I Let 3 AIs Compete to Build the Same App…

Tim puts Blitzy, Devin and Factory AI head-to-head on a real-world coding challenge—same prompt, same task—to see which platform writes the best code with the least hand-holding. He walks through each tool’s setup, prompt engineering tricks and SWE Bench performance, then ranks them on quality, speed and how much elbow grease you still need as the dev.

Along the way he drops timestamps for the demo, shares deep dives on each AI’s technical report, and even plugs his DevLaunch mentorship for anyone who wants hands-on coaching beyond these flashy demos. It’s a fun, no-fluff teardown of what the hottest AI coding assistants can really do.
