Listing which of these browsers are actually headless would be a great addition!

Basically, some of these browsers (nightmare comes to mind) use electron as their runtime, and electron requires a working X11 install!

Personally, I think if a browser requires X to be installed, it's not really headless, but in any event, this is a critical distinction for many use cases (I do a bit of browser automation, entirely in environments that don't have any X install whatsoever).

If a "headless" browser requires X and xvfb, at that point you might as well just run full chromium or firefox with webdriver or similar.

It'd be nice to disambiguate between "headless", as in "doesn't open a visible window" and actually headless, as in has no requirement for a framebuffer or X11/etc...

Also nightmare here is listed as a lib for controlling PhantomJS, it used to be, but this is now incorrect and as you said it also now requires X11 due to using electron.

We have close to a hundred projects listed here, so this could take a while. PRs are welcome and encouraged :)

I wasn't sure what the goal of this list was, so I didn't want to start creating pull requests without actually talking to someone first.

This list is meant to be a list of all headless browsers in existence, and we'd rather include projects than not, even if part of the criteria for "headless" is not met. But we're happy to classify these projects as such :)

Ok. My concern was mostly releated to how "headless" is defined (mostly who's opinion it's based on), and the project scope.

If I can get some time, I'll PR some stuff.

[dhamaniasad]

We can define headless as whether or not the project has X related dependencies. I'll get started on going through projects and adding the distinction to the list. PRs are welcome and appreciated! :)

Browsers are now categorized by driver type.
