I'm looking for an open source headless browser to run on a FreeBSD shared Web server, which can do reasonably accurate rendering of current HTML/CSS/JS.
As I'm not very skillfull with Unix/servers and don't have root access, this should have no dependencies that would not be installed on a typical Apache shared Web hosting server (ruling out Java I believe), and should ideally even be pre-compiled for FreeBSD.
I guess I need a command-line and/or PHP-accessible interface (I'm not too clear on how any of that will work).
From the answers I'm getting this seems to still be an obscure subject. Here's the sort of thing being done with headless browsers:
But rather than turning this question into a general discussion of the subject, can we keep it focused to answers that have specific software recommendations for me -- if any (I suspect what I'm looking for isn't available yet). Thanks
