I used and was impressed by Namecheap EasyWP, which seems to be part of what they’ve folded into Spaceship. They really delivered on high performance, serverless, cheap WordPress. Moreover, they proved that Namecheap doing greenfield produces starkly better results than what I’d come to expect from their main website and last-gen hosting.
However, EasyWP also ultimately lost me because they just never implemented DMARC/DKIM/SPF or automatic backups. I’m on board with necessary cuts to legacy and ecosystem compat, but missing these features isn’t that, it’s just an incomplete website – and solving it with plugins and manually synced external services significantly detracts from the value prop. And I’m not seeing either feature explicitly advertised on spaceship.com.
