Grav is a flat-file PHP CMS: content lives in Markdown and YAML files, and there is no database to provision. It needs PHP with a writable user directory and a cache directory it can write to, so almost any PHP host qualifies, shared hosting included. A provider naming it has written an installer or a guide; the rest can run it without saying so.
3 providers document support for Grav, listed alphabetically. Mostly platform as a service, shared hosting and serverless, of 4 categories in all. 88 records do not record this field, and cannot appear here either way.
