Reviewer scorecard
“At $500/mo it needs to replace at least 10 hours of developer time per month. In my testing, I spent more time reviewing and fixing its output than I saved. Not there yet.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“The marketing writes checks the product can't cash. 'Autonomous software engineer' implies reliability that doesn't exist. It's a talented intern that needs constant supervision.”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“Devin is early but directionally correct. The autonomous agent approach will win eventually. Cognition has the best shot at getting there first. Invest in the future, not the present.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
