I'm making a product called Skyportal. It generates a simple portal for your Salesforce data.

During setup you choose tables to connect to the portal, then field options for each table. Fields can be hidden or visible, and read-only or editable.

Your customers can sign in and interact with data (view, edit) that's relevant to them. You can also add permission rules. So if you only want a customer to see products linked to their company, that's all the portal will show them.

Salesforce has their own product 'Salesforce Communities' which is a really flexible platform for creating whole communities. Skyportal is for much simpler portals. We've proudly got less functionality, less configuration and less headaches :-).

Looking forward to your feedback!

Aiming to launch in around 5 weeks - feel free to join the waiting list: http://skyportal.app/
