- No cron jobs.
- No non-browser client access. Read more.
- File size limited to 10MB at most. Some type of files have their own limits. Read more.
- 1 MySQL account only.
- No remote MySQL access.
- 1 FTP account only.
- No full DNS control as you already figured out. You only get CNAME and SPF records.
- No PHP
mail()access. - No email accounts.
- PHP 8.2 is the only version — there’s no PHP selector.
