Reviewer scorecard
“AI-generated full-stack apps running instantly in the browser. The StackBlitz WebContainer foundation makes it actually work.”
“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.”
“Describe an app, see it running immediately. The fastest path from idea to working prototype.”
“bolt.new represents the convergence of AI generation and instant execution. This is how rapid prototyping will work.”
“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.”
“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.”
