I Let 3 AIs Compete to Build the Same App…

I pitted Blitzy, Devin, and Factory AI against each other on a real-world dev task to see which delivers the best code quality, speed, and least manual tweaking. Each platform’s unique approach was stress-tested, and I tracked how much elbow grease I still had to put in as the human programmer.

Along the way, I shared all the links you need—video demos, AWS Card demo repo, and each tool’s SWE Bench report—so you can dive in yourself. Timestamps let you skip to the juicy bits: prompt setup, performance metrics, and side-by-side code walkthroughs. Happy testing!
