Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“End-to-end type safety with Eden treaty is the killer feature. Bun-native performance is excellent.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Bun-first means limited runtime flexibility. If Bun adoption stalls, Elysia is stranded. Hono is safer.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“Type-safe APIs without code generation is the right direction. Elysia's DX hints at what web frameworks should feel like.”
