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.”
“WebContainers running Node.js in the browser is technical magic. Perfect for bug reproductions, tutorials, and quick experiments.”
“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.”
“The technology is genuinely impressive. Running Node.js in a browser tab without a server is revolutionary.”
“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.”
“Browser-based development will become the default for many workflows. StackBlitz's WebContainers are the enabling technology.”
