Honestly, I've not coded in 5+ years ( RoR ) and a project I'm involved with needed a few of days worth of TLC. A combination of Cursor, Warp and OAI Pro has delivered the results with no sweat at all. Upgrade of Ruby 2 to 3.7, a move to jsbundling-rails and cssbundling-rails, upgrade Yarn and an all-new pipeline. It's not trivial stuff for a production app with paying customers.

The obvious crutch of this new AI stack reduced go-live time from 3 weeks to 3 days. Well worth the cost IMHO.

Yeah, I'm skeptical about the price point of that particular product as well.
