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 'copy into your codebase' approach is genius. Full ownership, full customization, no version dependency hell.”
“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.”
“Solved the component library problem by not being a library. The most practical approach to UI components.”
“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.”
“Beautiful defaults that look professional immediately. The theming system makes brand customization straightforward.”
