There are two official editors for Micro:bit; MakeCode and Python. They are browser-based, meaning no software instalation is neccessary and they are also localisable into many languages.


The MakeCode editor can also be used offline if needed.

MakeCode

The MakeCode editor provided by Microsoft makes it easy to program your micro:bit with blocks and JavaScript. It  provides an introduction to structured programming via drag and drop coding blocks that snap together.

Python

Our Python editor provides an introduction to Python programming using the micro:bit. You can add a range of common code snippets to your program and you can also create and use your own Python modules with it. It is based on MicroPython, a slimmed down version of Python designed to run on microcontrollers like the micro:bit

Third Party/Alternative editors

There are a host of editor environments developed by the micro:bit community that also work with micro:bit. They will each contain reference documentation on how to use them.
