I see all these tools are being built on top of Ace but Ace itself doesn't get much love. There are many issues in Ace that needs to be fixed but almost no company is putting resources on it.

Sorry, where does it say it's built on Ace? The copy says Atom is the code editing component.

Atom is built on Ace

I don't think Atom is built on Ace. They had their own system which was powered by React before switching to hand crafted DOM manipulation. Also, Atom's written in Coffeescript and Ace is ordinary JS.

If you look at editor API it's very similar to Ace.


I think they started with Ace but then drifted the code a lot.

What are these issues? I use Ace daily (in Advanced Explorer) and have no issue. It has a syntax checker for JavaScript that is invaluable.
