Well suited to tedious, large-scale migrations most developers want automated

Generates real pull requests rather than just suggestions
Founders bring direct engineering-leadership experience, not only an outside automation pitch
White-glove tier removes upgrade work entirely rather than only flagging risk

Cons
No free tier, a real commitment before testing thoroughly
Not built for interactive, moment-to-moment coding assistance
Best value requires having genuinely large-scale, well-defined tasks to automate
No published pricing for either tier, so cost planning needs a sales conversation
Java support remains unavailable as of this listing, limiting reach for JVM-heavy shops
White-glove service pricing likely scales with codebase size and dependency count, an unpredictable cost driver
