You can try nostr:nprofile1qqs2gazhwghppw36yu0muuzqykdrcndzeafml50pnqfcy9xjx5rylsspzdmhxue69uhhwmm59e6hg7r09ehkuef0wvc39h too.

Personally, I use both, they are quite similar, they connect bitcoin buyers and sellers, they encrypt your personal information and don't ask for registration info.

The advantage of robosats is tor by default. With peach you can always use a vpn to mask your real ip.

Oh and robosats use lightning with external wallets and peach is on-chain trades with a non-custodial wallet built-in the app + you can set personal addresses..
