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.”
“Real-time UI without writing JavaScript. The BEAM VM handles millions of concurrent connections effortlessly.”
“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.”
“LiveView proves server-rendered real-time UI is viable. For CRUD apps with real-time needs, it eliminates the SPA.”
“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.”
“Server-rendered real-time UI is the sleeper approach. LiveView, HTMX, and similar tools challenge SPA dominance.”
