I can’t vouch for them, but here’s what I managed to dig up on Google:
- Somee – free ASP.NET hosting, 15 MB MSSQL, 5 GB monthly traffic
- ASPSpider – judging by the site.. not very professional?
You are far better off with Azure. All these free hosts are usually very bad. If you don’t have your own credit card, perhaps you could ask a family member or a friend? If they are worried about their card security, it’s far safer to give it to Microsoft than any of those other hosts.
