TL;DR

I pitted three hot AI coding platforms—Blitzy, Devin, and Factory AI—against each other on the exact same real-world AWS Card Demo app, measuring performance with SWE Bench scores, prompt clarity, and how much elbow grease I had to add.

Blitzy impressed with its system-level AI collaboration, Devin leaned on its rigorous SWE Bench pedigree, and Factory AI showed off its Code-Droid engine. By the end, you’ll know which tool churns out the cleanest, most production-ready code and which one still needs a babysitter.
