A flexible IDE
for the 21st century

Juno will receive no more feature updates. Development focus has shifted to the Julia extension for VSCode.


Juno is a powerful, free environment for the Julia language.

Walks like Python. Runs like C.

Juno builds on Julia’s unique combination of ease-of-use and performance. Beginners and experts can build better software more quickly, and get to a result faster.

Useable real-time feedback.

With a completely live environment, Juno aims to take the frustration and guesswork out of programming and put the fun back in. A hybrid “canvas programming” style combines the exploratory power of a notebook with the productivity of an IDE.

Great for power users, too.

Juno is built on Atom, which means it’s a powerful editor as well as a pretty face. It’s customisable to your heart’s content (though the defaults are pretty good too) and has power features like multiple cursors, fuzzy file finding and Vim keybindings.
