We want to host our community on companyname.com/community and NOT on subdomain community.companyname.com
Is self-hosting is the only option available? Does Business/Standard plan support subdirectory hosting?
Hi Vivek, welcome to Meta 
On our managed discourse.org hosting, subdirectory support is only available on our enterprise tier of hosting. In general we recommend sticking to a subdomain - it’s faster, lower risk, and easier to maintain.
