"This feels like the biggest improvement in on-platform development since scratch orgs were introduced — really recommend checking out aer if you haven't already. We estimate we spend about 40 hours of development time across the team, every single day, simply waiting for the platform to deploy, compile, and run tests. aer changes that equation entirely."

Jonny PowerCTO at Traction Rec
