Clients connect to a PGSkiff endpoint over IPv4, and PGSkiff forwards the connection to the database over IPv6. It removes the need to maintain your own proxy or configure a VPN.
One use case is connecting to Supabase when you need access without pooling.
You can try it at https://pgskiff.com.
I’d be interested in feedback on the connection setup and in hearing about environments where this would be useful.
