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.”
“Remote caching and affected-only testing save enormous CI time. The project graph visualization is invaluable for large repos.”
“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.”
“If you have a monorepo with more than 5 projects, Nx pays for itself in CI time savings on day one.”
“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.”
“Monorepos are winning. Nx and Turborepo are making them practical at any scale.”
