In my opinion, the best features of the platform are - - Remote Development: This is, I think industry-first feature that lets you code/work on your project. Even though you aren't connected from your system they provides you a virtual machine with great computing power where you can do pretty much everything. - Great UI: PlatformIO has a great Developer friendly UI so that one won't face any UI/UX issue. - Predefined debugging configs - Here comes the thoughtfulness of the platform obviously you can debug in this, but along with that the platform has provided pre declared configurations for debugging which really helps a lot. - The unit testing feature is also works like a breeze
