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.”
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“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.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“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 feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
