I'm looking for (free software) alternatives to Parallels Remote Application Server [1][3] or VMware Horizon (formerly called Horizon View) [2]. A software that can be used to access Windows or Linux applications via application virtualization just by using a browser.
I think Citrix Virtual Apps (formerly called Citrix XenApp) can do the same (not 100% sure).
Does a free software solution exist that can do something like this?
