There are two IDEs:

    http://www.microchip.com/mplab/mplab-x-ide      (local, not Cloud-based)
    http://www.microchip.com/mplab/mplab-xpress     (Cloud-based)

You also have to install a compiler separately:

        MPLAB XC8 supports all 8-bit PIC MCUs
        MPLAB XC16 supports all 16-bit PIC MCUs and dsPICs      <== mine
        MPLAB XC32/32++ supports all 32-bit PIC MCUs

Hardware supported by MPLAB X:
