TL;DR

Tech with Tim lines up three AI coding buddies—Blitzy, Devin, and Factory AI—and gives each the exact same real-world app challenge to see who writes better code faster and with less hand-holding. He walks us through the initial prompt, compares their SWE Bench scores, and shows how much back-and-forth each tool needs before cranking out working software.

Along the way you’ll spot timestamps for each section (from “Overview” through full demos on Blitzy, Devin, and Factory), plus links to get your hands on the tools, the AWS Card Demo repo, and deep-dive SWE Bench reports. Whether you’re curious which AI assistant reigns supreme or just want to streamline your own dev workflow, this showdown has all the insights.
