Reviewer scorecard
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
