Reviewer scorecard
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become essential.”
