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.”
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“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.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“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.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
