Pearler: $9.5 trades. No SWF moat?

https://captainfi.com/pearler-review/

I've just come across this new online broker, called Pearler. $9.5 flat fees, up to $17,500. After this they charge 0.055% of the trade as brokerage.
It seems the main distinguishing factor between Pearler and SelfWealth is the autoinvest and autodeposit feature - pretty much just dollar cost averaging. It also has full sharesight integration, which SelfWealth definitely lacks something of that sort. They have full CHESS as well.
They've also said that all US equities are going to be available in October.

Have you guys heard of them before? I've held SWF since March, and I've always been slightly worried that a duplicate may arrive to take market share.
