Ask HN: What web browser engines are under active development?

There's something called Servo, although from what I understand, it's not going to be presenting any mainstream competition to Chrome any time soon.

Most of the team were laid off [0], Servo was a Mozilla project. They're still reeling, but it looks like Mozilla will be moving their efforts to Firefox proper, rather than integrating the best parts of Servo into Firefox.

lynx is still under active development, so that might count. It uses a fork of libwww as the engine.

Goanna is a fork of Gecko for Pale Moon, but development is slow.

KHTML is basically in maintainence-only, but is WebKit's ancestor.

Ghost Browser

Ghost browser is chromium based. Says it right on their website: https://ghostbrowser.com/
