@julian The installation instructions only show SSH-enabled VPS and containers https://docs.gotosocial.org/en/latest/getting_started/installation/metal/

So I don't know how to deploy it to a shared hosting (typically no SSH, FTP, PHP, MySQL/PostgreSQL, and not much else)

About snac, I suppose you mean https://codeberg.org/grunfink/snac2 ? I don't see in the docs any deployment manuals for shared hosting. Everything seems to assume SSH.
