How can I install Google Chrome on OpenBSD?
Chrome has been in OpenBSD's ports tree since at least OpenBSD 4.8.
$ sudo pkg_add chromium
Should do the trick, assuming your PKG_PATH environment variable is properly set.
For more information on ports/packages, see here: OpenBSD Packages and Ports System
I am just revising the answer for OpenBSD 6.3 which uses 'doas' instead of 'sudo':
- modify doas.conf
permit nopass as root
- Execute the pkg_add for to install chromium
doas pkg_add -v chromium
